Mixture Made of two or more substances- elements, compounds or both- that are together in the same place but are not chemically combined.
Heterogeneous Mixture You can see the different parts
Homogeneous Mixture So evenly mixed that you can’t see the different parts
Exothermic- heat energy EXITS the system - ex. Combustion, burning http://www.graspr.com/videos/potassium-permanganate-and-glycerine-2
Salt An example of an exothermic reaction is the mixture of sodium metal and chlorine gas which yields table salt. 2Na(s) + Cl2(g) 2NaCl(s) + energy http://www.schooltube.com/video/2fa9cb3e39064832b31d/Reaction-of-Sodium-and-Chlorine
Endothermic- heat energy ENTERS the system - surroundings usually feel cooler ex. Cold packs, melting ice
How do cold packs work? The outer pouch contains water. The inner pouch contains ammonium-nitrate. When you “pop” the inner pouch, the chemical reaction absorbs heat energy from the surroundings. This is an endothermic reaction. The temperature of the solution falls to about 35 F for 10 to 15 minutes.
