What Does Mixture Mean in Chemistry?

What Does Mixture Mean in Chemistry?What does mixture mean in chemistry? It is the blending of two chemicals that are chemically different. The mixing process is quite simple if you follow these simple steps. The next thing you need to know is the use of a reductant when mixing up the ingredients, and this process must be done carefully.You have to choose a chemical that is safe for your students to use, and you want to choose one that they would have no reaction to when using it. Mixing of two chemicals is a very common task in chemistry. Mixing up the chemical can be in the form of mixing up dry and wet chemicals. A dry chemical is something that is not too wet, and a wet chemical is something that is too dry.Once you have chosen the dry chemical to use for mixing up, you will need to mix up the wet chemical. This can be done in several ways. You can use your hands to mix the dry chemical, or you can use a machine that will do the mixing for you. The machine that you choose to use for mixing the dry and wet chemicals will depend on the amount of time that you have in which to complete the chemical mixture. You can choose the machine that is easy to use, and you will not have any problems with how you mix the chemical mixture up.You will also need to know what quantity of dry chemicals you need to have to complete the chemical mixture. Generally, the more chemicals that you have, the more money you will need to spend. One way that you can save money by choosing this method is that you can make the chemical mixture yourself at home. Make sure that you know the proper methods and procedures to use when doing this.Make sure that you have all the equipment that you will need to complete the chemical mixture. You will need to have a stirring stick, and you will need to have the correct amount of redox electrodes for the chemical. You will also need a separate mixing container, so that you can mix up the wet chemical and the dry chemical. Make sure that you have all the chemicals ready before you begin the chemical mixture. Make sure that the right amounts of all the ingredients are available, and that the preparation is correct.Now that you have prepared the chemical mixture, all that is left is to add the wet and dry chemicals to each other. You will need to stir the mixture well before the chemical combination will be complete. When all the chemicals are mixed together, you will want to do a final stirring to ensure that all the chemicals are mixed up. Once you have done all of this, you will want to try the mixture out. If you find that there are some problems, you may need to add a bit more acid to the chemical mixture, or you may need to change the proportions of the chemicals to suit your needs. Be sure to let the mixture cool before continuing with the procedure.Make sure that you understand what happens when you perform the chemical mixture, and how it works. When you understand how the chemical mixture works, you will find that it is much easier to make the mixture up and mix up the chemicals at home. You will find that it will be easier to do the chemical mixture at home, and you will learn to do this job much more easily.

Can I get a teaching degree online

Can I get a teaching degree online Are you considering enrolling in an online teaching program instead of a classroom-based one? Well then, you’re in luck! As distance learning becomes more and more mainstream, the majority of public and private four-year institutions in the US now offer a wide variety of highly reputable, accredited online teaching degree programs, spanning the bachelor, master and doctoral levels. There are a ton of options out there that are well worth exploring and that offer the same rigorous training and virtually the same job prospects as regular classroom-based teacher training programs in your state. As long as you go opt for an accredited program, your degree will be just as valid as a degree earned through an on-camps teacher education program. 1. Getting your bachelor’s degree in education online. Most online bachelor’s degree programs in education allow participants to specialize, either on a specific grade/age level or subject/content area. These programs will usually help you work towards obtaining a teaching license in the state you want to teach in. However, online bachelor’s degrees in education leading to teacher certification are less common than online graduate degree programs designed for current teachers. If you do find a suitable online teaching degree program offered at the undergraduate level, be warned that while most of the coursework can completed online, you will still need to complete a semester of student teaching in person before you can qualify for your teaching license. It may, however, be possible to complete your student teaching in your local area. So overall, while online bachelor’s degree in education programs are not technically 100% online, these do offer much more flexibility than a traditional, in-person teacher preparation program. Not having to go to class at a set time each week is ideal for anyone already juggling work and family commitments or who lives some distance away from a school of education. If you prefer to learn at your own pace, on your own time, getting a teaching degree online might be just the thing for you! Admission requirements for online bachelor’s degree programs are similar to their on-campus counterparts (usually a high school diploma and admissions test) and take around four years to complete.

