Answer 1

Answer:

Answer 2

Z show same properties as that of X and Y is the answer. The properties can be found it will be subset properties of the element combined.

Answer - (Option D)

Explanation:

• These statements are unpredictable without knowing the mass of the mixtures.
• As given there are two elements X and Y. The ‘mass’ of the given elements are unknown.
• The ‘mass of the compound Z’ can only be determined if ‘the mass of X and Y’ are known.
• The properties of the Z will depend on the properties of X and Y and hence the statement.
