The wavelength of the photon is  1026  Å

Rydberg unit of energy corresponds to the energy of the photon whose wave number is Rydberg constant.

The value for the rydberg constant is 10 973 731.6 m-1

The formula for the rydberg constant for hydrogen is

1 / λ = Rh (1 / n1^2 - 1 / n2^2)

where Rh is the Rydberg constant

For the transition of an electron in a hydrogen atom from n = 1 to n = 3

1 / λ = Rh (1 / 1^2 - 1 / 3^2)

1 / λ = Rh (0.888)

λ = 1.126 / Rh

λ = 1.126 /  10 973 731.6

   = 1.026 * 10^-7

   = 1026  Å

Hence, the wavelength of the photon is  1026  Å

How many grams of N2 gas are present in 1.13 L of gas at 2.09 atm and 291 K?
solong [7]

Answer:

Mass= 2.77g

Explanation:

Applying

P=2.09atm, V= 1.13L, R= 0.082, T= 291K, Mm of N2= 28

PV=nRT

NB

Moles(n) = m/M

PV=m/M×RT

m= PVM/RT

Substitute and Simplify

m= (2.09×1.13×28)/(0.082×291)

m= 2.77g

Select all statements that are correct:____
topjm [15]

Answer:

A, C and D are correct.

Explanation:

Hello.

In this case, since the relationship between the vapor pressure of a solution is directly proportional to the mole fraction of the solvent and the vapor pressure of the pure solvent as stated by the Raoult's law:

P_{vap}^{solution}=x_{solvent}P_{solvent}

Since the solute is not volatile, the mole fraction of the solute is not taken into account for vapor pressure of the solution, therefore A is correct whereas B is incorrect.

Moreover, since the higher the vapor pressure, the weaker the intermolecular forces due to the fact that less more molecules are like to change from liquid to vapor and therefore more energy is required for such change, we can evidence that both C and D are correct.

Best regards.

Design a synthesis of acetophenone from benzene or toluene. 1275q Part 1 out of 5 Choose the best option for the nucleophile pre
Trava [24]

Answer:

A Fridiel craft catalyst will convert benzene to acetophenone.

Permanganate catalyst can be used to convert toluene to acetophenone.

Explanation:

Benzene can be reduced to acetophenone by the addition of anhydrous aluminium chloride, AlCl₃

The mechanism is as follows:

Benzene + Acetyl choloride → acetophenone

To convert toluene to acetophenone, the following steps are necessary:

  • Oxidation of Toluene to Benzoic acid.

     This is done by refluxing toluene with alkaline potassium permanganate         (KMnO₄+ Na₂CO₃).

  • Benzoic acid is converted to Benzoyl chloride by treating with thioyl chloride and heating at about 80 ⁰C.
  • Benzoyl chloride is treated with methyl lithium to form Acetophenone.
