Example Questions
Example Question #1 : Atomic Structure And Properties
Which of the following mixtures is not a homogeneous mixture:
A table salt solution
Wine
Oil and vinegar
Tea
Coffee
Oil and vinegar
A homogeneous mixture is a uniform mixture of two or more components that appears uniform throughout. The oil and vinegar mixture would not appear uniform, and thus is a heterogeneous mixture.
Example Question #1 : Composition Of Mixtures
Which of the following is a heterogeneous mixture.
All of the above
Motor oil
Orange juice with no pulp
Gasoline
Oatmeal chocolate chip cookie
Oatmeal chocolate chip cookie
A heterogeneous mixture is a mixture of two or more components that do not appears uniform throughout. The oatmeal chocolate chip cookie mixture would not appear uniform, and thus is a heterogeneous mixture.
Example Question #1 : Atomic Structure And Properties
Which of the following are mixtures
All of the above
b and c
Distilled water
Reeses Peanut butter cup
Top soil
b and c
A mixture contains two or more different substances. Distilled water only contains liquid water, and is not a mixture.
Example Question #2 : Atomic Structure And Properties
What differentiates a homogeneous mixture from a pure substance?
The composition of a pure substance is fixed.
A pure substance can be separated into elements by physical means.
A mixture has a defined composition.
A pure substance is always a compound while mixtures can be elements or compounds.
A homogeneous mixture is uniform throughout.
The composition of a pure substance is fixed.
A heterogeneous mixture is a mixture of two or more components that do not appears uniform throughout. A pure substance contains only one component that has a fixed composition.
Example Question #2 : Atomic Structure And Properties
A slice of watermelon would best be described as?
None of the above
A homogeneous mixture of compounds
A pure compound
A heterogeneous mixture of elements and compounds
A heterogeneous mixture of compounds
A heterogeneous mixture of elements and compounds
A heterogeneous mixture is a mixture of two or more components that do not appears uniform throughout, but contains components that are elemental (single atom type) and compounds (contain two or more different elements).
