Which statements describe the law of conservation of charge? check all that apply.

a. the total charge of the reactants and products must be equal.
b. the net charge of an isolated system remains constant.
c. the number of nucleons is constant.
d. the total mass in the reaction is constant.

The statements in accordance with the law of conservation of charge are:
A. The total charge of the reactants and products must be equal
B. The net charge of an isolated system remains constant

Both of these statements follow the law of conservation of charge which states that charge may neither be created nor destroyed, due to which the total charge in an isolated system (one in which charge can not move in or out of) remains constant.
