Cu -> CuO -> CuCl2 -> Cu(OH)2 -> CuO -> Cu -> CuSO4 -> Cu(OH)2 -> Cu(NO3)2 -> CuO

Question

Cu -> CuO -> CuCl2 -> Cu(OH)2 -> CuO -> Cu -> CuSO4 -> Cu(OH)2 -> Cu(NO3)2 -> CuO

Answer 1

Cu -> CuO -> CuCl2 -> Cu(OH)2 -> CuO -> Cu -> CuSO4 -> Cu(OH)2 -> Cu(NO3)2 -> CuO

1.2Cu + O2 = 2CuO

2.CuO + 2HCl= CuCl2 + H2O

3.Ca(OH)2 + CuCl2 → Cu(OH)2↓ + CaCl2

4.Cu(OH)2 = CuO + H2O

5.CuO + H2 = Cu + H2O

6.2H2SO4+ Cu = CuSO4 + SO2↑ + 2H2O
7.CuSO4 + 2NaOH = Cu(OH)2 + Na2SO4
8.2HNO3 + Cu(OH)2 = Cu(NO3)2 + 2H2O
9.2Cu(NO3)2 = 2CuO + 4NO2 + O2
