Given the law of conservation of energy, what best explains why heat may be absorbed during a chemical reaction?

a. the energy of the reactants is less than the energy of the products.

b. chemical reactions absorb as much energy from the surroundings as they release.

c. the products of a chemical reaction have a higher temperature than the reactants.

d. chemical reactions require kinetic energy because the reactants contain potential energy.

it's filtration, but this is an assumption so my apologies if i got this

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.
