Question

In a nuclear fusion reaction, the mass of the products is(1) less than the mass of the reactants because some
of the mass has been converted to energy
(2) less than the mass of the reactants because some
of the energy has been converted to mass
(3) more than the mass of the reactants because some
of the mass has been converted to energy
(4) more than the mass of the reactants because some of the energy has been converted to mass

Answer 1

The correct answer is option 1. The mass of the products is less than the mass of the reactants because some of the mass has been converted to energy. Fusion reaction happens when two or more nuclei combine or collide to form an element with a higher atomic number. In this process, some of the matter of the fusing nuclei is converted to energy.
