In 1977, Swedish chemist Carl Wilhelm Scheele first discovered and proved that hydrogen sulfide is a molecule that contains hydrogen and sulfur.Hydrogen sulfide uses mainly for the production of sulfur and sulfuric acid.

Hydrogen sulfide is a gaseous state substance, when it is going to dissolve in to water it will become a "Hydrosulfuric Acid". The basic structural formula of this acid is H2S, and into chemical science or chemistry this is well known and useful acid.

‏Hydrogen peroxide is a colorless, chemical compound with the formula H202. Surprisingly, it only contains one extra oxygen molecule than water. This extra oxygen molecule, however, creates a strong and powerful oxidizer that's capable of killing bacteria and viruses.

Use KHC8H4O4 as the formula for potassium hydrogen phthalate, KHC8H4O4- to represent the hydrogen phthalate ion and so forth. In the laboratory a gaseous compound of carbon and hydrogen contains 50% carbon by mass. The molar mass of the hydrogen carbon is 30.2g.