They typically take two years to complete and popular options include: MA in teaching MS in education There are a select few online master's programs that are designed to give a pathway to teacher certification for people who have an undergraduate degree in an unrelated field or working professionals looking to transition into teaching. There are also online doctoral degrees in education primarily geared towards working educators who are looking to: Move into research or education policy Teach at the college/university level Pursue an administrative or leadership role 11 accredited online teacher certification programs Regardless of whether a program is delivered online or on campus, a traditional teacher preparation program or an alternative certification program, it’s critical to confirm it: Holds regional accreditation Is state approved The most well known accrediting body for teacher training programs in the US is the Council for the Accreditation of Educator Preparation(CAEP). Note:Most of the following state-recognized online teaching degree programs qualify graduates to apply for licensure in the state where the school is located. However, some of these may also be eligible for teaching licensereciprocityin your home state. Be sure to check with your department of education regarding licensure requirements and whether any of these meet their criteria.

While an alternative teacher certification program will get you into the classroom as a working educator faster (in under a year in some cases), online options are less common, with a few notable exceptions includingiTeach,Teachers of Tomorrow,TeacherReadyandTeach-Now. Why’s that? Well, online alternative teaching certification also typically require you to undergo a teaching practicum at a local school in the state you want to teach in, which you may need to arrange on your own. Before you commit to an online alternative certification program, you’ll need to be sure that you can arrange your student teaching to take place close by - or be in a position to relocate temporarily over the course of the student teaching component of your course. Graduates who desire to teach in public schools in any state must be licensed. Specific requirements vary based on location, but generally, individuals must have a bachelor's degree in addition to completing an accredited teacher education program with student teaching. They must pass a teacher certification exam and, in some cases, additional assessments focused on particular content areas, according to the U.S. Bureau of Labor Statistics. Final word of advice:If you’re looking to teach in a public school in any state, you must be licensed. Requirements for licensure do vary state by state, but at minimum, will usually include a bachelor’s degree and completion of an accredited teacher education program with a teaching practicum. For more details on earning your teaching license after completing your teaching degree online, check with your state’s department of education. Good luck!

Thank You, Emma Watson, For Showing Us What Feminism Looks Like

Thank You, Emma Watson, For Showing Us What Feminism Looks Like http://www.socialtalent.co Why is feminism a word with such negative connotations? As an adolescent, I realized how much of my beliefs rooted in feminist ideals. I watched as girls around me dropped out of their sports and leadership roles to become more girly, to not seem too aggressive, and to ultimately lose their confidence in themselves. I was forced to suppress my feminist views when I was in high school, because even my girl friends disagreed with me, saying if I was going to be a feminist I shouldnt expect guys to be chivalrous, pay for dates or assume the usual male roles in a relationship. But I was in high school, so my adolescent brain told me if I wanted a date to prom, I probably should keep these opinions to myself. Luckily, as I became a college student, I realized how I am not alone at all in my stance on feminism. I came to realize that not only am I not alone, but this problem is bigger than I even imagined. The fight to gain gender equality is that the word feminism has become synonymous with “man-hating, armpit hair-growing, liberal lunatic.” When I tell the guys in my life that I am a feminist, I’m lucky if all I get in response is an eye roll. This shouldnt be a word that is so tabooby definition it is the belief that women and men should have equal social, political and economic rights. Men and women both need to realize this; feminists are not fighting to gain an anti-male following, but to abolish the horrible stereotypes that women so often receive. For me, the hardest part of this struggle to gain social equality is watching my girl friends use derogatory words about other women. “She’s a total slut,” or “Don’t wear that, you’ll look like a whore,” are phrases thrown around so often that they have become a societal norm. Why do we, women who are struggling to become successful people, use these words (which were created by men to show ownership over other women) when referring to other women? We are only putting ourselves down when we “slut shame,” making it seem as though we are okay with being called “sluts” to the point that we will use it ourselves. There is no term to refer to male promiscuity, yet there are dozens of derogatory words to speak about sexually promiscuous women. Society views a sexually active guy as a real macho man, but a sexually active woman as a slut. Feminism isnt about burning bras and refusing to shave your leg hair. Its about giving yourself or the women you care about the chance to be all that you/they can be without discrimination. Although we live in one of the best time periods in history for women to coexist with men, there is still so much separation between genders. Thank you, Emma Watson, for bringing this issue to international attention, because these acts of feminism-hating, inequality and slut-shaming need to come to an end.

The ultimate guide to landing an English teaching job in France ?

