Elemental Sulfur can be formed through the combustion of Hydrogen Sulfide (found in Methane gas) give in equation H2S+O--->S + H2 4
tell how much sulfur is made from 250 grams of methane
2 H2S + O2---->2S +2 H2O
s=32
The equation helps a LITTLE. In response to what I presume is your clarification to the earlier post, I quote from the above question, "tell how much sulfur is made from 250 grams of METHANE" and we can't answer that without some indication of how much S is in CH4.
There isn't enough information to answer the question. The equations you have listed have no CH4 in them so without knowing percent S in CH4 (or some way to calculate it) the 250 g CH4 means nothing because we can't convert that into grams S.
To calculate how much sulfur is made from 250 grams of methane, we first need to determine the molar mass of methane and the molar mass of sulfur.
1. Molar mass of methane (CH4):
Carbon (C) has a molar mass of 12.01 g/mol
Hydrogen (H) has a molar mass of 1.01 g/mol
Total molar mass of methane = (12.01 g/mol x 1) + (1.01 g/mol x 4)
= 12.01 g/mol + 4.04 g/mol
≈ 16.05 g/mol
2. The balanced chemical equation for the formation of sulfur is:
2 H2S + O2 → 2S + 2H2O
According to the equation, the ratio of methane to sulfur is 2:2. This means that 2 moles of methane will produce 2 moles of sulfur.
3. Calculate the number of moles of methane in 250 grams:
Number of moles = Mass / Molar mass
Number of moles of methane = 250 g / 16.05 g/mol
≈ 15.56 mol
4. Calculate the number of moles of sulfur produced:
Since the ratio of methane to sulfur is 2:2, the number of moles of sulfur produced is the same as the number of moles of methane, which is 15.56 mol.
5. Convert moles of sulfur to grams:
Mass = Number of moles x Molar mass of sulfur
Mass of sulfur = 15.56 mol x 32.06 g/mol (molar mass of sulfur)
≈ 498.67 g
Therefore, approximately 498.67 grams of sulfur will be formed from 250 grams of methane.
