Question

1. Mg + HCI
2. Mg + H2SO4
3. Na + HCl ->
4. CuO + HCl ->
5. CuO + H2SO4 →
6. NaOH + HCl ->
7. NaOH + H2SO4
8. CaCO3 + HCl ->
9. CaCO3 + H2SO4 ->

Answer 1

1. Mg + 2HCl = MgCl2 + H2
2. Mg + H2SO4 = MgSO4 + H2
3. 2Na + 2HCl = 2NaCl + H2
4. CuO + 2HCl = CuCl2 + H2O
5. CuO + H2SO4 = CuSO4 + H2O
6. NaOH + HCl = NaCl + H2O
7. 2NaOH + H2SO4 = Na2SO4 + 2H2O
8. CaCO3 + HCl = CaCl2 + H2O + CO2
9. CaCO3 + H2SO4 = CaSO4 + H2O + CO2
