While at work, you notice your gloves changing color, and you know immediately that you've come in contact with dangerous chemicals. Bandages on a patient signal the presence of unseen, drug-resistant microbes. These are ideas that might have once seemed futuristic but are becoming a reality as researchers move forward with technology to use living bacteria in cloth to detect pathogens, pollutants, and particulates that endanger our lives.
In this video we learn how to balance chemical equations using a teacher's guide. A chemical equation is a brief way of summarizing what happens inside of a chemical reaction. When you mix up two different chemicals, they will create new types of chemicals in the equation. You have to take these new chemicals into equation when you are trying to balance it out. The mass on both sides must be the same as well as the number of different chemicals on each side of the equation. Try out practice e...

n this tutorial, we learn how to balance chemical equations. This is a straight-forward concept to balance out both sides of the equation of chemicals. To start, you will need to analyze how many atoms in each chemical you have on each side. Once you do this, you will need to find what you can multiply by on each side to make them equal to the other side. Once you do this and have equal atoms on each side, then the equation will be equal. Remember that you cant have a half of an atom, so that...

It's a shame that one of the world's tastiest foods can be such a pain to prep. Most cooks are familiar with this conundrum: chopping or crushing garlic releases a pungent liquid that causes bits of garlic to stick your knife and hands, creating a messy affair. So what is going on here? The common assumption is that the garlic is releasing some kind of oil, but the truth is that this liquid rinses away easily in water. Yet one of the basic precepts of chemistry is that oil and water don't mix.
In this video we learn how to balance chemical equations properly. What is a chemical equation? It's a statement that uses a chemical formula to show identities and relative amounts of the substances involved in a chemical reaction. To balance an equation out you must have the same number of atoms on both sides of the chemical equation. Or, you must have the same amount of mass or matter on both of the sides. Once you have these balanced out so they are the same then you will have it complete...
Olivia and Andrea created a song to the tune of "I'll stand by you" by the Pretenders to teach you how to balance chemical equations. A chemical equation requires coefficients in order to be balanced. You can balance a chemical equation by making use of the Periodic table. The example reaction in the song is that of aluminum and oxygen to produce aluminum oxide (Al + 02 -> Al203). You can systematically add coefficients to the reactants and products to balance the equation. A chemical equatio...
