Answer 1

2NaNo2+O2→ 2NaNO3

C2+o2→ 2Co

Cao+Co2→ Caco3

NH3+HCl→NH4Cl

2Al+3Br2→2AlBr3

2Na+Cl2→ 2Nacl

2H2 +O2→ 2H2O

2Hg+ o2→  2HgO

Fe+S → Fes

CaO + H2O → Ca(OH)2

2CO + O2 → 2CO2


I know only these eqns

Answer 2

Explanation:

01. C+ O2 = CO2

02. CaO + H2O = Ca(OH)2

03. 2CO + O2 = 2CO2

04. Ba + F2 = BaF2

05. Mg + CO2 = MgCO3

06. Fe + S = FeS

07. C + 2S = CS2

08. 4Fe + 3O2 = 2 FE2O3

09. 2H2 + O2 = 2H2O

10. H2 + O = H2O

11. 2H + O = H2O

12. C2 + O2 = 2CO

13. CaO + CO2 =CaCO3

14. NH3 + HCl = NH4CI

15. 2Al + 3Br2 = 2AlBr3

16. 2Hg + O2 = 2HgO

17. CaO + H2O = CA(OH)2

hope it helps
