Balancing Reactions

We learned how to balance chemical reaction equation. For this to happen, the chemical must follow the Law of Conservation of Mass, which says you can't make something out of nothing, and vice versa. To do this, you must make it so that each side of the equation has the same number of each chemical, as shown below:

To see it done, just go to THIS video.

It is a relatively simple idea, but can be hard, and is needed for the entire area of Chemical Reactions.
