Write a balanced equation for the following reaction: copper(I) sulfide reacts with aluminum metal to form copper metal and aluminum sulfide

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be the same on the reactant and product sides. Thus chemical equations are balanced.

The skeletal equation is:

The balanced equation for a single displacement reaction is:

Thus the coefficient for aluminum when the chemical equation is balanced is 2.
