#1: what is the difference between an exothermic and an endothermic reaction?

a. endothermic reactions release heat.

b. there are no changes in heat during either reaction.

c. exothermic reactions absorb heat.

d. endothermic reactions absorb heat.

The best response for the endothermic reaction would be D. Endothermic reactions absorb heat. Exothermic reactions release heat.

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.
