Question

Which of the following is NOT a difference between a compound and a mixture?

1 Some mixtures are homogenous, while others are heterogeneous. All compounds are homogeneous.
2 Mixtures are homogeneous while compounds are heterogeneous.
3 No chemical bonding occurs between the components of a mixture. The properties of atoms and molecules are not changed when they become part of a mixture.
3 Mixtures can be separated by physical means, for example, straining, filtering, or evaporation. 4Compounds can only be separated into their constituent atoms by chemically breaking bonds.

Answer 1

2 Mixtures are homogeneous while compounds are heterogeneous.

Step-by-step explanation:

Mixtures are often described in chemistry as impure substances. They have the following properties:

• Their composition is indefinite and they contain two or more elements or compounds in any proportion by mass.
• The constituent of mixtures can be seperated into their components.
• They retain their identities i.e physical properties.
• Mixtures are heterogenous and can also be homogeneous. Homogeneous mixtures have their components in just a single phase. Heterogenous mixtures have their components in more than just a single phase.