The ultimate guide to landing an English teaching job in France ? Teaching English in France is a bit of a dream, right? Whether you’re curious about finding a rural school nestled in the Pyrenees or an International School in one of the cities like Lyon or Paris, the bread alone will be incentive enough to pack your bags and book a flight ??. France has a whole new world to offer international ESL teachers and bread really isn’t the main attraction. They have pastries too . Jokes aside, France is one of the nicest countries to spend a stint of time: mountains, quaint villages, bustling cities, vineyards, wine tastings, and a countrywide appreciation for the endless potential of butter. And when you’re done with oohing and ahhing over all that, this is the country where even their cliches are philosophical: c’est la vie, joie de vivre and je ne c'est quoi. Let’s face it, pretty much everything sounds better in French. It’s no wonder it’s one of the most romanticized countries in the world and a place where many English teachers dream of landing a teaching abroad job. Alright, spill! What’s the magic “teach-in-France” formula? If you’re looking to land an English teaching job in France there are a few ways to go about it and it’s largely going to depend on where you’re from. Oh and also, that you have the golden ticket (aka a TEFL certification). If you’re an English speaker from a European country, you can pretty much book a flight/train/boat, land on French shores and mosey around with a resume. But candidates coming from further afield are going to have to look into visas and teach abroad programs. We’ve got all the information you need on both below and links to useful resources and programs that will make relocating to France that much easier! OKAY but I’m not European, how do I get a job teaching English in France? Calling all Americans, Canadians, South Africans, Jamaicans, Australians…you get the idea! There are a lot of non-European native English speakers that probably want to teach English in France and for this group of people, we would steer clear of just rocking up and expecting to find a job. France is not big on hiring English teachers under the table like other countries and you might end up on a return flight before you’ve even said Bonjour! C'est évident, je suis ici pour enseigner! Aside from Europeans, Canadians have perhaps the clearest route to teaching abroad in France as they’re eligible to apply for a working holiday visa. The visas are generally a year long and if teachers want to renew them and stay in France (and who wouldn’t want to stay in France?), they should do so two months before they expire. The only stipulations are that applicants are between 18 and 35 years old, have a Canadian passport and have sufficient financial resources to cover their set-up costs. Australians and New Zealanders should also be able to apply for a working holiday visa. Non-EU citizens (including Canadians) can also teach English on a student visa or applying for the TAPIF program. NOTE: If you’re an American teacher, then TAPIF is most likely your best bet! Recommended reading: My experience teaching English in France What are the requirements to teach in France? ? Teaching English in France has a number of requirements. Although there are as many exceptions as there are rules. It’s generally a good idea to have a TEFL certificate and a BA degree. Some teaching experience won’t go amiss either. That being said there are plenty of voluntary positions, summer camps and even online teaching opportunities which may be slightly more lenient when it comes to your qualifications. To sum it up: If you want to make sure you land a job teaching in France make sure you have a TEFL certificate and a degree! Otherwise, you may not get an opportunity to pack your bags and binge on baguettes. Side note: Who said you have to teach French students while living in France, with the lowish cost of living, you could always live in France and teach online. Or use teaching online to supplement your income. All the more money for wine we say! Just a thought! So, when is the typical hiring season for English teachers in France? If you’re planning to teach part-time, do freelance private sessions, teach online or just volunteer to teach English in France - the chances are you can easily get hired at just about any time of the year. A lot of local language schools and international schools prefer to hire in person around the end of the summer when school starts back (so from August to October) with a second hiring season in January. Summer camps tend to hire from January onwards to fill their summer slots. It completely depends on the type of school you want to teach at and it’s worth doing some research around the kind of school you want to teach at and when they generally hire. Read this: Typical hiring seasons for English teachers globally. Save before you go - you’ll need start-up dollars Particularly if your game plan is to land in France and see how it goes, you are going to need to have some savings. You probably won’t use them all, but setting yourself up in a new country is rarely cheap. From bedspreads to dishes, getting an apartment to a remotely livable standard isn’t cheap. You’ll need to cover flights, deposits and well… that slightly important substance called food. If you’re wondering how much money you need to bring, we’d say that about $3,000-$4,000 should cover everything comfortably for the first couple of months. But you could definitely survive on a lot less. Most of the money will go toward finding a place to rest your head at night and getting yourself set up in the country. If you live in Europe already, then long-haul flights won’t be a worry, but Canadian applicants are going to want to have enough money to get themselves to France. I can’t afford Paris, what else is out there? Plenty! Nothing brings greater joy than googling places to teach in France. The demand is such that you’re likely to have your pick of the cities. Some of the best cities to teach English in France are Toulouse, Lyon, Bordeaux, Nice, Marseille, Nantes, Montpellier and Strasbourg. But that list is by no means exhaustive! How will I find a place to live? One of the big tips for finding housing is to apply for CAF. This is a grant for people with low incomes or students, that could be helpful. It could be a bit of a pain and long-winded, so if you want the financial assistance be sure to apply for this as soon as you arrive. Some programs, like babylangues are happy to help their teachers with this sort of thing. Seeking accommodation is one of the most daunting parts of landing in a new country or well, you know, continent! The best thing to do is get a cheap hostel or airbnb while you get your bearings. Often schools will help you negotiate a better deal. It’s also wise to stay somewhere temporary until you know where you’ll be working. If you end up with two jobs at different ends of a city, plonking yourself in the middle might be the best solution.. A lot of teachers tend to get private hours in multiple schools and making sure you live somewhere that is convenient to all, is a major consideration. Public transport can be a lovely way to spend time seeing the city and listening to podcasts… but it can soon lose it’s gloss if you’re spending a disproportionate amount of time slouched on a bus/train. Where do I research schools? This one is easy, there are tons of jobs boards out there. Here are just a few places where you’ll be able to find jobs with French schools that might help you out! The TAPIF program website Pages Jaunes (or the yellow pages!) Teach Away Dave’s ESL Café ESLBase Babylangues Failing these, there is no harm in having a Google or Reddit perusal. Just because a job isn’t posted on a jobs board, it doesn’t mean nobody is hiring! Sign up to Teach Away today for access to the latest teaching jobs around the world. How much can I save teaching English in France This is going to be different for everyone. The typical private tutoring session will pay between $17-$22. How much you make and save will vary from teacher to teacher, and depend on how many hours you work, if you’re willing to work at multiple schools and if you do a bit of online teaching to supplement your income. That being said, if you’re really just there to see Europe, you can easily work lightish hours to cover the bills and spend your weekends railing around Europe. Train tickets in Europe aren’t that expensive and with a magical interrail pass - you could see a lot of the continent for a minimal expense. Some little tips to make that teaching resume sparkle ? The likelihood is that you’re going to need to send your CV/resume around to schools. Why not get it translated into French? And how about that cover letter too? It will make your application look like you are invested in getting a teaching job and respectful of the language and culture. On a similar note - schools are often looking for someone already in the area. So as soon as you land, look into getting a local number. Even if it’s just a case of unlocking your phone and getting a cheap SIM card with a French number. That way employers will not have to think twice about calling your number.

