Account for the following:
`CO_2` turns the lime water milky. On passing `CO_2` in excess, milkiness diappears.

Account for the following: CO_2 is linear but SO_2 is angular.

On passing CO_2 through lime water, milkiness appears. On further passing CO_2 , milkiness disappears. What is the Chemistry behind it?

When CO_2 is passed through lime water it turns milky. On passing excess of CO_2 , the milky colour disappears. Give the chemical reactions involved in the processes.

Give reasons for the following: CO_2 is a gas whereas SiO_2 is a solid.

Calculate the molar mass of CO_2 .

On passing CO_2 through clear lime water, it turns milky. What happens when more C O_2 is passed to the milky solution? Why?

On passing CO_2 through clear lime water, it turns milky. What is the reaction in the above case?
