Answer:

5.8 moles of copper are needed to react with sulfur to produce 2.9 moles of copper (I) sulfide.

Step-by-step explanation:

$2Cu+S\rightarrow Cu_2S$

Moles of copper(I) sufide = 2.9 mol

According to reaction, 1 mole of copper(I) sulfide is obtained from 2 moles of copper, then 2.9 moles of copper(I) sulfide will be obtained from :

(2)/(1)* 2.9 mol=5.8 mol copper

5.8 moles of copper are needed to react with sulfur to produce 2.9 moles of copper (I) sulfide.
