Chapter 11.1, Problem 8LC

Interpretation Introduction

Interpretation: To determine the step to writing a balanced chemical equation.

Concept Introduction: The type of chemical reaction in which the count of reactant will be identical to a count of product is referred to as a balanced chemical reaction.

Answer to Problem 8LC

There are a few steps to writing a balanced chemical equation.

Step 1: First write the reactant and product.

Step 2: Determine the atom which is unbalanced on both the reactant side as well as product side.

Step 3: Determine the coefficient to balance the reaction.

Step 4: Multiply those terms with that unbalanced molecule.

Explanation of Solution

There are a few steps to writing a balanced chemical equation.

Step 1: First write the reactant and product.

Step 2: Determine the atom which is unbalanced on both the reactant side as well as product side.

Step 3: Determine the coefficient to balance the reaction.

Step 4: Multiply those terms with that unbalanced molecule.

For example,

The unbalanced chemical reaction is:

  ${\text{H}}_{\text{2}}{\text{+O}}_{\text{2}}\to {\text{H}}_{\text{2}}\text{O}$

Step 1:

The count of a hydrogen atom on the reactant side 2.

The count of an oxygen atom on the reactant side is 2.

The count of a hydrogen atom on the product side is 2.

The count of an oxygen atom on the product side is 1.

Step 2: It is found that the oxygen atom is unbalanced in the reaction.

Step 3: The water molecule and hydrogen molecule are multiplied by 2.

Step 4: The balanced chemical equation will be:

  ${\text{2H}}_{\text{2}}{\text{+O}}_{\text{2}}\to 2{\text{H}}_{\text{2}}\text{O}$
