Question

Which of the following describes a homogeneous mixture? (2 points) Question 18 options: 1) It can be separated by chemical means but not by physical means. 2) It cannot be separated by either chemical or physical means. 3) It can be separated by physical means and is uniform in composition. 4) It can be separated by physical means and is not uniform in composition.

Answer 1

It can be separated by physical means and is not uniform in composition.

Answer 2

Answer: Option (3) is the correct answer.

Explanation:

A mixture that consists of two or more substances mixed in uniform composition then it is known as a homogeneous mixture.

For example, NaCl dissolved in water is a homogeneous mixture.

There will be equal composition of NaCl and water. Therefore, we can obtain NaCl crystals from this solution by evaporating the water.

Hence, we can conclude that the statement it can be separated by physical means and is uniform in composition, describes a homogeneous mixture.
