Question

Cl2 + KI → KCI + Iz what the balance?

Answer 1

Answer:

Cl₂ + 2KI → 2KCI + I₂

Explanation:

We are given;

• Unbalanced equation;

Cl₂ + KI → KCI + I₂

We are required to balance the equation;

First we need to understand what is a balanced equation?

• A balanced equation is an equation that has equal number of atoms of each elements on the side of reactants and that of the products.

Second; Why is it important to balance chemical equations?

• Chemical equations are balanced so as to obey the law of conservation of mass.
• According to the law of conservation of mass, the mass of products should be equivalent to the mass of reactants.

How do we balance equations?

• We balance chemical equations by putting appropriate coefficients on the reactants and products.

Therefore, in this case;

• The balanced equation  will be;

Cl₂ + 2KI → 2KCI + I₂
