What gas CH4 OR H2S heavier?

H2S (hydrogen sulfide) is heavier than CH4 (methane) because the molar mass of sulfur (S) is greater than the molar mass of carbon (C). This difference in molar masses results in hydrogen sulfide being denser and therefore heavier than methane.


Is H2S the heaviest gas?

No, remember any element heated to a high enough temperature will form a gaseous phase for instance mercury vapour would be heavier than H2S.


Is h2s heavier than nitrogen?

Yes, hydrogen sulfide (H2S) is heavier than nitrogen (N2) because the molar mass of H2S (34.08 g/mol) is higher than that of N2 (28.02 g/mol). This means that per mole, H2S will have a greater mass than N2.


How can you make h2s?

Add an acid to Na2S.It will emit H2S.


Is H2S ironic or covalent?

H2S is a polar compound.It is not ionic.


What is the pH of a solution containing H2S?

The pH of a solution containing H2S would be acidic, as H2S is a weak acid. The exact pH value would depend on the concentration of H2S in the solution.


What is the fomula for hydrosulfuric acid?

Hydrosulfuric acid is H2S. H2S (aq) (H2SO4 is sulfuric acid). The acids with "hydro" at the start of their names are all derived from dissolved gases, e.g. hydrochloric acid is aqueous hydrogen chloride, hydrocyanic acid is aqueous hydrogen cyanide etc.


What is the state of h2s?
