To prevent tank rupture during deep-space travel, an engineering team is studying the effect of temperature on gases confined to

small volumes. What is the pressure of 2.60 mol of gas D measured at 251 ∘C in a 1.75-L container assuming ideal behavior? Express your answer with the appropriate units.

Answer: 63.88 atm

Explanation:

To answer this, we use the formula PV = nRT since the asumption is that the gas has an ideal behavior

where number of mole = 2.60 mol, R(gas constant) = 0.08205746 L atm/K mol,

T = 251 ∘C = (251 + 273) K = 524 K, Volume = 1.75 L

Making Pressure the subject of the formula, we have

P = nRT/V = 2.6 * 0.08205746 * 524/2.75 = 63.88 atm

Ksju [112]

Answer:

1.1 percent

Explanation:

C6H5COOH⇌C6H5COO+H

Ka = [C6H5COO-][H+]/[C6H5COOH]

From pKa of 4.2, Ka = 6.3x10^-5

6.3x10^-5 = (x)(x)/0.51-x and assuming x is small...

6.3x10^-5 = x^2/0.51

x^2 = 3.213x10^-5

x =5.67 x10^-3

(5.67x10^-3/0.51)x 100 =1.1 percent

The size of earthquakes is usually measured using the moment magnitude scale, which is a measure of the energy released.
meriva

Answer:True

Explanation: Moment magnitude is used by the USGS- it is based on the total moment release of the earthquake. Moment is a product of the distance and the force. The moment magnitude scale gives an esitmate of the total energy released from the earthquake

Veronika [31]

Answer: The average potential energy of the PIB is 0 irrespective of the wave function.

Explanation:

⟨H⟩=⟨KE⟩+⟨V⟩

the nn quantum number

⟨KE⟩=(π^2 ℏ^2)/(2mL^2 )

the average kinetic energy of the wavefunction is dependent on

⟨V⟩=∫sin(kx)0sin(kx)dx=0

The average potential energy of the PIB is 0 irrespective of the wave function.

⟨H⟩=⟨KE⟩=(π^2 ℏ^2)/(2mL^2 )
