Question

Balance the chemical equation :-
(a) H2 + O2 ➡️ H2O
(b) Ca + H2O ➡️ Ca(OH)2 + H2
(c) Na + O2 ➡️ Na2O
(d) KClO3 ➡️ KCl + O2
(e) FeS + HCl ➡️ FeCl2 + HCl​

Answer 1

Answer:9

Explanation:

H2 + O2 ➡️ H2O

(b) Ca + H2O ➡️ Ca(OH)2 + H2

(c) Na + O2 ➡️ Na2O

(d) KClO3 ➡️ KCl + O2

(e) FeS + HCl ➡️ FeCl2 + HCl​=9

Answer 2

Answer:

1) 2H2 + O2 = 2H2O

2) Ca + 2H2O = Ca(OH)2 + H2

3) 4Na + O2 = 2Na2O

4) 2KClO3 = 2KCl + 3O2

5) FeS + HCl = FeCl2 + HCl. (This is not possible plz recheck the equation since S is missing in the product).
