Interpretation: Raw eggs must be classified as a compound or mixture.
Concept Introduction: A compound that is made up of two or more chemical components that are not chemically linked with each other is said to be a mixture. The mixtures are classified based on the distribution of components:
- Homogenous mixture: A mixture is said to be homogenous when its composition is uniform throughout.
- Heterogenous mixture: A mixture is said to be heterogenous when its composition is not uniform throughout.
The chemical combination of two or more elements in a fixed proportion results in the formation of a compound.
Answer to Problem 72A
Heterogeneous mixture.
Explanation of Solution
In raw egg, the egg white and yolk are two different substances that can be seen easily and can be separated easily from one another. So, a raw egg can be classified as a heterogeneous mixture.
Interpretation: Ice must be classified as a compound or mixture.

Answer to Problem 72A
Compound.
Explanation of Solution
Ice is made up of the chemical combination of three atoms, two hydrogens and one oxygen. The chemical combination of these atoms makes up water and ice is the solid form of water and thus, it is classified as a compound.
Interpretation: Gasoline must be classified as a compound or mixture.
Concept Introduction: A compound that is made up of two or more chemical components that are not chemically linked with each other is said to be a mixture. The mixtures are classified based on the distribution of components:
- Homogenous mixture: A mixture is said to be homogenous when its composition is uniform throughout.
- Heterogenous mixture: A mixture is said to be heterogenous when its composition is not uniform throughout.
The chemical combination of two or more elements in a fixed proportion results in the formation of a compound.
Answer to Problem 72A
Homogeneous mixture.
Explanation of Solution
Gasoline is a mixture of several hydrocarbons present in a liquid state that form a single phase, which means the composition is the same throughout gasoline. Thus, it is classified as a homogeneous mixture.
Interpretation: Blood must be classified as a compound or mixture.

Answer to Problem 72A
Heterogeneous mixture.
Explanation of Solution
Blood includes platelets, plasma, and white and red blood cells. The blood can be easily separated into its component by using the pheresis process. Thus, it is classified as a heterogeneous mixture.
