In an exothermic reaction, the energy stored in the chemical bonds of the reactants is: (A) less than the energy stored in the bonds of the products.
(B) equal to the total amount of energy released.
(C) equal to the energy stored in the bonds of the products.
(D) greater than the energy stored in the bonds of the products.
My teacher said that it was A because of the formula to calculate bond enthalpies. However, when I search up this problem, everyone says that D is right. Which one is it?

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
