Question

which change will always take place in nuclear fusion? (1 point) the total charge will be less than before the fusion took place. the total charge will be greater than before the fusion took place. a nucleus with a greater mass than any of the reactants will be produced. a nucleus with a smaller mass than any of the reactants will be produced.

Explanation:

In nuclear fusion, mass - energy is conserved. Some mass is converted into energy according to $E = mc^{2}$. The total mass of the products is less than the total mass of the reactants because of the mass - energy conversion. Charge is conserved in nuclear reactions. So, the total charge before and after fusion is the same.

Answer:

A nucleus with a smaller mass than any of the reactants will be produced.
