Question

1) NaCI+HCI → 2) Na2S04+HCI → 3) Fе(ОН)3+НNО3 → 4) Zn+НNО3 → 5) CaO+HCI →

Answer 1

1)= NaCl+HCl
2)Na2SO4+2HCl=2NaCl+H2SO4
3)Fe(OH)3+3 HNO3=Fe(NO3)3+3H2O
4)Zn+ 2HNO3=Zn(NO3)2+H2
5)CaO+2HCl=CaCl2+H2O

Answer 2

1. NaCl + HCl ->
2. Na2SO4 + HCl ->
3. Fe(OH)3 + HNO3 ->
4. Zn + HNO3 ->
5. CaO + HCl ->
