Question 3 -------->

a.Gold is used to make jewellery because of the attractiveness of its luster and because of its rarity. It also doesn't tarnish and doesn't react with air the way a metal like iron does. Therefore, gold is alloyed with other metals to make it stronger.

b.Sodium metals are kept in kerosene oil. ... Sodium is a very reactive metal. It is kept in kerosene to prevent it from coming in contact with oxygen and moisture. If this happens, it will react with the moisture present in air and form sodium hydroxide which is a highly exothermic reaction.

c.No gas is released when sulphur is added to dilute HCl. Since Cl is more reactive than S thus S cannot replace Chlorine to produce Hydrogen gas.

d.Corrosion is a natural process that converts a refined metal into a more chemically-stable form such as oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usually a metal) by chemical and/or electrochemical reaction with their environment.
