What is a homogeneous mixture?

A homogeneous mixture is a mixture in which the composition is uniform all over the mixture.

Molecules combined by atoms of two or more different molecules are compounds.

Solubility is a measure of how much of a solute can be dissolved in a particular solvent.

Atom can join together to form molecules.

A pure substance that can be broken down into two or more different pure substances by a chemical change is called a/an compound.

A pure substance that can't be broken down into two or more different pure substances by a chemical change is called an Element.

Mixtures are composed of two or more substances and can be separated by physical method.

The substance present in a smaller amount in a solution is called the solute.

The advantage of SI is that it is defined as only one unit for each quantity (type of measurement). This means that it is not required to convert from one unit to another (within the system) and there are no conversion factors for students to memorize.

A mixture is a combination of two or more substances which are not chemically combined together. That can be solids, liquids or gases.

Substances having the same phase form a mixture then the mixture is homogeneous and substances with different phases combine to give a mixture then that mixture is heterogeneous.

Examples of homogeneous mixtures: Solutions of salt and water.

Examples of heterogeneous mixtures: Sand and water as well as oil and water.
