SolventPart of the solution that is present in largest amount

and dissolves a solute

What liquid is called the “universal solvent”? WATER

Solvent - Solute - Solution

Solute

Part of solution present in lesser amount and dissolved by solvent

SolutionA well mixed mixture containing a solvent and at

least one solute that has the same properties throughout.

Tasty solution activity

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

Heat- transfer of energy

Exothermic- heat energy EXITS the system- ex. Combustion, burning

SaltAn example of an exothermic reaction is the mixture of sodium metal and chlorine gas which yields table salt.

2Na(s) + Cl2(g) 2NaCl(s) + energyhttp://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
