This video is based on a chemistry experiment. This video is going to explain to us how to use gravimetric analysis in order to analyze sulfuric acid. This experiment should not be done for those who do not have a fundamental knowledge of chemical compounds, reactions and chemical safety. He explains first what he is about to do before he does it. Sulfuric acid is acidic and can be toxic if ingested or in contact with the eyes. Take extreme care with this experiment.

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...

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...
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...

You can figure this out b doing a basic equation for all of the chemicals. Fill this in with the correct information, then the answer will be done. Make sure you understand ...
In this video, we learn how to balance chemical equations with ease. First, you will need to take down the equation and find out how it is formed and how much each of the chemicals are in it. Draw a diagram if you need to so you have a visual key. If you figure out how many of each of the chemicals are in the equation, then you will know how to balance it out. You will make sure that both the right and left have the same number of chemicals and mass. Balance this out by adding in more chemica...
In this video, we learn how to balance chemical equations using a simple method. Start out by writing your two chemicals next to each other. After this, you will need to write out how much of each atom each of the chemicals has. Now you will have a better idea of how you need to balance out each of the different equations. Make a chart of all the elements that are involved, then you can solve it. Use simple addition to add together the atoms of each and then write out the correct answer in th...
In this video we learn how to balance chemical equations the fun way. First, remember that matter cannot be created or destroyed. Take two different types of chemicals and put them on opposite sides of the equation. If you have more mass on one side than the other, these will not balance out. Once you have equal amounts of mass on both of the sides, you will be able to balance the chemical equation. Remember this rule whenever you are balancing out chemical equations. Use visual markers to he...
