Question

1. How many moles of iron is needed to react with sulfur in order to produce 8.6 moles

Answer 1

Answer:

17.2 moles of Iron are required

Explanation:

Based on the chemical reaction:

2Fe + 3S → Fe₂S₃

2 moles of Fe react with 3 moles of S to produce 1 mole of Iron (III) sulfide

Assuming and excess of sulfur, if we want to obtain 8.6 moles of Fe₂S₃ are required:

8.6 moles Fe₂S₃ * (2 moles Fe / 1mol Fe₂S₃) =

17.2 moles of Iron are required
