A non-metal A is an important consituent of our food and forms two oxides B and C. Oxide B is toxic where as C causes global warming. To which group of Periodic table does A belong?

The non-metal A is an imporant constituent of our food and most of the fuels around us A forms two oxides B and C . The oxides B is poisonous whereas oxide C causes global warming. (a) Identify A,B and C (b) To which group of periodic table does A belong? (c) Name another element which is placed in the same group as A

A nonmetal 'X' is an important constituent of all living organisms and it forms two oxides Y and Z which are gases. Y is toxic while Z is responsible for global warming. Identify X, Y and Z.

To which group and period does the element 'c' belong ?

A non-metal A which is the largest constituent of air, when heated with H2 in 1 : 3 ratio in the presence of catalyst (Fe) gives a gas B. 0n heating with O_(2) it gives an oxide C. If this oxide is passed into water in the presence of air, it gives an acid D which acts as a strong oxidising agent. (a) Identify A, B, C and D. (b) To which group of the periodic table does this non-metal belongs?
