Question

Which of the following is an example of a homogeneous mixture?

A. Bronze
B. Sand
C. Copper
D. Zinc

Answer 1

The correct answer is:

A. Bronze

Step-by-step explanation:

Bronze is an alloy consisting principally of copper, generally with about 12% tin and often with the extension of other metals and sometimes non-metals or metalloids such as arsenic, phosphorus or silicon.Both copper and tin are solid.

A homogeneous mixture is a solid, liquid, or gaseous mixture that has the same proportions of its components throughout any given sample. Conversely, a heterogeneous mixture has elements whose dimensions vary completely the sample. Water itself is an example of a homogeneous mixture. It often includes dissolved metals and gases, but these are removed throughout the water.

Answer 2

Homogeneous (in terms of Chemistry) means "in the same physical state"

For example if Nitrogen and Hydrogen reacted, and they were both gases, the reaction would be homogeneous.

Sand is a compound, so therefore not a mixture.

Copper and Zinc are both elements, so again, not a mixture.

Bronze is an alloy, a mixture of Copper and Tin. As Copper and Tin are both solid (metals), we can say this mixture is homogeneous.

The answer is (A) Bronze.
