volumes of H2S gas and oxygen are necessary to produce 14.2 L of sulfur dioxide gas? The balanced equation is:

Answer 1

Regardless of the volumes of H2S, O2, & SO2, the balanced equation is:

H2S + O2 --> SO2 + H2

Answer 2

Write the balanced equation:

H2S + O2 produces SO2 + H2

For all ideal gases, remember this: 1 mol of gas occupies a volume of 22.4 l

But in this problem, you do not need to convert to moles (by dividing everything by 22.4 l/mol). All you need to do is look at the relative mole ratio. Which is 1:1:1:1 as they are all gases.

So if you produce 14.2 l of SO2, that means you will need 14.2 l of H2S and also 14.2 l of O2.

(And by the way, you will also produce 14.2 l of H2).

So that's the answer!
