Proton and neutron because e does not matter much
and the mass of atom as you already know is consist of p and n
First consider and take note of the following:
1. When 2 or more finite amounts of substances are mix together (with different temperature) the final temperature is never equivalent to the initial temperature of any of the substances involved.
2. The substances meet at an equilibrium temperature.
3. Heat transfers from a higher temperature to a lower temperature.
Only choice (3) satisfies the conditions.
I believe the answer is C !
In general, if a reaction is spontaneous, the reactants possess more free energy than the products.
