Answer:
C. Balancing a chemical equation simply means ensuring that the same numbers of atoms of the elements which are involved in the reaction (reactants) are represented in the result of the reaction (products). This demonstrates that matter is not created nor destroyed in a chemical reaction.
Explanation:
The products of a reaction contains a certain number of each atom constituting each product;
Matter cannot be created or destroyed so the reactants must contain the same number of each atom;
Balancing the equations means this will be the case and hence, this will demonstrate the number of each reactant atom/molecule necessary for the reaction to proceed
