Which statement about the balanced equations for nuclear and chemical changes is correct? (1 point) Both are balanced according
to the total mass before and after the change. A chemical equation is balanced according to mass number. A nuclear equation is balanced according to the total mass before and after the change. Both are balanced according to the mass number of each element before and after the change. A nuclear equation is balanced according to mass number. A chemical equation is balanced according to the total mass before and after the change.
Both nuclear and chemical equations are balanced according to the total mass before and after the change.
In every equation or reaction, the total mass of the reactants must be equal to the total mass of the products. In other words, all reactions - be they chemical or nuclear - must obey the law of conservation of mass.
The law of conservation of mass states that mass can neither be created nor destroyed, but can be converted from one form to another during a reaction.
Thus, in order to balance reactions involving chemical or nuclear reactants, the total mass before the reaction must be equal to the total mass after the reaction.
