A sample of diborane gas (B2H6), a substance that bursts into flame when exposed to air, has a pressure of 345 torr at a tempera

ture of -15ºC and a volume of 3.48 L. If conditions are changed so that the temperature is 36ºC and the pressure is 468 torr, what will be the volume of the sample?

Answer:

The final volume is 3.07L

Explanation:

The general gas law will be used:

P1V1 /T1 = P2V2 /T2

V2 =P1 V1 T2 / P2 T1

Give the variables to the standard unit:

P1 = 345 torr = 345 /760 atm = 0.4539atm

T1 = -15°C = -15 + 273 = 258K

V1 = 3.48L

T2 = 36°C = 36+ 273 = 309K

P2 = 468 torr = 468 * 1/ 760 atm = 0.6158atm

V2 = ?

Equate the values into the gas equation, you have:

V2 = 0.4539 * 3.48 * 309 / 0.6158 * 258

V2 = 488.0877 /158.8764

V2 = 3.07

The final volume is 3.07L

Write the full Nernst Equation (i.e. not just at 298K) and define each term:
alex41 [277]

Answer :

The Nernst equation :

E_{cell}=E^o_{cell}-\frac{2.303RT}{nF}\log \frac{[Anode]}{[Cathode]}

where,

E^0 = standard cell potential

n = number of electrons in oxidation-reduction reaction

F = Faraday constant = 96500 C

R= gas constant = 8.314 J/Kmol

T = temperature

[Anode] = anodic ion concentration

[Cathode] = cathodic ion concentration

Avagadros Law..<br>Definition please..​
Nikitich [7]

Answer:

"Avogadro's law is an experimental gas law relating the volume of a gas to the amount of substance of gas present. The law is a specific case of the ideal gas law. A modern statement is: Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules."

Rank the following compounds from highest boiling to lowest boiling. To rank items as equivalent, overlap them.
Olegator [25]

1-pentanol > 1-butanol > 1-chlorobutane > pentane

Explanation:

You my find in the attached picture the structures of the compounds, names and also the variation of their boiling points.

Alcohols have higher boiling points because they form hydrogen bonds between the molecules.
