Question

Question 5 of 10Reactions need to be balanced. Why is that?A. Reactions should be balanced because of the conservation ofenergyB. Reactions should be balanced because atoms are not lost orgained in a chemical reaction.C. Reactions should be balanced because the volume of reactantsmust equal the volume of products,D. Reactions should be balanced because the reactants must be theexact same as the products.

Answer 1

Atoms are not lost or gained in a chemical reaction.

Explanations:

Equations are known to be balanced if the total number of moles of elements at the reactant is equal to that of the product.

This is important since matter cannot be created or destroyed in a chemical reaction according to the law of conservation of matter. Therefore we can conclude that reactions should be balanced because atoms are not lost or gained in a chemical reaction.
