Answer 1

1/ 2Al(OH)3 --> Al2O3 + 3H2O

2/ Cu(OH)2 + H2So4 --> CuSo4 + 2H2O

3/ P2O5 + 6NaOH --> 2Na3PO4 + 3H2O

4/ AgNo3 + NaCl --> NaNo3 + AgCl

5/ FeCl2 + 2NaOH --> Fe(OH)2 + NaCl

6/ CuO + 2HCl --> 2H2O + CuCl2

7/ CuSO4 + 2NaOH --> Cu(OH)2 + Na2SO4

8/ Ca(OH)2 + H2SO4 --> CaSO4 + 2H2O

Answer 4

1/ 2Al(OH)₃ -> Al₂O₃+ 3H₂O

2/Cu(OH)₂ + H₂SO₄ ->CuSO₄ + 2H₂O

3/ P₂O₅ + 6NaOH -> 2Na₃PO₄ + 3 H₂O

4/AgNO₃ + NaCl -> NaNO₃ +AgCl\(\downarrow\)

5/FeCl₂ + 2NaOH => Fe(OH)₂ \(\downarrow\)+ 2NaCl

6/CuO + 2HCl => CuCl₂ + H₂O

7/ CuSO₄ + 2NaOH => Cu(OH)₂\(\downarrow\)+ Na₂SO₄

8/ Ca(OH)₂ + H₂SO₄ => CaSO₄ + 2H₂O
