Answer:

17.27 atm

Explanation:

Use the ideal gas law or PV = nRT

We are solving for pressure here so lets isolate for P before we plug in values:

P = \frac{nRT}{V}

So first to get n or the number of moles we need to convert the grams of N2O to moles of N2O. We can do this by multiplying by the inverse of the molar mass like so:

\frac{519.93g(N2O)}{1} \frac{mol}{44.013g(N2O)}

Our grams of N2O would cancel and give us 11.813 mol of N2O

Now all thats left is to plug in and solve with the correct value for R which in this case for all of our units to cancel is 0.08206

P = \frac{(11.813)(0.08206)(125.63)}{7.05}

P = 17.27 atm

(I would double check the calculator work if it is for correctness just be sure)

Answer:

The pressure of the gas is 17.27 atm

Explanation:

Step 1: Data given

Mass of N2O = 519.93 grams

Molar mass of N2O = 44.01 g/mol

Volume = 7.05 L

Temperature = 125.63 K

Step 2: Calculate moles N2O

Moles N2O = mass N2O / molar mass N2O

Moles N2O = 519.93 grams / 44.01 g/mol

Moles N2O = 11.81 moles

Step 3: Calculate pressure

p*V = n*R*T

p = (n*R*T)/V

⇒with p = the pressure of the gas = TO BE DETERMINED

⇒with n = the number of moles of gas = 11.81 moles

⇒with R = the gas constant = 0.08206 L*atm/mol*K

⇒with T = the temperature = 125.63 K

⇒with V  = the volume = 7.05 L

p = (11.81 * 0.08206 * 125.63) / 7.05

p = 17.27 atm

The pressure of the gas is 17.27 atm

Individual particles move with the wave.
MArishka [77]

Answer:

No.

Explanation:

No, individual particles do not move with the wave, it only oscillates back and forth its mean position. The particles in the medium transfer its energy to their neighboring particles and in that way the energy moves in the form of wave. The particles only vibrates on its means position instead of moving from one place to another. So we can conclude that Individual particles do not move with the wave.

fills a 500.mL flask with 3.6atm of carbon monoxide gas and 1.2atm of water vapor. When the mixture has come to equilibrium she
enot [183]

Answer:

The answer to the question is

The pressure of carbon dioxide after equilibrium is reached the second time is 0.27 atm rounded to 2 significant digits

Explanation:

To solve the question, we note that the mole ratio of the constituent is proportional to their partial pressure

At the first trial the mixture contains

3.6 atm CO

1.2 atm H₂O (g)

Total pressure = 3.6+1.2= 4.8 atm

which gives

3.36 atm CO

0.96 atm H₂O (g)

0.24 atm H₂ (g)

That is

CO+H₂O→CO(g)+H₂ (g)

therefore the mixture contained

0.24 atm CO₂ and the total pressure =

3.36+0.96+0.24+0.24 = 4.8 atm

when an extra 1.8 atm of CO is added we get Increase in the mole fraction of CO we have one mole of CO produces one mole of H₂

At equilibrium we have 0.24*0.24/(3.36*0.96) = 0.017857

adding 1.8 atm CO gives 4.46 atm hence we have

 (0.24+x)(0.24+x)/(4.46-x)(0.96-x) = 0.017857

which gives x = 0.031 atm or x = -0.6183 atm

Dealing with only the positive values we have the pressure of carbon dioxide = 0.24+0.03 = 0.27 atm
