2. In what part of an atom can protons be found? a. Inside the electrons

b. Inside the neutrons

C. Inside the atomic nucleus

d. Inside the electron shells

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
