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

Yes because the equation is balanced!
Answer:
a. 52.8
Explanation:
To find the number of moles of HCl we use the relation M₁V₁=M₂V₂
where M₁ is the initial molarity, M₂ the new molarity, V₁ the initial volume used, and V₂ the final volume obtained.
M₁=7.91 M
M₂=2.13 M
V₁=?
V₂=196.1 mL
Replacing these values in the relationship.
M₁V₁=M₂V₂
7.91 M× V₁=2.13 M×196.1 mL
V₁=(2.13 M×196.1 mL)/7.91 M
=52.8 mL
