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 …showed first 75 words of 198 total…

…showed last 75 words of 198 total…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
