Question

Please assist with following question Which of the following statements is correct?A. A heterogeneous mixture is also known as a solution.B. A pure substance may be separated by filtration or distillation into two or more components.C.A heterogeneous mixture is composed of two or more substances in the same phase.D. The composition is uniform throughout a homogeneous mixture.

Answer 1

In this question we have the concept of solutions and mixtures, let's analyze each option in order to find the one that best fits with reality:

A. Heterogeneous mixtures and solutions aren't the same thing, a mixture is when you have two or more compounds mixed together in a container, and a mixture can be heteregenous (which will form two or more phases), or homogeneous (which will be uniform throughout the mixture), and a solution will be the same as a homogeneous mixture.

B. A pure substance will not be separated by any method, since there is nothing the separate, it is all the same substance

C. As I said in letter A, a heteregeneous mixture will not have the same phase, but it will have different phases

D. The composition of a homogeneous mixture will be uniform, just a as a solution

The correct one will be letter D
