Question
Chapter 20, Problem 4QAP
Interpretation Introduction
Interpretation:
To write the balanced chemical equation which represent the roasting of copper(I) sulfide to form “blister copper”.
Concept introduction:
In metallurgy, sulfide ores undergo roasting after their preliminary treatment. Roasting is the process of heating sulfide ores to higher temperatures in presence of air. The main goal of roasting is the purification of metal component present in the ore.A balanced chemical equation is an equation in which number of atoms of each of the elements is same in both the sides of the reaction equation.
