The total number of H atoms in the reactants is 6 (2 in H2 and 4 in H2O). Therefore, the total number of H atoms in the products must also be 6 to balance the equation. This means that 2 H atoms must be present in the second product formed.
So the answer is b) 2.
The equation is not balanced because the total number of atoms of each element in the reactants is not equal to the total number of atoms of each element in the products.
