Mixtures and Compounds

Types of Mixtures Two types of mixtures exist 1. Homogeneous Uniform in nature Cannot tell that it is a mixture by just looking at it Said to have 1 phase Called Solutions CANNOT USE FILTRATION TO SEPARATE IT!!!!!

Types of mixtures continued 2. Heterogeneous Not uniform in nature Can clearly see all of the parts of the mixture Said to have 2 or more phases depending on how many things are mixed together

How to Separate a Mixture 1. Evaporation 2. Boil 3. Use Filtration (For heterogeneous mixtures only!!!) 4. Distillation (Liquid Mixtures only) Separation by difference in boiling points) 5. Separation by density 6. Chromatography

Element Vs. Compound 1. Element Simplest form of matter Cannot be broken down any further Used as the building blocks for all things in nature

Compound Formed from the combination of 2 or more elements Will have unique properties that are different from the elements that created it Can be broken down into the component elements Formula is in a definite ratio
