Chemical processes store and release _____ in the bonds of molecules.
A: mass
B: matter
C: energy
D: atoms

Answer 1

Answer is: C: energy.

For example, balanced chemical reaction: 2Mg(s) + O₂(g) → 2MgO(s) + energy.

This is chemical process (chemical reaction), because new substance (magnesium oxide MgO) is formed, the atoms are rearranged and the reaction is followed by an energy change (exothermic reaction because energy is released).

Answer 2

If my memory serves me well, the correct answer is: Chemical processes store and release C: energy in the bonds of molecules.
