During a science lab activity, some sugar solution is taken in a test tube and a little amount of a substance is taken in powdered formed named as P. The test tube is allowed to stay still for some-time while the top is covered. When the top is removed from the cork, a characteristic smell is observed and a gas Z evolution also takes place. The gas evolved can extinguish a burning matchstick.1. Name the powdered substance P?a. Yeastb. Fungic. Algaed. None of the above2. Name the substance Y whose smell is obsereved ?a. Ammoniab.
