Question

State two reasons for supposing that the brass is a mixture and not a compound

Answer 1

Brass is an alloy of Zn &Cu.

Brass is a mixture and not a compound because in compound the elements should be in definite proportions and the elements are chemically bonded to each other.

Whereas in brass the two elements Zn & Cu are not in definite proportions (they can mix in any ratio) & there is no chemical bonding between them.
