▶️Mg + H2SO4 → H2 + MgSO4

▶️MgO + H2SO4 → MgSO4 + H2O

▶️MgCO3 + H2SO4 → MgSO4 + CO2 + H2O

Metal, metal oxide and metal carbonate reacts with acids to produce salts. When you want magnesium sulfate salts in lab use magnesium oxide and magnesium carbonate to prepare magnesium sulfate salts, because magnesium reacts with sulfuric acids to produce hydrogen gas and that is very dangerous because it explode easily.
