1)(NH4)2SO4 2)Cu(NO3)2 3)BaCl2 4)CuSO4 5)Pb(NO3)2 6)KI 7)AgNO3   8)Na3PO4   9)NaCl   10)HNO3 11)K2CO3

Answer 1

1.2NH3 (aq) +H2SO4-(aq)---> (NH₄)₂SO4

2.Cu(s) +2HNO3(aq)---> Cu(NO3)2 +2NO2(g) +2H2O(l)

3. Ba(OH)2 (aq) +2HCl (aq) ----> BaCl2 (aq)+2H2O (l)

4. Cu(S)+2 H2SO4(aq)---> CuSO4(aq)+ H2O(l)+SO2(g)

5. Pb (s)+ 2HNO3- (aq)--> Pb(NO3)2 (aq)+H2 (g)

6. 2K (s) +I2---> 2KI(aq)

7. 2Ag (s)+2HNO3-(aq) --> 2AgNO3 (aq)+H2 (g)

8. 3NaOH(aq)+ H3PO4(aq)---> Na3PO4(aq)+ 3H2O (l)

9. NaOH(aq)+ HCl (aq)----> NaCl (aq)+ H2O(l)

10. NO2(g) +H2O(l)----> HNO3 (aq)+NO(g)

11.2 KOH(aq) +H2CO3(aq) ---> K2CO3 (aq) +2H2O (l)
