Question

Fe(s) +H2O(g) = Fe3O4 + H2(g)
MnO2 + HCL = MnCl2 + Cl2 + H2O
HNO3 + Ca(OH) 2 = Ca(NO3)2 + H2O

Balance. The chemical reaction

Answer 1

Answer:

The answer is in the attachment.

Answer 2

Answer:

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

MnO2 + 4HCl = MnCl2 + Cl2 + 2H2O

2HNO3 + Ca(OH)2 = Ca(NO3)2 + 2H2O

Explanation:

Aftrr balancing any equation we must check that whether the no. of elements/atoms are equal is reactant and product side.
