Chapter 4, Problem 11PS

Interpretation Introduction

Interpretation:

The limiting reactant and the mass of ${\text{Na}}_{\text{2}}\text{S}$ produced in the given reaction have to be determined.

Concept Introduction:

• Limiting reagent: limiting reagent is a reactant, which consumes completely in the chemical reaction. The quantity of the product depends on this limiting reagent, it can be determined with the help of balanced chemical equation for the reaction.
• For chemical reaction balanced chemical reaction equation written in accordance with the Law of conservation of mass.
• Law of conservation of mass states that for a reaction total mass of the reactant and product must be equal.
