The sum of the masses of the reactants must equal the sum of the masses of the products; as required by
the Principle of Conservation of Mass.
Answer:
chemical cells that produce an electrical current
Explanation:
lead acid battery is a type of chemical cell, that discharges to produce electrical current.
lead acid battery uses lead peroxide for the conversion of the chemical energy into electrical power when it is discharging. It is also rechargeable, that is, it can convert electrical energy back to chemical energy during charging.
Thus, a discharging lead acid battery is best described as a chemical cells that produce an electrical current
No atoms are lost or made during the chemical reaction so the total mass of the products is equal to the total mass of the reactants. In an atom, protons and neutrons contribute to the mass and since the number of them doesn’t change, the mass doesn’t either.
