Write the reaction equation: Ca- CaO- Ca (OH) 2- CaSo4- CaCl2

Ca-> CaO-> Ca (OH) 2-> CaSo4-> CaCl2
1) 2Ca + O2 ⟹ 2CaO (calcium, when interacting with oxygen, forms calcium oxide);
2) CaO + H20 ⟹ Ca (OH) 2 (calcium oxide, when reacted with water, forms calcium hydroxide);
3) Ca (OH) 2 + H2SO4 ⟹ CaSO4 + 2H2O (when sulfuric acid interacts with calcium hydroxide, we obtain calcium sulfate and water);
4) CaSO4 + BaCl2 ⟹ CaCl2 + BaSO4 (precipitate) (when calcium sulfate and barium chloride react, we get calcium chloride and barium sulfate).
