(a)The diagram below shows incomplete set up of the laboratory preparation and collection of chlorine gas. Study it and answer the questions that follow.
(i)Complete the set up to show how dry chlorine gas may be collected.
(ii) The equation for the redox reaction that takes place is
#MnO_2#(s)+4 HCL(aq)→#MnCl_2#(aq)+#2H_2O#(l)+#Cl_2# (g)
Explain, using oxidation numbers, which species is reduced.
(iii)What is the purpose of water in flask L?
(b)Study the diagram below and answer the questions that follow.
When some hydrogen chloride gas is allowed into water and the mixture stirred, the bulb lights and gases X and Y are formed.
(i) Name: gas X ,gas Y
(ii) Explain why the bulb does not light before the hydrogen chloride gas is let into water.
(iii) Explain using equations why the volume of gas X is less than that of gas Y
