This separation technique is similar to sublimation. The impure solid is dissolved in a solvent. The solution is heated and evaporation takes place. The hot solution is allowed to cool and crystals will gradually form.
Crystallization
This separation technique is applicable for separating a liquid mixture. As you heat the liquid, it evaporates and the solid crystals will start to form as sublimate.
Sublimation
This technique separates an undissolved solid from a liquid using filter paper.
Filtration
This separation technique involves separating the components of a mixture by passing the mixture through a stationary phase.
Chromatography
This separation technique separates a mixture by allowing the liquid to evaporate and the solid particles will remain in the evaporating dish.
Evaporation
This separation technique separates an undissolved solid from a liquid.
Decantation
This separation technique purifies a liquid mixture by using the boiling points of its substances.
Distillation
Type of mixture that can be physically separated.
Heterogeneous mixture
Type of mixture that has no visible boundaries of separation.
Homogeneous mixture
Consists of two or more combined elements.
Compound
Consists of only one kind of atom.
Elements
Mixtures can be broken down into _____ and _____.
Homogeneous and Heterogeneous
Pure substances can be broken down into _____ and _____.
Elements and Compounds
Matter can be classified into two categories: _____ and _____
Pure Substance and Mixture
Properties that do not depend on the amount of matter being measured.
Intensive properties
Properties that depend on the amount of matter being measured.
Extensive properties
Properties that can be observed or measured by changing the chemical nature of the substance.
Chemical properties
Properties that can be observed or measured without changing the composition of the substance.
Physical properties
The molecules are far apart from each other.
Gas
The molecules are close together but not held in fixed positions. They are arranged in a disorderly manner and can move freely.
Liquid
The molecules are held together by very strong forces of attraction.
Solid
The three (3) states of matter.
Solid, Liquid, and Gas
