Question

balance the following equation H2+Cl2→HCl

Answer 1

H2+Cl2→2HCl we can get this by just looking at it

Answer 2

$H_{2} + Cl_{2}$  →  2 HCl

Why balancing chemical equation is important?

• Balancing chemical equations involves the addition of stoichiometric coefficients to the reactants and products so as to make the mass on both sides of the equation equal.

• This is important because a chemical equation must obey the law of conservation of mass and the law of constant proportions,
• According to the law of conservation of mass, mass can neither be created nor be destroyed in a chemical reaction. Similarly, the total mass of the elements or molecules present on the reactant side should be equal to the elements or molecules present on the product side.
