The correct statement about the balanced equations for nuclear and chemical changes is:
A chemical equation is balanced according to the mass number of each element before and after the change. On the other hand, a nuclear equation is balanced according to the total mass before and after the change.
To balance a chemical equation, you need to ensure that the number of atoms of each element is the same on both sides of the equation. This is done by adjusting the coefficients in front of the molecules or compounds. The mass number, which is the sum of the protons and neutrons, does not change during a chemical reaction, so it remains constant on both sides of the equation.
On the other hand, nuclear equations involve changes in the nucleus of an atom, such as radioactive decay or nuclear reactions. These equations are balanced by considering the total mass before and after the change. The mass number can change due to the release of particles or absorption of particles during a nuclear reaction.
In summary, chemical equations are balanced based on the mass number of each element, while nuclear equations are balanced based on the total mass before and after the change.
