Question

1. Pb + FeSO4  PbSO4 + Fe
2. CaCO3  CaO + CO2
3. P4 + 3 O2  2 P2O3
4. 2 RbNO3 + BeF2  Be(NO3)2 + 2 RbF
5. AgNO3 + Cu  Cu(NO3)2 + 2 Ag
Balance these chemical equation

Answer 1

Answer:

2Pb+2FeSO4--->2PbSO4+2Fe

Answer 2

1.Pb+FeSO4=PbSO4+Fe

2.CaCO3=CaO+CO2

3.P4+3O2=2P2O3

4.2RbNO3+BeF2=Be(NO3)2+2RbF

5.2AgNO3+Cu=Cu(NO3)2+2Ag
