Two substances, A and B were made to react to form a third substance, A2B according to the following reaction 2A + B → A2B which of the following statements concerning this reaction are incorrect?- The product A2B shows the properties of substances A and B
- The product will always have a fixed composition
- The product so formed cannot be classified as a compound
- The product so formed is an element
(a) (i), (ii) and (iii)
(b) (ii), (iii) and (iv)
(c) (i), (iii) and (iv)
(d) (ii), (iii) and (iv)
Correct answer: (c) (i), (iii) and (iv)
Explanation: 2A + B → A2B
The product A2B is a new compound formed hence, it does not show the properties of A and B. The product formed is a compound and not an element. The composition of a compound is fixed.
