Question

An element X does not react with dilute acid to evolve hydrogen gas But produces an oxide XO on heating in air. This oxide XO is basic in nature and reacts with dilute HCl to form salt and water. The element X gets covered by a greenish layer when exposed to moist air. Identify element X, and the greenish layer formed on exposure to moist air

Answer 1

Explanation:

the element X will be copper because it is less reactive than hydrogen so it doesn't react with any dilute acid and when we heat copper then it will react to oxygen present in atmosphere and form copper oxide .
