Question

c) Balance the following equations: 1. Fe + H20 - Fe304 + H2 2. Ca + N2 - CasN2 3. Zn + KOH KÖZnO2 + H2 4. Fe2O3 + CO . Fe + CO2 5. PbO + NH3 - Pb + H2O + N2​

Answer 1

Answer:

Balancing chemical equations involves the addition of stoichiometric coefficients to the reactants and products. This is important because a chemical equation must obey the law of conservation of mass and the law of constant proportions, i.e. the same number of atoms of each element must exist on the reactant side and the product side of the equation.

The chemical reaction is given as

Fe + H2O → Fe3O4+ H2

The balanced chemical equation can be written as

3Fe + 4H2O → Fe3O4 + 4H2
