Question

S-FeS-SO2-SO3-H2SO4-SO2

Answer 1

Ответ:

S + F = FeS

4FeS + 7O2 = 2Fe2O3 + 4SO2

2SO2 + O2 = 2SO3

SO3 + H2O = H2SO4

2H2SO4 + S = 3SO2 + 2H2O

Answer 2

It seems like you've provided a sequence of chemical compounds or reactions involving sulfur and its compounds. Let me break down the sequence for you:

1. S - This represents sulfur in its elemental form.
2. FeS - This represents iron(II) sulfide, a compound of iron and sulfur.
3. SO2 - This represents sulfur dioxide, a gas formed when sulfur burns in the presence of oxygen.
4. SO3 - This represents sulfur trioxide, a highly reactive compound often produced from the reaction of sulfur dioxide with oxygen.
5. H2SO4 - This is sulfuric acid, one of the most widely used and important industrial chemicals.
6. SO2 - Sulfur dioxide is mentioned again.

It appears to be a sequence of reactions or transformations involving sulfur and its compounds, possibly starting with elemental sulfur (S) and leading to the formation of sulfuric acid (H2SO4). If you have a specific question or need further information about a particular step in this sequence, please provide more details, and I'll be happy to help.
