Answer 1

Heya !!!

here is your answer !!!

silver is black colour due to presence of A2S

when the Silver is react with hydrogen sulphide there is formation of silver sulphide which is black in colour with hydrogen gas.




when the AgCl is kept in sunthere is decomposition reaction take place and clorine gas will go into atmosphere !!


here is a reaction that show :-

Ag ( s ) + H2S -----------> AgS + H2 ( g )

▶ this process is also known as tarnishing of silver .

▶ in this process when the Silver is react with hydrogen sulphide in the presence of air then of black colour of Silver sulphide is deposit on metal silver.

hence , option number D is correct !!!

hope it helps you dear !!!

thanks !!!

have a good day !!
