Differences and similarities in a mixture and compound

Mixture: matter than is composed of two or more substances that can be separated by physical means (ex; let's say you have a jar of red and blue marbles. this is a mixture. You can separate the colors with your hands (physical means.))

Compound: a substance in which two or more atoms are chemically combined in a fixed proportion (ex: water is a compound that consists of the element hydrogen and the element oxygen).
