Which property is conserved in both nuclear reactions and chemical reactions?
A. Total number of protons and neutrons
O B. Number of atoms
C. Total mass of atoms
O D. Type of atoms

A. Total number of protons and neutrons

Explanation:

In both nuclear reactions and chemical reactions, the total number of protons and neutrons are conserved.

It implies that the starting number of protons and neutrons in both reactions must be the same.

Chemical reactions involves, loss, gain or sharing electrons between two atoms.

Nuclear reactions deals with the nucleus of an atom.

It must be ensured that the mass and atomic number in nuclear reactions is conserved.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.
