Question

Balance the following chemical equation.
Fe(s) +H2O(g) = Fe3O4 + H2(g)
MnO2 + HCL = MnCl2 + Cl2 + H2O
HNO3 + Ca(OH)2 = Ca(NO3)2 + H2O

Answer 1

Answer:

Explanation:

3Fe + 4H2O = Fe3O4 + 4H2

MnO2 + 4HCl = MnCl2 + Cl2 + 2H2O

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

Answer 2

Answer:  

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

MnO2 + 4HCl = MnCl2 + Cl2 + 2H2O

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

Explanation:

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