If 3.0 moles h2s and 1.0 mole so2 react according to the following equation, how many moles of water will form? reaction: 2h2s + so2 → 3s + 2h2o

 2 moles of will be formed.

Explanation: Reaction in the given question is :

Number of moles of = 1 mole

Number of moles of = 3 moles

Here, the excess reagent is because its number of moles are more and is the limiting reagent as its number of moles are less.

So, the amount of produced will depend on the the amount of used.

By stoichiometry, one molecule of produces 2 molecules of .

Therefore, 1 mole of will produce 2 moles of .
