What is Magnetic Separation
anything that takes up space or has mass is
what is matter
A substance made of only one type of particle
What is pure substance
in a salt water solutions this specific substance acts as the solute.
what is salt
a naturally occurring element found underground
what is uranium
which way of separation can you use to separate water and salt
what is evaporation
true or false
A mixture can be separated into its original parts by physical means like filtering.
what is true
a pure substance consisting of only one type of atom, which cannot be broken down into simpler substances by ordinary chemicals.
what is an element
often called the universal solvent it is the most common liquid used to dissolve substances in nature
what is water
true or false
uranium never stops being radioactive.
what is false?
name 3 types of ways to separate mixtures and Solutions.
ex.distillation
what is filtration, evaporation and magnetism
what is condensation
what is the process where gas turns into a liquid
a type of mixture with its components evenly distributed at the molecular level
what is a homogeneous mixture
this term describes the component of a solution that is present in the greatest amount and does the dissolving.
what is a solvent
can you find uranium in water?
what is yes
this technique separates mixtures like ink or dyes into individual colors
What is Chromatography
the direct transition of a substance from a solid to a gas without becoming a liquid first.
what is sublimation
this technique separates a mixture's components based on their different boiling points.
what is distillation
the solubility of these substances actually decreases as the temperature of the liquid solvent increases
what are gases
named after the seventh planet from the sun known as uranus this heavy metal is most famous for its use as fuel in nuclear power plants.
what is uranium
This method involves heating a liquid to form vapor, then cooling it back to liquid to separate components based on boiling points
What is Distillation
What are the five main points of particle theory
1.All matter is made of tiny particles.
2.There are empty spaces between particles.
3.Particles are always moving.
4.Particles move faster when heated.
5.Particles are attracted to each other.
this type of pure substance is made of two or more different elements that are chemically combined in a fixed ratio.
what is a compound
A solution is called this when it contains the maximum amount of solute that can be dissolved at a given temperature
what is a saturated solution
