Answer 1

1) K₂O + SO₃ ---> K₂SO₄
2) Ag₂O + 2HNO₃ ---> 2AgNO₃ + H₂O

3) Mg +  2HNO₃ ---> Mg(NO₃)₂ + H₂
4) Mg(OH)₂ + 2HNO₃ ---> Mg(NO₃)₂ + 2H₂O

5) Mg(OH)₂ + N₂O₅ ---> Mg(NO₃)₂ + H₂O 

6) MgO + 2HNO₃ ---> Mg(NO₃)₂ + H₂O 
7. Fe₂O₃ + 3H₂SO₄ ---> Fe₂(SO₄)₃ + 3H₂O 

8) 2Fe(OH)₃ + 3SO₃ ---> Fe₂(SO₄)₃ + 3H₂O 

9) CaO + 2HCl ---> CaCl₂ + H₂O 
10) FeO + SO₃ ---> FeSO₄
11) Al(OH)₃ + H₃PO₄ ---> AlPO₄ + 3H₂O 
12) 2Na + S ---> Na₂S
13) PbO₂ +  2H₂SO₄  ---> Pb(SO₄)₂ + 2H₂O
