✔ 最佳答案
1. Mg(HCO3)2 (aq) + 2 HNO3 (aq) → Mg(NO3)2 (aq) + 2 CO2 (g) + 2 H2O (l)ionic : H+ (aq) + HCO3- (aq) → CO2 (g) + H2O (l)
2. CuO (s) + 2 HNO3 (aq) → Cu(NO3)2 (aq) + H2O (l)
ionic : 2H+ (aq) + CuO (s) → Cu2+ (aq) + H2O (l)
3. 2 Fe(OH)3 (s) + 3 H2SO4 (aq) → Fe2(SO4)3 (aq) + 6 H2O (l)
ionic : 3 H+ (aq) + Fe(OH)3 (s) → Fe3+ (aq) + 3H2O (l)
