CHXI11:THE P-BLOCK ELEMENTS

316168 Which of the following statement(s) is/are incorrect for \(\mathrm{CO}_{2}\) ?
(i) In laboratory \(\mathrm{CO}_{2}\) is prepared by the action of dilute \(\mathrm{HCl}\) on calcium carbonate
(ii) Carbon dioxide is a poisonous gas
(iii) Increase in carbon dioxide content in atmosphere lead to increase in green house effect.
(iv) \(\mathrm{CO}_{2}\) as dry ice is used as a refrigerant for ice cream and frozen food.

316169 \(\mathrm{H}_{2} \mathrm{SO}_{4}\) is not used for preparation of \(\mathrm{CO}_{2}\) from marble chips because

1 It does not react
2 Huge amount of heat is evolved
3 The reaction is vigorous
4 Calcium sulphate is sparingly soluble and gets deposited on marble chips and stops the reaction.

316170 Supercritical \(\mathrm{CO}_{2}\) is used as

1 Dry ice
2 Fire fighting
3 A solvent for extraction of organic compounds from their natural sources
4 A highly inert medium for carrying out various reactions.
