Question

How many moles of copper Il sulfide can be produced from 2.8 moles of sulfur? Cu + S --> CuS​

Answer 1

Answer: 2.8 moles of copper (Il) sulfide
`(CuS)` will be produced from 2.8 moles of sulphur.

Step-by-step explanation:

The balanced chemical reaction is:

`Cu+S\rightarrow CuS`

According to stoichiometry :

1 mole of
`S` produce = 1 mole of copper (Il) sulfide
`(CuS)`

Thus 2.8 moles of
`S` will produce=
`(1)/(1)* 2.8=2.8moles` of copper (Il) sulfide
`(CuS)`

Thus 2.8 moles of copper (Il) sulfide
`(CuS)` will be produced from 2.8 moles of sulphur.
