in a chemical reaction. Therefore, the same charge must be present on both sides of the unbalanced equation. One balances a chemical equation by changing the scalar number for each molecular formula. Simple chemical equations can be balanced by inspection, that is, by trial and error.

In other words, we seem to have lost one O atom along the way! To write a chemical equation correctly, the number of atoms on the left side of a chemical equation has to be precisely balanced with the atoms on the right side of the equation. ... This implies that mass is also conserved during a chemical reaction.
