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 concerning the species X, Y and P are correct?- P is a compound
- X and Y are compounds
- X and Y are elements
- 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)
Correct Answer: (d) (i), (iii) and (iv)
Explanation: When two elements combine in a chemical reaction to give a product, the product is a compound. The composition of a compound has a fixed ratio and its properties are different from the elements participating in the reaction.
