Solution

A homogenous mixtures, like a compound, are made of multiple components (substances). The difference is that a compound is made of two or more elements that are chemically combined while a homogeneous mixture is made of two or more substances that are not chemically combined. Though a homogeneous mixture is not chemically combined it may seem like it is. When light is shown upon a homogeneous mixture, its particles do not scatter light. In fact a mixture in and of itself, is the result of when two or more materials are put together and do not react to form a compound.

A compound is a substance formed when two or more chemical elements are chemically bonded together. In mixtures, the substances present are not chemically bonded together.
The type of bonds holding elements together in a compound can vary: two common types are covalent bonds and ionic bonds.

The elements in any compound are always present in fixed ratios.

Example - Pure water is a compound made from two elements - hydrogen and oxygen. The ratio of hydrogen to oxygen in water is always 2:1. Each molecule of water contains two hydrogen atoms bonded to a single oxygen atom.

A homogeneous mixture is a mixture of two or more compounds with compositions that are uniform or mixed together in such a way that they are indistinguishable from each other. A homogeneous mixture can be separated into two or more substances through physical or mechanical processes such as distillation, filtration, or sifting.
