101
science concerned with the study of matter and the transformation it undergoes
chemistry
102
property that can be observed without changing the composition of the substance involved
physical property
103
cannot be seen through
opaque
104
can be pounded into a thin sheet
malleable
105
can be drawn into a wire
ductile
106
has own form and will not take the shape of a container
definite shape
107
doesn't have its own form and will take the shape of a container
indefinite shape
108
cannot be compressed
definite volume
109
can be compressed
indefinite volume
110
why is gas compressible
extra space, easier to compress, doesn't have own shape
111
the process by when the component of a mixture can be separated by using differences in physical properties
purification
112
pure substance composted of only one type of atom
element
113
pure substance composed of two or more different atoms that have chemically combined
compound
114
are the properties of a compound the same as the properties of the elements that it is composed of?
no
115
for defined quantities, how many sig figs do they have
infinite
116
keep track of where the uncertainty is in our calculations
sig figs
117
how close a measurement is to the actual true value
accuracy
118
how close several measurements are to one another
precision
119
all matter is made of atoms
all atoms of a given element are identical both in mass and properties
compounds are formed by the combination of two or more different kinds of atoms
chemical reactions involve the combination, separation, or rearrangement of atoms
daltons atomic theory (1803)
120
matter is neither created nor destroyed during a chemical reaction
law of conservation of matter
121
ratio of masses of the elements in pure samples of a given compound do not vary with the origin of the sample
law of constant composition
122
elements may combine in more than one set of proportions with each set representing a different compound
law of multiple proportions
