The Chemistry Department enforces a _____ _______ policy regarding lab safety violations. -
CorrECt ansWEr-zero tolerance
How should you be dressed in lab? - CorrECt ansWEr-1. Approved eye protection must be worn in
lab at all times
2. Full length pants and closed toe shoes
3. Cover midsection
What is the policy on food and drink in the lab? - CorrECt ansWEr-None is allowed. This includes
gum.
Who must be present for students to enter the lab? - CorrECt ansWEr-The TA
What kind of experiments can be performed? - CorrECt ansWEr-Only authorized experiments
under the supervision of the TA
What should you do if in the case of injury? - CorrECt ansWEr-Even if it is minor, treat it with first
aid and have another student notify the TA immediately of the injury.
How hot can a hot plate get and what should it be set at? - CorrECt ansWEr-They can exceed 550
C and should never be set past 3.
Where do you dispose of chemical waste? - CorrECt ansWEr-In appropriately marked waste
bottles.
, What do you do if you spill something? - CorrECt ansWEr-Make sure to clean it up immediately.
Use sodium bicarbonate for acid spills and boric acid with water for base spills.
What is the purpose of LabPro/LoggerPro? - CorrECt ansWEr-The program makes lab
measurements simpler and more accurate by using a computer to aid in data collection.
Freezing point is the same as ________ _______. - CorrECt ansWEr-Melting point
At what temperature does lauric acid freeze? - CorrECt ansWEr-43.5 C
How did we find the freezing point? - CorrECt ansWEr-We used a temperature probe to detect
the change in temperature as the lauric acid went from a liquid to a solid.
Where on the graph can you find the freezing point? - CorrECt ansWEr-It is the flat portion of the
graph.
Why is the freezing point flat on the graph? - CorrECt ansWEr-Because energy is being used to
rearrange the molecules instead of changing temperature.
When does supercooling happen? - CorrECt ansWEr-Right before the freezing point.
What is supercooling? - CorrECt ansWEr-It is when a substance drops suddenly to below its
freezing point before going up to the freezing point.
What is density? - CorrECt ansWEr-The ratio of its mass to its volume. D=m(g)/v(mL)
Is density an intensive or extensive property? - CorrECt ansWEr-Intensive
At what temperature is water most dense? - CorrECt ansWEr-4 C
