Verified step by step guidance1
Understand the definition of a mixture: A mixture consists of two or more substances combined physically, not chemically bonded.
Recall that mixtures do not have a fixed chemical formula because their composition can vary.
Recognize that mixtures can be either homogeneous (uniform composition) or heterogeneous (non-uniform composition), so uniformity is not guaranteed.
Note that components in a mixture retain their individual properties and are not chemically bonded together.
Identify that a key characteristic of mixtures is that their components can be separated by physical means, such as filtration, distillation, or decantation.
