4300 meters = approximately 14107.61 feet.
Boiling point is 212 degrees Fahrenheit at sea level.
(Each 500 feet increase in elevation will be lowered by approximately 1 degrees Fahrenheit)
14107.61 feet divided by 500 feet = <span>28.21522
So the boiling point would be lowered by about 28 degrees Fahrenheit at 4300 meters above sea level. Which will make your new boiling point 184 degrees Fahrenheit instead of 212.
184 degrees Fahrenheit = 84.4 degrees Celcius</span>
potassium reacts the most vigorously.
Answer:
The solution is not ideal.
The relative strengths of the solute-solvent interactions are greater compared to the solute-solute and solvent-solvent interactions
Explanation:
The total vapor pressure is the sum of the partial pressures of water and methanol, and they are calculated by the Raoult´s law equation:
Pₐ = Xₐ Pºₐ, where Pₐ is the partial pressure of component A
Xₐ is the molar fraction of A
P⁰ₐ is the pressure of pure A
So lets calculate the partial pressures of methanol and water and compare them with the given total vapor pressure of solution:
X H2O = 0.312 ⇒ X CH3OH = 1 - 0.312 = 0.688
PH2O = 0.312 x 55.3 torr = 17.3 torr
PCH3OH = 0.688 x 256 torr = 176.1 torr
Ptotal = PH2O + PCH3OH = 17.3 torr + 176.1 torr = 193.4 torr
This pressure is less than the experimental value of 211 torr. So the solution is not ideal. The relative strength of the solute-solvent interactions are greater than the solute-solute and solvent-solvent interactions.
The reason for this is the presence of hydrogen bonding between methanol and water.
60 i believe i haven't did science in a while sorry if im wrong though... ._.
