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.
Identify A,B and C?

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?

(In T.S. anther, identify a, b and c)

A non-metal A which is the largest consituent of air, when heated with H_2 in 1:3 ratio in the presence of catalyst gives a gas B. on 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. Identify A,B,C and D.

An element A reacts with water to form a compound B which is used in white washing. The compound B on heating forms an oxide C which on treatment with watr gives back B. identify A, B and C and give the reacitons involved.

An alkali metal A gives a compound B on reacting with water. The compound B gives a soluble compound C on treatment with aluminium oxide. Identify A,B and C and give the reactions involved.

A metal, A which is used in thermite process, when heated with oxygen gives an oxide B, which is amphoteric in nature. Identify A and B. write down the reactions of oxide B with HCl and NaOH.

For all sets A, B and C, if A⊂ C and B ⊂ C,then A∪ B ⊂ C.

A part of Ellingham diagram for some metal oxides (based upon 1 mole of O_2 ) and carbon is shown. In figure A, B, C and D represent curves for metal oxides and a, b, c, d, e and f are temperatures. Answer the following : Will B oxide reduce metal oxide of A or C or both ?

Identify A,B,C and D in the given table: ,