We can learn about the difference between solvents and gasses, the interrelationships between them, and even how different reactions relate to one another by reading about the concept of chemistry.In today's world, we are inundated with plenty of things that have chemicals in them. Even the things that are made of plastic have to be coated with some sort of chemical. Learning chemistry will help us recognize the role that chemicals play in our everyday lives.If you have a chemical engineering degree, you may want to look into working as a chemical engineering consultant. You'll need to know the science behind the construction of a structure, such as buildings and pipelines. You can help these companies improve their designs by explaining to them how elements in materi als react and why.Chemical engineering isn't just useful in structures. It also helps engineers to keep track of different compounds that are used in many kinds of industries. It is vital to the industrial process because it determines how a compound interacts with other compounds and with matter at its surface.For example, how do you compare pesticides and herbicides? A chemistry degree is necessary to answer this question. A degree is needed to determine the chemical properties of each compound, such as how long it takes for a compound to break down, how damaging it is to plants, and how long it takes for something to damage its surroundings.If you have a college degree in chemistry, you can consider working as a chemical engineer for a common industry, like a pharmaceutical company. Chemical engineers are responsible for designing products that have been developed in collaboration with researchers. They are concerned with the ability of a product to interact with a variety of dif ferent substances. As an example, a pharmaceutical company might use a chemical that has been tested to help people with allergies to citrus fruits.The reason that a chemistry degree is a common thing is because it teaches the process of chemistry. Although your career may involve it, you can actually do a job of using it, too. This is how to use a chemistry degree to make a living!

