Chapter 12, Problem 4STP

Interpretation Introduction

Interpretation: The balanced equation is to be stated.

Concept Introduction: According to the law of conservation of mass, the mass can neither be created nor be destroyed. Every reaction must be balanced. With the help of the balanced equation, the limiting reagent can be found and in accordance with it, the amount of product can be calculated.

Answer to Problem 4STP

The balanced reaction is ${\text{3T}}_{\text{2}}+{\text{Q}}_{\text{2}}\to 2{\text{T}}_{\text{3}}\text{Q}$ .

Explanation of Solution

The unbalanced reaction is given as follows:

  ${\text{T}}_{\text{2}}+{\text{Q}}_{\text{2}}\to {\text{T}}_{\text{3}}\text{Q}$

In the above reaction, the coefficient of 3 is placed before ${\text{T}}_{\text{2}}$ and 2 is placed before ${\text{T}}_{\text{3}}\text{Q}$ . The balanced reaction is given as follows:

  ${\text{3T}}_{\text{2}}+{\text{Q}}_{\text{2}}\to 2{\text{T}}_{\text{3}}\text{Q}$
