Question

From the below points, pick the ones which are applicable to a homogeneous mixture.
If your answer is 125, type that in.
Pick in order and not at random. Be very careful while choosing!

1. Uniform composition
2. Multiple phases
3. Chemically combined
4. Often mechanically separable
5. Single phase
6. Physical and chemical properties retained
7. Only chemical properties retained
8. Chemical properties retained, physical properties may be retained.

Your answer is ___

Answer 1

We know that a mixture is composed of different substances which are not combined chemically and individual physical properties are retained.
A homogeneous mixture is a mixture of a single phase and hence also with uniform composition throughout. This is what separates it from a heterogeneous mixture which has multiple phases.
A homogeneous mixture would have the chemical properties of its components retained as does any mixture but the physical properties are not retained. There is usually a deviation from those of the components. So, uniform composition - check. - 1
multiple phases - no
chemically combined - no
often mechanically separable - check - 4
single phase - check - 5
Physical and chemical properties retained - no
only chemical properties retained - check - 7
Chemical properties retained, physical properties may be retained. - no