Why is My Guitar Feeding Back A Guitar Feedback Guide

Why is My Guitar Feeding Back A Guitar Feedback Guide Megan L. Does your guitar make a shrieking noise when you sing and play? Do you want to harness its power for good? Here, guitar instructor Zachary A. explains the phenomena of guitar feedback and how it can be manipulated to enhance your music An Example of Feedback The first thing that comes to mind when I think of guitar feedback is Jerry Garcia, the guitarist for the Grateful Dead. Creating a paralyzing shriek, he manipulates guitar feedback  in a wizardly fashion, pushing the boundaries of the electric guitar and his amps. Below is an example of Garcia  playing around with feedback. When you  think of feedback, youll likely remember  sitting in a class assembly as the person at the podium conducts their  speech, a loud shriek comes over the auditorium. This screech, which is referred to as feedback, happens mainly due to a sound loop that occurs between an audio input device (a guitar or microphone, for example) and an audio output device (an amp or speaker). What Causes Feedback? All thats needed for feedback to occur is the components of a basic public address system; a public address system consists of a microphone, amp, and speaker. Feedback happens when sound is amplified out of the speakers, then travels back through the microphone, and is amplified again, and then sent back through the speakers for a second time. This loop happens so fast that it creates its own frequency, which results in the infamous shrieking noise. Its one of the many guitar tones that you can produce. When musicians talk on the subject of feedback, the comments are mostly negative due to this howling sound thats produced in the middle of the song theyre trying to play. In addition to the dreaded sound loop, feedback occurs when the gain is too high in the output of an amplified instrument. As well as ways to minimize and control feedback, there are many ways to increase the chances that feedback occurs. One main point that needs to be reiterated is that feedback occurs in a system thats at a point of high gain and resonance. This can make it particularly challenging to control, but it can be accomplished. How to Prevent Guitar Feedback First, well discuss ways that you can reduce the chances of feedback happening. Then, well dive deeper into the ways of working magic with feedback. One major change you can make  to keep feedback down is by monitoring the amplified volume of your instrument in relation to the space that youre playing in. Another quick and painless way to reduce feedback is to change the position of your microphone and or speaker so that the speaker output isnt feeding directly into the microphone. Keep the speakers further forward, closer to the audience, then the microphones further back. Other ways to avoid the dreadful shriek are to use a directional microphone. Also, speak or sing close to the microphone; practically kissing the microphone. Also, turn off the microphone when its not in use, thus equalizing the signal and lowering the frequency. Another way is to lower the speaker output. There are devices you can purchase that can be connected in between the monitor and the amp in order to reduce the amount of audio frequency that occurs. How to Manipulate Guitar Feedback Feedback can be used as a very interesting tool for a musician, as we heard in the Jerry Garcia video. There are a few ways to increase your chances of feedback happening  so that you may utilize this technique. For example, use a higher gauge string they vibrate for a longer period of time  and require less feedback from the output to hold a note. Its just another way to transform your guitar sound. Another simple cosmetic change you can make to increase the amount of sustain and feedback your instrument produces is by making the guitar as rigid as possible. If you have a bolt-on neck, make sure the screws are tight or this will reduce the sustain of the strings. The old method to increase feedback was to connect a treble boost before the amplifier to overdrive it. Another cosmetic feedback enhancer that can be done is lowering the pickups to increase the distance between the pole pieces in the pickups and the strings. Although some people choose to raise the pickups to produce maximum drive to the amplifier, this will decrease the amount of feedback that may occur. Unfortunately, pole pieces are magnetic and close proximity to strings will dampen the vibrations. Now go out and create some scary horror movie sounds using feedback and get creative with it. You can use feedback to convey a vast range of sounds and emotions! Happy playing! Post Author:  Zachary A.

Solve the following System of Equations - Online Tutoring

Solve the following System of Equations - Online Tutoring System of equations are more than one equations which contain the same solution. To solve a system of equations we require the same number of equations as the number of unknown variables. An equations can consist of one or more than one unknown variables with different coefficient numbers and constant numbers. Example 1: Solve the system of equations x - y = 10 and x + y = 6? Solution: The given equations are x - y = 10 and x + y = 6. Here x, y are the unknown variables. Substitute the variable x. From one equation x = 10 + y, substituting in the other equation. This gives 10 + y + y = 6; 10 + 2y = 6; 2y = -4; y = -2 Now substitute y = -2 in x + y = 6; x = 8. Hence the solution is x = 8 and y = -2. Example 2: Solve the system of equations x - y = -3 and x + y = 1? Solution: The given equations are x - y = -3 and x + y = 1. Here x, y are the unknown variables. Substitute the variable x. From one equation x = -3 + y, substituting in the other equation. This gives -3 + y + y = 1; 2y - 3 = 1; 2y = 4; y = 2. Now substitute y = 2 in x + y = 1; x = -1. Hence the solution is x = -1 and y = 2.
