Homogeneous mixtures can exist a) only in the gas phase. b) only in the solid phase. c) as liquid, solid, or gas. d) only in the liquid phase

Answer;

C) as liquid, solid, or gas.

Explanation;A mixture is a substance that is made up of two or more substances. A mixture may be either homogeneous or heterogeneous.A homogeneous mixture is a mixture in which the components are uniformly distributed. This means there is only one phase of matter, hence a homogeneous mixture can exist as a solid, gas or liquid.A heterogeneous mixture on the other hand is a type of mixture in which the components making the mixture are not uniform. A heterogeneous mixture contains more than one phases of matter. These types of mixtures may be either suspensions or colloids.
