Answer:
It is an equation where the reactants are equal to the products
Step-by-step explanation:
A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side.
For example:
A+B=AB
on the left side (reactants) you see 1 A and 1B. on the right side, you see 1A and 1B. It is balanced if atoms on left are equal with atoms on the right.
