Question

Which statement about the balanced equations for nuclear and chemical changes is correct? (1 point)
o A chemical equation is balanced according to mass number. A nuclear equation is balanced according to the total mass before and after the change.
o Both are balanced according to the total mass before and after the change.
o Both are balanced according to the mass number of each element before and after the change.
o Both are balanced according to the mass number of each element before and after the change.

o A nuclear equation is balanced according to mass number. A chemical equation is balanced according to the total mass before and after the change.

Answer 1

The true statement about the balanced equations for nuclear and chemical changes is; both are balanced according to the total mass before and after the change.

A basic law in science is called the law of conservation of mass. Its general statement is that mass can neither be created nor destroyed.

Both in chemical and nuclear changes, mass is involved and in both cases, the law of conservation of mass strictly applies.

This means that for both chemical and nuclear changes; total mass before reaction must be equal to total mass after reaction.

Hence, both reactions are balanced according to the total mass before and after the change.
