Answer 1

Answer:

(ii) is correct

Explanation:

The option (ii) is correct

In (i) , it says that the compound has properties of A and B. But we know that the compound formed slways has different properties from its parent elements.

The (ii) corresponds with the law of constant proportions, which is a universal law.

The (iii) is incorrect because 2 different elements toghether make a new compound which is entirely different from them

The (iv) is incorrecf as the compound is formed from 2 elements

Thus , option (ii) is the answer

Answer 2

Answer:

(ii) the product will always have a fixed composition.

reason for wrong statements:

(1) first statement is wrong because of product always has different properties than that of the reactants in a reaction.

(3) third statement is wrong because your a and b combine to form product a2b hence a2b is a compound.

(4) thought statement is wrong because here is the product formed which two elements a and b handset is a compound not an element because in an element only one type of atoms are present.

hence only 2 is correct

Reason: the proportion of composition of two elements in a compound is decided by the valency of the compounds. as the valencies of the elements a and b will never change .hence the composition will also never change

hope it helps you mate
