Question

what is the balanced chemical equation

Answer 1

the reactant and product. must be balanced equally.
total mass of element present in the products of chemical reaction has to be equal to the total mass of elements present in the reactant this is known balanced chemical equation

Answer 2

I.e.
reactants=products
