Question

elemental sulfur can bea formed through the combustion of hydrogen sulfide (found in methane gas) carve in equation; H2 S +O2----S + H2 4
tell how much sulfur is made from 250 grams of methane

Answer 1

You need to redo your typing job, especially for "carve", H2 S and H2 4. None of that makes sense to me. Also, I don't see methane anywhere in the equation and nothing that tells me the percent S in methane.

Answer 2

A 0.250 g sample of a gas occupies 0.100 L at a pressure of 2.50 atm and a temperature of 25.0ºC. What molar mass?
