please mark it as brainliest

and if you don't mind follow me

Answer 2

1. Zn(s) + 2AgNo3(aq) = Zn(No3)2(aq) + 2 Ag (s)

2. 3H2 (g) + N2 (g) = 2NH3 (g)

3. C (g) + O2 (g) = CO2

4. Ca(s) + 2H2O(l) = Ca(OH)2 (aq) + H2(g)

5. 2 N2 (g) + 5 O2 (g) = 2 N2O5 (g)

6. H2(g) + Cl2(g) = 2HCl(g)

7. BaCl2 (aq) + Na2So4 (aq) = BaSo4 (s) + 2NaCl

8. 2KBr (aq) + Bal2 (aq) = 2Kl(aq) + BaBr2 (s)

9. N2 (g) + O2 (g) = 2NO

10. CaO (s) + H2O (l) = Ca(OH)2 (aq)

11 . Mg(s) + 2HCl (aq) = MgCl2 (aq) + H2 (g)

12. H2 (g) + Cl2(g) = 2HCl (g)

13. Fe(s) + CuSO4 (aq) = FeSO4 (g) Cu (s)

14. Pb (s) + CuCl2 (aq) = PbCl2 (aq) + Cu (s)

15. 3Fe (s) + 4H2O (g) = Fe3O4 (s) 4H2 (g)

16. H2 (g) + O2 (g) = H2O (aq)

17. CH4 (g) + O2( g) = CO4 (g) + H2O(l)

18. 16 Al (s) + 3 S8 (s) = 8 Al2 O3 (s)

19. 2Al + N2 = 2AlN

20. H2 + Cl2 = 2 HCl
