a)When silver nitrate comes in contact with skin, it is reduced to white color metallic silver.In most cases, a black stain appears due to formation of finely divided silver which has black color.

The black color is due to the decomposition of the Ag+ ion into Ag, silver. Silver nitrate will slowly decompose with the silver ion reverting to elemental silver. The microscopic particles of silver are so small that they absorb light instead of reflecting it, and so appear black, instead of silver....

Riemann's green is a green pigment ZnO.CoO, which is obtained by heating a mixture of zinc oxide and cobalt nitrate or by the reaction of cobalt nitrate with either  or zinc sulphate.

As we know that wave of sound is a mechanical wave and its speed is given by

v = (γRT/M)

whereas the wave of light is an electromagnetic wave and its speed is given by

c = (1/εoμo

So speed of sound depends on temperature of air but speed of light doesn't.
