Question

Given the unbalanced reaction, Fe + S​ ​---​-> Fe​ S​ , how 8​ 2​ 3​

many moles of each reactant are needed ​to ​produce 1.50 moles of iron (III) sul​f​ide​? (balance equation first)

Answer 1

The answer to your question is 3 moles of Fe and 4.5 moles of S

Step-by-step explanation:

Data

moles of Fe = ?

moles of S = ?

moles of Fe₂S₃

Unbalanced chemical reaction

Fe + S ⇒ Fe₂S₃

Reactants Elements Products

1 Fe 2

1 S 3

Balanced chemical reaction

2Fe + 3S ⇒ Fe₂S₃

Reactants Elements Products

2 Fe 2

3 S 3

-Calculate the moles of each reactant

2 moles of Fe ------------------- 1 mol of Fe₂S₃

x -------------------- 1.5 moles Fe₂S₃

x = (1.5 x 2) / 1

x = 3 moles of Fe

-Calculate the moles of S

3 moles of S --------------------- 1 mol of Fe₂S₃

x --------------------- 1.5 moles of Fe₂S₃

x = (1.5 x 3) / 1

x = 4.5 moles of S
