When a green solid P was heated it turned into a black solid Q and a colourless gas X was released. On passing gas X, over heated carbon and another colourless gas Y was formed. Gas Y burned in oxygen to reform gas X.
Name gases X and Y.

When a green solid P was heated it turned into a black solid Q and a colourless gas X was released. On passing gas X, over heated carbon and another colourless gas Y was formed. Gas Y burned in oxygen to reform gas X. Identify P and Q.

When a green solid P was heated it turned into a black solid Q and a colourless gas X was released. On passing gas X, over heated carbon and another colourless gas Y was formed. Gas Y burned in oxygen to reform gas X. What will be be observed if gas X is bubbled into lime water ?

A gas X turns line water milky. The milkiness disappears if excess of 'X' is passed. Milkiness reappears on heating the colourless solution. The gas is

Passage - I : A yellow powder 'x' is burnt in a steam of Fluorine to obtain a colourless gas 'y' which is thermally stable and chemically inert its molecule has octahedral geometry another colourless gas 'z' with same constituent atoms as that of 'y' is obtained when sulphur dichloride is heated with sodium fluoride. It's molecule has trigonal bi-pyramidal geometry The colourless gas 'y' is

When Ethanoic acid is added to a solution of substance X, a colourless and odourless gas Y is liberated. The gas Y turns lime-water milky. The substance X is ____

A metal sulphide A gives gas B with rotten egg smell and a colourless sulphate C, when treated with dil H_2SO_4 . B reacts with K_2Cr_2O_7//H^+ to form D, a white grey element. D burns in oxygen to yield E a colourless gas. If B is added to E, it gives D and a colourless liquid, which turns anhydrous CuSO_4 blue. C gives precipitate with NH_(3(aq)) or NaOH, which dissolves in excess of NaOH

X reacts with dilute nitric acid to form laughing gas . What is X?
