The answer is (2) gains 12 moles of electrons. In every chemical reaction, the electrons will not be destroyed or created, it will only transfer. So the Al loses electrons, the oxygen needs to gain the same amount of electrons.

To do a balancing to result to a balanced equation, we do elemental balance from each side of the equation. Hence we do separate balances for H, P, O and Ca. In this case, the final balanced equation after balancing elementally is <span>3 Ca(OH)2(aq) + 2 H3Po4(aq) = 6 H2O(l) + Ca3(Po4)2(s)</span>
