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 was no gas X in air, there would be no plants and animals on the earth.
a) Name the gas X
b) What is the percentage of gas X in air?
c) Why is gas X very important for the existence of all life?
Dear Student

Ans b) Carbon dioxide occupies about 0.04% by volume in air.
Ans c) Carbon dioxide plays an important role in sustaining life on Earth.
•It is one of the raw materials of Photosynthesis.
