How many grams are there in 7.3 moles of NH3?

12. If the total pressure exerted by 3 gases is 45 atm and each individual gas has the

Bumek [7]

Answer:

Partial pressure for each of the three gases, in the mixture is 15 atm

Explanation:

Remember that the total pressure of a mixture, is the sum of partial pressures from the gases contained in the mixture.

Our total pressure = 45 atm

The 3 gases have the same pressure, so we can propose this equation:

3x = 45 atm

where x is the partial pressure for each of the three gases.

x = 45/3 → 15 atm

2.) At what temperature in Celsius will a 1.0g sample of neon gas exert a pressure of 500 torr in a 5.01 L container. (Hint: use

Studentka2010 [4]

The required temperature of the sample of gas is 823K.

<h3>What is ideal gas equation?</h3>

Ideal gas equation gives idea about the behavior of gas at different condition & represented as:

PV = nRT, where

P = pressure = 500 torr = 0.657 atm
V = volume = 5.01 L
R = universal gas constant = 0.082 L.atm / K.mol
T = temperature = ?
n = moles

Moles will be calculated as:
n = W/M, where

W = given mass
M = molar mass

Moles of Neon gas = 1g / 20.1g/mol = 0.049 mole

On putting all these values in the above equation, we get

T = (0.657)(5.01) / (0.049)(0.082) = 822.8 = 823 K

Hence required temperature of the sample is 823 K.

g .For each of the following disubstituted cyclohexanes, indicate whether the substituents in the two chair conformations would

Kryger [21]

Answer:

a) Both chairs conformers have one of its substituents in an axial position and the other in an equatorial position

b) One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position

c) One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position

d) Both chairs have one of its substituents in an axial position and the other in an equatorial position

e) Both chairs have one of its substituents in an axial position and the other in an equatorial position

(f) One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position

Explanation:

Determine what the substituents would be

a) Cis-1,2- : Both chairs conformers have one of its substituents in an axial position and the other in an equatorial position

b) Trans-1,2- : One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position

c) Cis-1,3- : One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position

d) Trans-1,3- : Both chairs have one of its substituents in an axial position and the other in an equatorial position

e) Cis-1,4- : Both chairs have one of its substituents in an axial position and the other in an equatorial position

(f) Trans-1,4- : One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position

Why are people not able to scuba dive in the deep part of the ocean

Setler [38]

It's very dangerous to go that deep into the ocean due to the water pressure and the coldness, no human can physically comprehend it, so if you do end up diving that deep into the ocean, you will suffocate, crush to death, or freeze very quickly.
