Answer to Question #168742 in Inorganic Chemistry for Alex

Question #168742

Copper (II) sulfide reacts with oxygen gas to produce copper (II) oxide and sulfur dioxide. What is the balanced equation? If 100.0 g of copper (II) sulfide and 56.0 g of oxygen are available, what mass of copper (II) oxide is formed? Identify the limiting reactant. Include balanced equation, molar mass values, dimensional analysis, and limiting reactant.

We have the given reaction,



Given mass of copper sulfide = 100.0 g

Given mass of oxygen = 56.0 g of



Hence, we can conclude that is the limiting reagent in this reaction.


Mass of formed = 15.6g


Molar mass of Limiting reagent CuS = 159.16g/mol
