7. which is the following is the highest?a. 12°Rb. 15°Cc. 68°Fd. 273 K
12 R = 15 C
68 F = 20 C
273 K = 0 C
68°F is the highest*12°R
12°R=4/5 ×C
C = 5/4 ×12=60/4=20 °C
*15°C
*68°f
68°f = 9/5 C (-32)
C= 5/9 ×68 (-32)
= 40 -32
= 8°C
*273°k = 0°C
So the highest number is 12°R
8. The boiling point of water is ... degree celcius *

9. why the boiling point in the mountain is 80 degrees
Translated:
mengapa titik didih di gunung adalah 80 derajat?
air yang di didihkan di daerah dataran tinggi/pegunungan cenderung lebih cepat mendidih ketimbang air yang dididihkan di dataran rendah karena adanya perbedaan tekanan udara luar di antara dua daerah/dataran tersebut.

12. the highest point of a submarine is 1 m above sea level. the lowest point is -5m below sea level. calculate the height of the submarine.
Jawaban:
the height of it is -2 m below sea level
13. A 2.00-g sample of a large biomolecule was dissolved in 15.0 g carbon tetrachloride. The boiling point of this solution was determined to be 77.85 oC. Calculate the molar mass of the biomolecule. For carbon tetrachloride, the boiling-point constant is 5.03oC .kg/mol, and the boiling point of pure carbon tetrachloride is 76.50oC
we will use boiling point formula:
ΔT = i Kb m
when ΔT is the temperature change from the pure solvent's boiling point to the boiling point of the solution = 77.85 °C - 76.5 °C = 1.35
and Kb is the boiling point constant =5.03
and m = molality
i = vant's Hoff factor
so by substitution, we can get the molality:
1.35 = 1 * 5.03 * m
∴ m = 0.27
when molality = moles / mass Kg
0.27 = moles / 0.015Kg
∴ moles = 0.00405 moles
∴ The molar mass = mass / moles
= 2 g / 0.00405 moles
= 493.8 g /mol
14. which of the following noun phrases is right? a. A glass of sweet black coffee b. A very new luxurious bus c. The white highest building d. The main road most crowded
Jawaban:
a. and b.
Penjelasan:
a. is a word that makes sense and contains no errors or wrong orders of word, this also applies at b.
c. has an error in it's order which is supposed to be "The Highest White Building" or some sort (don't really know how to explain) and the fact that d. is supposed to be "The main road is the most crowded" or "The Most crowded main road"
hope this helps cause I got kinda confused, am just a bocil.
15. CausemyA large number of soluter existing in a solutiona. the elevation of Saturated vapor pressureb. the elevation of Freezing point.c. the depressionpressured. the depression of boiling pointe. the depression of freezing pointOFOsmotic
Jawaban: E. The depression of freezing point
Penjelasan:
Sifat koligatif larutan ada 4, yakni:
1) Penurunan Tekanan Uap
2) Kenaikan Titik Didih
3) Penurunan Titik Beku
4) Tekanan osmotik
Pilihan a salah, karena kenaikan tekanan uap bukan sifat koligatif larutan. Seharusnya the DEPRESSION of saturated vapor pressure.
Pilihan b salah, karena kenaikan titik beku bukan sifat koligatif larutan. Seharusnya the DEPRESSION of freezing point
Pilihan c salah, karena penurunan tekanan osmotik juga bukan sifat koligatif larutan. Seharusnya kenaikan tekanan osmotik, yakni the ELEVATION of osmotic pressure
Pilihan d salah, karena penurunan titik didih bukan sifat koligatif larutan. Seharusnya the ELEVATION of boiling point.
Pilihan e tepat, karena sesuai dengan penurunan titik beku, yang merupakan salah satu dari 4 sifat koligatif larutan.

16. The normal boiling point of 2-Propanol, (CH3) 2CHOH, is 83OC, while acetone, (CH3) 2C = O, is 56OC. The reason is that the boiling point of 2-propanol is higher because ....
Jawaban:
boiling point of compound depends on its molecular forces. Stronger molecular forces, higher melting point it has. in 2-propanol, it contains -OH group that can form hydrogen bonding between other molecule while in acetone can't. Acetone just can form London forces or dipole-dipole forces, and we know that hydrogen bonding is stronger than London or dipole-dipole forces.

17. The normal boiling point of water is 100.0 °C, and the heat of vaporization is ΔHvap = 40.7 kJ/mol. What is the boiling point of water in °C on top of Pikes Peak in Colorado, where P = 407 mm Hg?
Tekanan Uap, Temperatur awal dan Temperatur Akhir dalam persoalan Kimia
Penjelasan:
Diketahui :
T1 = 100°C
dirubah menjadi satuan Kelvin = 373 K
ΔHvap = 40.7 KJ/mol
diubah menjadi satuan J/mol = 40700 J/mol
P = 407 mmHg
diubah menjadi satuan atm = 0,5355 atm
R = 8,314 J/mol.K
nilai ketetapan
Ditanya : T2....?
Penyelesaian :
[tex]ln (\frac{1}{P2}) = (\frac{Hvap}{R} ) (\frac{1}{T2} - \frac{1}{T1} )[/tex]
[tex]ln (\frac{1}{0,5355}) = (\frac{40700}{8,314} ) (\frac{1}{T2} - \frac{1}{373} )\\[/tex]
ln 1,8674 = 4895,35 [tex](\frac{1}{T2} - \frac{1}{373})[/tex]
0,62455 = [tex](\frac{4895,35}{T2} - \frac{4895,35}{373})[/tex]
0,62455 = [tex]\frac{4895,35}{T2}[/tex] - 13,124
[tex]\frac{4895,35}{T2}[/tex] = 0,62455 + 13,124
[tex]\frac{4895,35}{T2}[/tex] = 13,7488
T2 = [tex]\frac{4895,35}{13,7488}[/tex]
T2 = 356,056 K
Dari perhitungan diatas didapatkan nilai dari temperatur water atauT2 on top of pikes peak in Colorado sebesar 356,056 K atau sama dengan 83°C
