Aluminum metal reacts with iron(II)sulfide to form aluminum sulfide and iron metal.What is the stoichiometric coefficient for aluminum when the chemical equation is balanced using the lowest whole-number stoichiometric coefficients?

Question

Quizplus · Accepted Answer

The balanced chemical equation for the reaction between aluminum metal (Al) and iron(II) sulfide (FeS) is:

2Al + 3FeS → Al2S3 + 3Fe

This equation shows that 2 moles of aluminum react with 3 moles of iron(II) sulfide to form 1 mole of aluminum sulfide and 3 moles of iron. Therefore, the stoichiometric coefficient for aluminum is 2. Choice B is the correct answer.

Aluminum Metal Reacts with Iron(II)sulfide to Form Aluminum Sulfide and Iron
