Methods of Separation Flashcards
is a technique used in separating the solid components of a heterogeneous mixture
Handpicking
is define as to pass through a sorting device like a screen to sort, separate the large
Sieving/sifting
used to separate heavier and lighter substances, separate mixture by falling
Winnowing
used to separate solid from fluids by filter device
Filtration
solid particles trapped by filter paper
Residue
Liquid that pass has pass through the filter paper
Filtrate
semi-permeable paper that separates solids and liquids
Filter paper
used to separate magnetic substances
Magnetic separation
separating mixture by wax of evaporation
Evaporation to dryness
used to separate a solvent from a mixture by distilled
Distillation
separating liquid from solid
Decantation
saturated solution is obtained
Crystallization
It is the arrangement of the chemical elements
Periodic table
The periodic table lists the elements in order of?
increasing atomic number
Made up of only one kind of atom
Elements
There are currently ______elements
118 elements

Helium
Shorthand way of representing the elements
Chemical symbol
-shiny
-good conductor
-ductile
Metals
-dull(no shine)
-poor conductor
Non-metals
-characteristics of metals and non-metals
-semiconductor
Metalloids
They are placed to the lower right of the chemical symbols
Chemical formulas
Are small numbers used in chemical formulas
Subscripts
It is a special type of mixture(homogeneous mixture) that combines a solute and solvent
Solution
Solid part that gets dissolved
Solute
Liquid part that does the dissolving
Solvent
We can measure how easily a solute
will dissolve in a certain solvent. This measurement is called?
Solubility
Dissolve easily or quickly
High solubility
Does not dissolve easily
Low solubility
Small amount of solute and light solution appears
Dilute
Large amount of solute and dark solution appears
Concentrated
