Which formula for sulfuric acid is written correctly to show one sulfur atom, two hydrogen atoms, and four oxygen atoms?

Formula for sulfuric acid is H2SO4

Explanation:

Sulfuric acid is highly concentrated acid. It is known as king of chemicals. It is used in making of fertilizers, paints, dyes, detergents, etc.

H2SO4 is made in laboratory in different steps from burning of sulfur and oxygen. The sulfur is burned with air and oxygen is combined with it to form sulfur dioxide ( SO2).

Then SO2 is again mixed with oxygen in the presence of catalyst vanadium. It forms sulfur trioxide ( SO3). The sulfur trioxide is allowed to absorbed in water. The mixing of SO3 and H2O forms the sulfuric acid ( H2SO4).

It is highly concentrated and its dilution is decreased to some extent for selling.
