The number 1 piece of PPE worn in the lab
Goggles
The three pieces of glassware that do basically the same thing
Beaker, Erlenmeyer flask, test tube
The curve of the liquid in a graduated cylinder.
Meniscus
Zeros at the beginning of a number are called this name, and are considered to be not significant.
Leading zeros
Observations that describe texture, color, odor, etc.
Qualitative Observations
The colors and categories of the NFPA label
blue - health, red - fire, yellow - reactivity, white - PPE
Bunsen Burner
This piece of glassware has one specific measurement, but is not used for measuring.
Volumetric Flask
Exact numbers have this many significant figures.
Infinite
Hypothesis
The 3 ways a chemical can get into your body
absorption, ingestion, inhilation
If you are making a chemical solution, this piece of glassware is best to use.
Volumetric flask
When reading a measurement from a graduated cylinder, this is the right way to do it.
At eye level and from the bottom of the meniscus
How many sigfigs are in the number below?
120 cm
2 sigfigs:
the 1 and 2 are significant
the 0 is not significant because there is no decimal
Which variable belongs on the x axis, and which belongs on the y axis?
x = ind, y = dep
The seven PPE hazards marked on an NFPA label
Corrosive, alkaline, acid, oxidizing, radioactive, reacts with water, and reacts with water and air.
Erlenmeyer created his flask to be a multipurpose tool. The flask is different from the beaker in this way.
Erlenmeyers are good for storing with rubber stoppers, and stirring.
The measurement of the following image would be:
89 mL
How many sigfigs are in the number below?
0.02030500 kL
There are 7 sigfigs
This statement summarizes the data found during an experiment
Inference
MSDS is an acronym that stands for:
Material Safety Data Sheet
These two lab tools are homonyms but have different uses.
Pipette and Pipet
The correct order from smallest to largest of the 7 metric conversions in grams
mg, cg, dc, g, Dg, Hg, Kg
How many sigfigs are in the number below?
1,530,700 bolts
Infinite
Control is a comparison and constant is an experimental parameter kept the same for the whole experiment
