Place the following transitions of the hydrogen atom in order from longest to shortest wavelength of the photon emitted. Rank fr
gizmo_the_mogwai [7]

Answer:

7 to 4     (higher  \lambda)

5 to 3

3 to 2

4 to 2   (lower  \lambda)

Explanation:

We can use the Rydberg formula which relates the wavelength of the photon emissions to the principle quantum numbers involved in the transition:

\frac{1}{\lambda}=R((\frac{1}{n_1^2})-(\frac{1}{n_2^2}))

with n_1 final n, and n_2 initial n

evaluating for each transition:

7 to 4 \frac{1}{\lambda} = R((\frac{1}{4^2})-(\frac{1}{7^2}))= R(1/16-1/49)=R(0.042)

5 to 3 \frac{1}{\lambda}= R(1/9-1/25)=R(0.071)

4 to 2 \frac{1}{\lambda}= R(1/4-1/16)=R(0.1875)

3 to 2 \frac{1}{\lambda}= R(1/4-1/9)=R(0.139)

Note that the above formula is written for \frac{1}{\lambda}, so lower \frac{1}{\lambda} value obtained involves higher \lambda.

So we should order from lower to higher \frac{1}{\lambda}

7 to 4     (higher  \lambda)

5 to 3

3 to 2

4 to 2   (lower  \lambda)

Note: Take into account that longer wavelength involves lower energy (E=\frac{hc}{\lambda}).

A 2.10 L vessel contains 4.65 mol of nitrous oxide (N2O) at 3.82 atm. What will be the pressure of this gas in a container that’
sveticcg [70]

Answer:

The answer to your question is 7.64 atm

Explanation:

Data

Volume 1 = V1 = 2.1 l

moles = 4.65

Pressure 1 = P1 = 3.82 atm

Volume 2 = Volume 1/2

Pressure 2 = ?

Process

1.- Calculate the new volume

Volume 2 = 2.10/2

Volume 2 = 1.05 l

2.- Use Boyle's law to find the Pressure

             P1V1 = P2V2

-Solve for P2

              P2 = P1V1 / V2

-Substitution

              P2 = (3.82)(2.1) / 1.05

-Simplification

              P2 = 8.022/1.05

-Result

              P2 = 7.64 atm
