Answer:
a)<em> Balanced equation:</em>
An equation is called balanced if there are same number and same type of atom on both sides of the equation.
b)<em>Reason:</em>
2KClO3--------2KCl + 3O2
Consider this equation in the reactants there are 2KClO3 and in the product there are 2KCl+3O2 . So reactants =products which is a case of balanced chemical equation .
