i)I. Mistake: Ammonia is being collected using the wrong method
reason: Ammonia is less dense than air hence cannot be collected by downwards delivery
II. Mistake: The flask is not slanted
Reason: Condensed water will flow back to the hot flask making it crack.
ii) Calcium oxide
iii) When moist red litmus paper is put in ammonia gas it turns blue.
