(A) X = Fe, Y = Fe,og (B) X = Ag, Y = Ag S (C) X = Cu, Y = Cuo (D) X = Al Y = ALO,​

Answer 1

Answer:

A)

Explanation:

An element X exposure to (H2O+O2) moist air,forms a reddish brown and a new compound y is formed.

Fe+H2O+O2⟶Fe2O3

This Fe2O3 is the reddish brown compound which is called rust.

So,X→Fe

Y→Fe2O3
