c)
Reasons why excess hydrogen chloride gas is dissolved using the funnel arrangement are:

d)
When the reaction in the combustion tube is complete, the observation will be:

• The burning of hydrogen gas at the jet will stop.

e)

i) Here are the observations made in the table:

Solution of hydrogen chloride gas in:	Blue litmus paper	Marble chips
Water	Turns red	Effervescence/fizzing observed, gas produced
Methylbenzene	No change (remains blue)	No reaction/no effervescence
