32
Density
mass/volume
33
Matter definition
anything occupying space and has mass.
34
solid properties
fixed volume and fixed shape
35
liquid properties
has an exact volume and has no specific shape
36
gas properties
no fixed volume or shape
37
homogenous
has indistinguishable visible traits.
38
heterogenous
has distinguishable visible traits.
39
solutions
a homogenous mixture
40
pure substance
matter with constant composition of the same thing.
41
physical change
the chemical composition of the matter doesn't change just the structure.
42
distillation
boiling a liquid to separate the solid components from the liquid ones
43
chromatography
application of a series of methods that uses a system with 2 states the mobile and stationary phase. Works because the components of the mixture have different affinities.
44
calculate the Rf factor of the yellow part of a mixture that move 3 centimeters, and the water moved 5 centimeters
0.60
45
compound
combination of elements that has constant composition and can be broken down into elements through chemical processes.
46
chemical change
where a substance becomes a different substance with different properties and composition.
47
elements
substances that cannot be broken down into simpler substances through chemical or physical means.
48
precision
how close your results are together the higher the precision.
49
accuracy
The closer you are to the correct answer the higher the accuracy
50
Miles to feet
1 mile=5280
51
Miles to yards
1 mile=1760 yards
52
How do you find the relative uncertainty of a measurement
Uncertainty/measurement
53
How is relative uncertainty useful
You can add 2 relative uncertainties to get the relative uncertainty of the sum of the 2 uncertain numbers
54
milliliters to cubic centimeters
1 milliliter = 1 cubic centimeter
55
What is the Rf factor
Known as the retention factor is a numerical value that shows its attraction to the 2 different phases the stationary and mobile phase.
