13. What is a mixture? A mixture can be easily separated.
The components each keep their own properties.
The proportion of components is variable.
Not chemically combined

14. Types of Mixtures: Solution Colloid Suspension Homogeneous
Particles are distributed evenly
Ex: Kool-aid, Tea, Air,
Salt Water
Particles are dispersed throughout but are not heavy enough to settle out
Ex: Jell-O, Whipped cream, Milk, Mayonnaise, Silly Putty
Particles are dispersed throughout but settle out
Ex: Blood, Medicine, Snow globe
