In an activity to show that air is mainly a mixture of two gases (nitrogen and oxygen), the carbon dioxide produced by the burning of candle in air is absorbed by dissolving a substance X in water in the trough. The substance X is:
Important Questions on Air Around Us
The two gases A and B together make up about 99% of the air. Both these gases are colourless, tasteless and odourless. Gas A is very reactive whereas gas B is very unreactive. Gas A is necessary for the process of respiration in plants and animals whereas gas B is required by the plants to make their proteins.
What is (i) gas A, and (ii) gas B?
The two gases A and B together make up about of the air. Both these gases are colourless, tasteless and odourless. Gas A is very reactive whereas gas B is very unreactive. Gas A is necessary for the process of respiration in plants and animals whereas gas B is required by the plants to make their proteins.
What is the percentage of (i) gas A and (ii) gas B, in the air?
The two gases A and B together make up about of the air. Both these gases are colourless, tasteless and odourless. Gas A is very reactive whereas gas B is very unreactive. Gas A is necessary for the process of respiration in plants and animals whereas gas B is required by the plants to make their proteins.
Which gas, A or B, neither burns nor supports the process of combustion?

Which gas, A or B is filled in plastic bags containing potato chips to prevent their spoilage?
The gas X is colourless and odourless having a slightly sour taste which is a minor component of air. It is moderately soluble in water. This gas neither burns nor supports burning. It rather extinguishes a burning fire. If there were no gas X in air, there would be no animals or plants on the earth. Name the gas X.
