Suppose all the grains in a sample of sand were exactly the same size. Could the sample still be a heterogeneous mixture? Explain your answer

Respuesta :

Yes, the sample will still be a heterogeneous mixture.

A mixture contains two or more substances in any proportion.

Mixtures are divided into two main groups:

  • Homogeneous mixtures: They are made up of constituents that are uniformly distributed through out the mixture.

This shows that a homogeneous mixture has only one single phase.

It is either in a solid or liquid or gaseous phase.

A typical example is air which contains a mixture of gases of the same phase.

  • Heterogeneous mixtures:They are made up of different constituents that have different compositions

This means that a heterogeneous mixture can contain constituents of different or the same phase but in different quantity.

A typical example is a mixture of  sand and grains. Both are of a solid phase but are combined together in different quantity even when the size of the grain is the same with the sand.

Therefore, the sample will still be a heterogeneous mixture.
