last one .........what ....is..number of .....s2s04......​

Answer 1

Answer:

Sulfuric acid (American spelling) or sulphuric acid (British spelling), also known as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with molecular formula H2SO4. It is a colourless, odourless, and viscous liquid that is soluble in water and is synthesized in reactions that are highly exothermic.[6]

Answer 2

Answer:

+6

Explanation:

Oxidation number of H = +1

Oxidation number of O = -2

Let oxidation number of sulfur be X. Then ,

2 x (+1) + X + 4 x (-2) = 0

Solving we get,

+2 + X - 8 = 0

X = +6

Thus oxidation number of sulfur in H2so4 is +6
