Answers
Answer:
CO2 is the correct answer
The given chemical reaction is of Fermentation of Yeast.
During the lab activity, some sugar solution is taken in a test tube and a little amount of Yeast is taken in powered form named as P. The tset tube is allowed to stay still for some time while the top is covered. When thhe top is removed from the Cork, a characteristics smell is observed of Ethanol produed during the reaction with the evolution of Carbon dioxide as Z. This gas can extinguish a burning matchstick.
i) Name the powdered substance P?
The powdered substance "P" is Yeast.
ii) Name the substance Y whose smell is observed?
While the reaction took place, the evolution of Ethanol as the substance can be smelled.
iii) Name the gas Z.
The gas Z is Carbon Dioxide.
iv) What is the process of conversion practiced in the above activity?
Fermentation is the process of conversion practiced in this activity. Fermentation is the process of breaking down of yeast into Alcohol or acid.
v) What type of respiration is observed in the above activity?
The Anaerobic Respiration is observed in this activity. Anaerobic respiration is the process of splitting up to sugar into energy during the absence of oxygen.
