Ca → CaO → Ca (OH) 2 → CaCl2 → CaSO4:
1) 2Ca + O2 → 2CaO (calcium, oxygen, calcium oxide; compound reaction);
2) CaO + H2O → Ca (OH) 2 ↓ (calcium oxide, water, calcium hydroxide; compound reaction);
3) Ca (OH) 2 ↓ + 2HCl → CaCl2 + 2H2O (calcium hydroxide, hydrochloric acid, calcium chloride, water; exchange reaction);
4) CaCl2 + H2SO4 → CaSO4 ↓ + 2HCl ↓ (calcium chloride, sulfate acid, calcium sulfate, hydrochloric acid).
