Answer
(a) When sulphuric acid is added to a solution of barium chloride it reacts with barium chloride to form barium sulphate which is a white precipitate.
H2SO4 + BaCl2 ⟶ BaSO4↓ + 2HCl
When nitric acid is added to barium chloride, there is no reaction to form a precipitate because nitric acid does not contain sulphate ions. The solution remains clear.
(b) Unsaturated Hydrocarbons contain one or more double or triple bonds between carbon atoms. Examples include alkenes (with double bonds) and alkynes (with triple bonds). Saturated Hydrocarbons only have single bonds between carbon atoms.
