2) H2O----→ H2 +O2

3) H2 + Cl2 -------→HCl

4)Na +O2 ------→Na2O

5) Na + Cl2 -----→ NaCl​

Answer 1

Answer:

1-add 2 to both the reactants

2-reactant will be 2h2o2

3- add 2 to product

5-add 2 to Na.

Answer 2

Answer:

Fe+2HCl-------->FeCl2+H2

2H2O------->2H2+O2

H2+Cl2----->2HCl

Na+Cl2------>NaCl2
