Write a balanced chemical equation for each of the following reactions :
Action of dilute sulphuric acid on zinc sulphide.
Give reason for the following:
In the contact process, sulphur dioxide is dissolved in 98% sulphuric acid and not in water.
Give reason for the following:

How will you distinguish between conc. HCl and conc. H2SO4?
Some properties of sulphuric acid are listed below. Choose the property A, B, C or D which is responsible for the reaction (a) to (e). Some properties may be repeated.
A. Acid
B. Dehydrating agent
C. Non-volatile acid
D. Oxidizing agent
(a) \[\ce{C12H22O11 + nH2SO4 -> 12C + 11H2O + nH2SO4}\]
(b) \[\ce{S + 2H2SO4 -> 3SO2 + 2H2O}\]
(c) \[\ce{NaCl + 2H2SO4 -> NaHSO4 + HCl}\]
(d) \[\ce{CuO + 2H2SO4 -> CuSO4 + H2O}\]
(e) \[\ce{Na2CO3 + H2SO4 -> Na2SO4 + H2O + CO2}\]
Sulphuric acid is manufactured by the contact process.
Why H2SO4 is not obtained by directly reacting SO3 with water?
Concentrated sulphuric acid is both an oxidizing agent and a non-volatile acid. Write one equation. Each illustrates the above-mentioned properties of sulphuric acid.
