Two chemical species X and Y combine together to form a product P which contains both X and Y, X + Y `to` P, X and Y cannot be broken down into simpler substances by simple chemical reaction. Which of the following cocerning the species X, Y and P are correct?
(i) P is a compound (ii) X and Y are compounds
(iii) X and Y are elements (iv) P has a fixed composition

A

(i), (ii) and (iii)

B

(i),(ii) and (iv)

C

(ii), (iii) and (iv)

D

(i),(iii) and (iv)

Text Solution

Verified by Experts

The correct Answer is:
D
In this reaction, X and Y can not be broken down into simpler substances by chemical reactions, therefore, X and Y are elements. A compound is a substance made up of two or more elements chemically combined in a fixed proportion by mass, therefore, P is a compound, having a fixed composition.
