Answer:
Condenser
Explanation:
A condenser is laboratory apparatus used to condense vapors — that is, turn them into liquids — by cooling them down. Condensers are routinely used in laboratory operations such as distillation, reflux, and extraction(Wikipedia).
Condensers of of practical importance especially in synthetic organic chemistry and in separation science where vapours are often condensed and collected the substance is collected in pure form by distillation.
6.73 L
This one requires the combined gas law.
P1V1/T1 = P2V2/T2
P1 = 150 kPa = 1.48 atm
V1 = 5 L
T1 = 300 K
P2 = 1 atm
V2 = This is what we’re solving for.
T2 = 273 K
P2 and T2 are based on the conditions of STP. I also changed P1 to atm to keep the units consistent.
Solve the equation for V2:
V2 = P1V1T2 / T1P2
V2 = (1.48 atm)(5 L)(273 K) / (300 K)(1 atm) = 6.73 L
Fill in the blank
The (blank) of a rock is a result of its mineral composition.
Answer:
Color
They are different because of the number of electrons and protons and heir composition
