Interpretation Introduction

Interpretation:

The mass of limestone that is required to remove all the sulfur dioxide formed by the combustion of $8.5\times {10}^4\text{ kg}$ of coal that is $0.33\text{ mass \%}$ sulphur is to be determined.

Concept introduction:

Decomposition redox reactions are the reactions in which one compound decomposed to form one or more product. The reaction has at least one of the product in element form. Decomposition redox reactions can be further classified as thermal decomposition and electrolytic decomposition. In thermal decomposition, heat is employed for the decomposition reaction while in electrolytic decomposition electrical energy is employed for the decomposition reaction. The general representation of decomposition redox reaction is:

$\text{Z}\to \mathrm{X}+\mathrm{Y}$

Combustion reaction is those reaction in which reactant is reacted with molecular oxygen to form the product. Heat is released and the energy is produced in the reaction. Molecular oxygen is employed as an oxidizing agent in these reactions.
