Chemisty review on mass/matter and seperating mixtures
Chemistry
Mass and Energy
I -Energy- ability to do work/give of heat
-3 categories: radiant- uv, infrared, sun
Potential- stored
Kinetic- energy of motion
-Measuring energy- SI unit of Joule (j) or Calorie
-Calorimeter- device used to measure heat movements
-Fossil Fuels-coal, petroleum, natural gas
II- Chemical reactions - law of conservation of energy- matter cant be created nor
destroyed.
-Reactant- left, starting
-Product- right, end
-Endothermic reaction- absorb heat (candle)
-Exothermic reaction- releases heat (running)

III-Distillation- difference in boiling points, impure substance and heat, condenses, pure liquid, is collected in another flask
I -Types of mixtures:
1.Solution- homogeneous mixture made up of more than on material, can be in any phase (alloy, salt water) - clear transparent
2.Solute- gets dissolved
3.Solvent- does dissolving
II- Tyndall effect- Shine light through substance and it scatters. Scatters light by the particles in the mixtures.
1. Colloid- cloudy- homo (milk) (chocolate)
2. Suspension- hetero - salad
