Nature of Matter
This state of matter is defined as having no definite shape or volume and is easily compressed
It also has the most kinetic energy
gas
This method of separating mixtures involves placing a drop of the mixture to be separated on a piece of absorbent paper and placing one edge of the paper in a suitable chemical solvent
It is also based on the different way that each component in a mixture interacts with a stationary liquid or solid phase
chromatography
The central portion of an atom that contains the most of the mass
nucleus
The sum of the number of protons and neutrons in an atom
mass number
Flammability is an example of this type of change
chemical change (property)
This state of matter is defined by having a definite volume and the shape of its container
liquid
This method of separating mixtures involves dissolving a solid mixture in a small volume of hot solvent and slowly cooling it
fractional crystallization
He proposed the planetary model of the atom
Ernest Rutherford
The value that equals an element's average atomic mass but lacks units
atomic weight
This subatomic particle is not found in the nucleus
electron
A substance consisting of two or more pure substances physically mixed but not chemically combined
mixture
This technique separates substances with similar boiling points by boiling the mixture beneath a tall column containing many surfaces on which vapor may condense
fractional distillation
This experiment led to the development of the planetary model
gold-foil experiment
This instrument is used to measure atomic mass
mass spectrometer
The law stating that the masses of each element in a given compound always have the same ratio
Law of Multiple Proportions
As the temperature of a sample of matter increases, this type of energy will also increase
kinetic energy
DAILY DOUBLE
Name the four observations that would suggest a chemical change has occurred.
This subatomic particle was used to measure the charge of Millikan's oil-drop experiment
electron
Name the classification of CO2 and C6H12O6
CO2 = element and molecule
C6H12O6 = compound and molecule
A mixture of pure substances that are incompletely mixed and form distinct phases
heterogeneous mixture
DAILY DOUBLE
Name the ideas associated with Dalton's atomic theory
Density is an example of this type of property
physical
This subatomic particle does not have a charge
neutron
The weighted average of the atomic masses of the naturally occurring isotopes of an element
average atomic mass
This theory states that a chemical reaction is the result of rearrangement, combination, or separation of atoms
Dalton's atomic theory
