Answer: 2.8 moles of copper (Il) sulfide [tex](CuS)[/tex] will be produced from 2.8 moles of sulphur.
Explanation:
The balanced chemical reaction is:
[tex]Cu+S\rightarrow CuS[/tex]
According to stoichiometry :
1 mole of [tex]S[/tex] produce = 1 mole of copper (Il) sulfide [tex](CuS)[/tex]
Thus 2.8 moles of [tex]S[/tex] will produce=[tex]\frac{1}{1}\times 2.8=2.8moles[/tex] of copper (Il) sulfide [tex](CuS)[/tex]
Thus 2.8 moles of copper (Il) sulfide [tex](CuS)[/tex] will be produced from 2.8 moles of sulphur.
