Cu → CuO → CuCl₂ → Cu(OH)₂ → CuSO₄

1. 2Cu + O₂ → 2CuO

2. CuO + 2HCl → CuCl₂ + H₂O

3. CuCl₂ + 2NaOH → Cu(OH)₂ ↓ + 2NaCl

4. Cu(OH)₂ + H₂SO₄ → CuSO₄ + 2H₂O

_______________________________

P → P₂O₅ → H₃PO₄ → Ca₃(PO₄)₂

1. 4P + 5O₂ → 2P₂O₅

2. P₂O₅ + 3H₂O → 2H₃PO₄

3. 2H₃PO₄ + 3Ca(OH)₂ → Ca₃(PO₄)₂ + 6H₂O
