Question

Elemental Sulfur can be formed through the combustion of Hydrogen Sulfide (found in Methane gas) give in equation H2 S +O--->S + H2 4
tell how much sulfur is made from 250 grams of methane

Answer 1

I think I responded to this question earlier and I THINK by the same poster but if not I apologize. At any rate, I can't answer the question
1. I don't know what H2 S is.
2. There is no such thing as O by itself.
3. What is H2 4?
4. Even if I knew the answers to 1-3, we still need to know the percent S in methane or some way to calculate it.

Answer 2

The real equation should be something like this:
H2S + O2 -> S + H2O
Balancing the equation:
2 H2S + O2 -> 2S + 2H2O
The question does not mention anything about methane, CH4.
Also, The sulfur in the equation (mistaken as methane, i suppose) is one of the product, not the reactant.
