The Balance Chemical equation is as follow,
2 Mg (s) + O₂(g) → 2 MgO(s)<span> + 72.3 kJ
According to this equation,
2 Moles of MgO formation involved = 72.3 kJ of Heat
So,
5 Moles of MgO formation will involve = X kJ of Heat
Solving for X,
X = (5 Moles </span>× 72.3 kJ) ÷ 2 Moles
X = 180.75 kJ of Heat
