5. Identifying the limiting reagent: Given the reaction 2Cu + S → Cu2S, if you had 3 moles of both Cu and S, which would you run out of first?

Answers

The reaction is 2Cu + S → Cu2SSo as per balanced given reaction we need one mole of sulphur over two moles of copperOrTo react with one mole of sulphur we need two moles of copperThus we can say that the mole ration required for complete reaction will beCu : S = 2 : 1As per the given problem the moles of each Cu and S are 3 molesThus for each three moles of given sulphur we need six moles of Cu to give three moles of Cu2SHowever we have only three moles of copper availableSo the limiting reagent is copper It is going to decide the actual yield of reaction The three moles of Copper will get completely utilized and only 1.5 moles of S will be used in the reaction making S an excess reagentThe moles of S left will be = 1.5 molesmoles of Cu2S formed = 1.5 moles
