How many moles of copper are needed to react with sulfur to produce 0.25 moles of copper (i) sulfide according to the following reaction: 2 Cu + S = Cu2S

Answers

Answer:

0.5 mole

Explanation:

The equation for the reaction is given below:

2Cu + S —> Cu2S

We can calculate the mole of copper (Cu) needed to react with sulphur (S) to produce 0.25 mole of copper(I) sulfide (Cu2S) by doing the following:

From the balanced equation above,

2 moles of Cu reacted to produced 1 mole of Cu2S.

Therefore, Xmol of Cu will react to produce 0.25 mole of Cu2S i.e

Xmol of Cu = 2 x 0.25 = 0.5 mole

Therefore, 0.5 mole of copper (Cu) will react with sulphur (S) to produce 0.25 mole of copper(i)sulfide (Cu2S)
