Gay-Lusaac's Law The graduate student then heats the
container to a temperature of 750 C
3. What is the new temperature of
the system?
A graduate student measures
the pressure of a particular
gos in a closed, foed volume
container to be 100 atm oto
temperature of 20 0 C
1 What is the temperature of
the system?
20°C+223-243K
2 What is the system's pressure?
Tarm
4 What is the new pressure inside
the container?
=0
The graduate student chills the same container in
ice, bringing the temperature of the gas to O C.
The graduate student chills the same container now
with liquid nitrogen/ The liquid nitrogen causes the
temperature of the gas to drop to -200.00
5. What is the new temperature of the
gas?
7. What is the new temperature of the
gas?
6. What is the new pressure inside the container?
8. What is the new pressure inside the container?

Nonmetal halogen family atmoic mass 35

What are transitions between a liquid and a solid called? identify which way they are transitioning

Straightforward questions answered in the powerpoint slidesreaction: heating the starting materials under refluxwhat does it mean to heat under reflux? why do we choose water as the reflux solvent? what are boiling chips used for? why do we put a condenser on top of the reaction? why do we add heat and let the reaction stir for 30 minutes? why do we add sulfuric acid to the reaction after it cools as opposed to when it’s still hot? separation: filtration of precipitatewhy don’t we do an aqueous and organic extraction in the separatory funnel? why do you rinse the salicylic acid on the filter with ice cold water? purification: recrystallization of salicylic acid (no hot filtration needed)what is the difference in the amount of room temperature water vs. boiling water needed to dissolve the salicylic acid (assume a 1.2 gram yield of salicylic acid)? remember, in the lab if you need x ml of boiling water to dissolve a solid, then you should add a little more (definitely no more than 1.5 times the theoretical amount) to ensure it doesn’t recrystallize prematurely.analysis: melting point of salicylic acidwhat can you conclude if the melting point of the salicylic acid you just synthesized is 152-155oc and the 1: 1 mix of your product and “synthetic” salicylic acid is 151-154oc?
