Question

Запишите уравнения возможных реакций. (а) СаО + CuCl2 (b) Mg + HCI - (c) KOH+H2SO4 (d) KOH + FeC13 + (e) Cu(OH)2= (f) Zn (OH), + H2SO4​

Answer 1

Mg + 2HCl = MgCl2 + H2

KOH + H2SO4 = KHSO4 + H2O

Cu(OH)2 (t)= CuO + H2O

Zn(OH)2 + H2SO4 = ZnSO4 + 2H2O

Answer 2

(a) CaO + CuCl2 → CaCl2 + CuO (b) Mg + HCl → MgCl2 + H2 (c) 2 KOH + H2SO4 → K2SO4 + 2 H2O (d) 3 KOH + FeCl3 → 3 KCl + Fe(OH)3 (e) Cu(OH)2 → CuO + H2O (f) Zn(OH)2 + H2SO4 → ZnSO4 + 2 H2O
