This equation is CaO + H2SO4 = CaSO4 + H2O.
A balanced equation MUST have EQUAL numbers of EACH type of atom on BOTH sides of the arrow.The balanced equation for the reaction magnesium chloride plus sulfuric acid is;MgCl2 + H2SO4 ------> MgSO4 + 2HCl.
CuO + H2SO4 --> CuSO4 + H2O
Simplified. 2NaOH + H2SO4 -> Na2SO4 + 2H2O
Mg(OH)2 + H2SO4 --> MgSO4 + 2H2O
This equation is CaO + H2SO4 = CaSO4 + H2O.
The equation is:MgO + H2SO4 = MgSO4 + H2O
