1 Properties of H2SO4 are listed below. Choose the property A, B, C or D which is responsible for the reactions iloc Acid : Dehydrating agent C. Non-volatile acid D: Oxidizing agent 11 C12192011nH9504120 111120 + nH2SO4, ii] S + 2H, SO 4 3502 + 2H20, Nace+'|1,804 > NaHSO4 + HCl, iv! Cuo*+ H2SO4 → CuSO4 + H2O, → Na2SO4 + H2O + CO2​

Answer-

1)C12H22011+nH2S04->12C+11H20+nH2

SO4

In the above reactions,in reaction (I) is

sulphuric acid shows dehydrating property.

Il) S+2H2S04->3S02+2H20

In reaction (Il) Sulphuric acid interact as

oxidasing agent.

Ill) NaCItH2S04->NaSO4+HCl

In (Ill) acid acts as non-volatile acid.

IV) CUO+H2S04->CuSO4+H20

In reaction (IV) acid acts as acid property.

V)Na2CO3+H2S04->Na2S04+H20+CO2

In (V) it shows acid property with sodium

bicarbonate and give water.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >
