In this video, we learn how to properly balance chemical equations. You will see what substances are in each side of the equation. You will then need to count the atoms that are on each side of the chemical equation. Once you write down the number of atoms on each side, you will need to even them out. To do this, you need to change the coefficients within the equation. These change the total number of atoms inside of a chemical. Once you do this, you will add more to each atom present and the...

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.

Once you have these balanced out so they are the same then you will have it complete...
