Chapter 3, Problem 15QRT

(a)

Interpretation Introduction

Interpretation:

From the given reaction ${\text{X}}_{\text{2}}{\text{ + 2 Y}}_{\text{2}}\to {\text{ 2 XY}}_{\text{2}}$ the representation of the reactant has to be identified.

Concept introduction:

Balancing reaction:

Balanced reaction is a chemical reaction in which number of atoms for each element in the reaction and the total charge are same on both reactant side and the product side.

Steps in balancing the information

• Step 1: Write the unbalanced equation
• Step 2: Find the coefficient to balance the equation.
• The coefficient should be reduced to the smallest whole number.
