Chapter U4, Problem 1STP

Interpretation Introduction

Interpretation:

The description of the given reaction needs to be identified.

Concept introduction:

A chemical equation is representation of a chemical reaction in the form of formulae and symbols of molecules and compounds involved. Here, the reactants are present on the left side of the reaction arrow and the products are on the right-hand side.

Answer to Problem 1STP

The option (C) is correct.

Explanation of Solution

The chemical reaction is as follows:

$\begin{array}{l}{\text{K}}_{\text{2}}{\text{CO}}_{\text{3}}{\text{(aq) + Mg(NO}}_{\text{3}}{\text{)}}_{\text{2}}\text{(aq)}\to {\text{2KNO}}_{\text{3}}{\text{(aq) + MgCO}}_{\text{3}}\text{(s)}\\ \text{potassium magnesium potassium magnesium}\\ \text{carbonate nitrate nitrate carbonate}\end{array}$

The description of the above reaction is solution of potassium carbonate and magnesium nitrate (both are in aqueous medium) reacts to form potassium nitrate and solid magnesium carbonate.

So, option (C) is correct.
