Mixture
Heterogeneous & homogeneous
Homogeneous
Homo = same
Uniform composition and appearance throughout
Example: Apple Juice, Air
Heterogeneous
Hetero = different
Consists of visibly different substances or phases (gas,liquid,solid)
Example: Cereal in milk, soil
Suspension
Heterogeneous mixture with a solid and a liquid phase
Emulsion
Heterogeneous mixture with two liquids, which can't dissolve in each other
exothermic
the reaction releases energy
Example: combustion (lighting a candle)
endothermic
reaction absorbs energy from surroundings
Example: melting an ice cube
activation energy
the requirement of the smallest amount of energy to start a reaction OR energy amount available in a system to start a reaction
