Answer:

You will find that the lime water, in which you exhaled air turns milky earlier than the lime water in which air is passed through a pichkari. This indicates that amount of carbon-dioxide in the air that we breathe out is more

Air

It is a mixture of gases .

Its composition is :

Oxygen =21%

Nitrogen =78.09%

Carbon dioxide =0.03%

Argon =0.93%

small amounts of other gases

When exhaled air is passed through lime water , it turns lime water milky due to formation of calcium carbonate .
