(1) In the products formed, H2S is a gas, and KCl is a salt. The H2S will be escaped from the reaction mixture as it is gas. hence it is a gas evolution reaction (option 4).
(2) K is the ratio of products upon reactants, so a large value of K means a large amount of products. Hence the answer is option 3.
(3) Water is polar in nature. Hence non-polar substances will not be soluble in water. The non-polar substance given in the options is oil (option 1). Option 2&4 are salts they will be soluble in water. Option 3 is alcohol which is also miscible with water. So the answer is option 1, oil (non-polar)
PLEASE LET ME KNOW IF YOU ARE SATISFIED WITH THE ANSWER.
