A metal salt MX when exposed to light splits up to form metal M and a gas `X_(2)` . Metal M is used in making ornaments whereas gas `X_(2)` is used in making bleaching powder. The salt MX is itself used in black and white photography.
(a) What do you think metal M is ?
(b) What could be gas `X_(2)` ?
(c) Name the metal salt MX.
(d) Name any two salt solutions which on mixing together can produce a precipitate of salt MX.
(e) What type of chemical reaction takes place when salt MX is exposed to light ? Write the equation of the reaction.

A strip of metal X is dipped in the blue coloured salt solution YSO_(4) . After some time, a layer of metal Y from the salt solution is formed on the surface of metal strip. X metal Z is used in galvanisation whereas metal Y is used in making electric wires. Metal X and metal Y together form an alloy Z. (a) What could metal X be. (b) What could metal Y be ? (c) Name the metal salt YSO_(4) . (d) What type of chemical reaction takes place when metal X reacts with salt solution YSO_(4) ? Write the equation of the chemical reaction involved. (e) Name the alloy Z.
