During chemical changes matter cannot be created or destroyed. It is merely rearranged. Example

Balancing Equations. O atom. H atom. During chemical changes matter cannot be created or destroyed. It is merely rearranged. Example hydrogen + oxygen =====> water 2 H 2 + O 2 ====> 2 H 2 O. Notice there are the same number and kinds of atoms on both sides of the equation.
