Question

Two chemical species X and Y combine together to form a product P which contains both X and Y. X+Y→ P X and Y cannot be broken down into simpler substances by simple chemical reactions. Which of the following statements concerning the species X, Y and P are correct? The statements are as follows:

i. P is a compound. ii. X and Y are compound. iii. X and Y are elements. iv. P has a fixed composition. Now choose the correct answer: a. (i), (ii) and (iii) b. (i), (ii) and (iv) c. (ii), (iii) and (iv) d. (i), (iii) and (iv)

Answer 1

Answer:

(d) (i),(iii) and (iv)

Explanation:

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.

So the correct answer is d

Answer 2

Answer:

option d is the answer.
