Question

Please answer these questions​

Answer 1

Explanation:

1. 3Fe+4H2O=Fe3O4+4H2
2. 3Ca+N2 = Ca3N2
3. Zn+2KOH = K2ZnO2+H2

5. 3PbO+2NH3 = 3Pb+3H2O+N2

6. 2Pb3O4 = 6PbO+O2

7. 4PbS+6O2 = 4PbO+4SO2

8. S+2H2SO4 = SO2+2H2O

9. MnO2+4HCl = MnCl2+2H2O+Cl2

Answer 2

1)3Fe+4H2O-------→Fe3O4+4H2

2) 3ca+N2-------→Ca3N2

3)Zn+2KOH--------→K2ZnO2+H2

4)Fe2O3+3CO---------→2Fe+3CO2

5)Pbo+2NH3---------→Pb+3H2+NO

I done upto here sorry because I have some important work...

I hope it's help you.............
