Answer:

n_1=1.459

Explanation:

Hello,

In this case, the Rydberd formula is:

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

Whereas \lambda is wavelength of photon,  R the Rydberg's constant,  Z the atomic number of the atom, in this case 1 as it is hydrogen,  n_1 is the initial level and n_2 is the final energy level .

In such a way, solving for n_1 one obtains:

\frac{1}{n_1^2}-\frac{1}{n_2^2} =\frac{1}{\lambda RZ^2}\\\frac{1}{n_1^2}=\frac{1}{\lambda RZ^2}+\frac{1}{n_2^2}\\\frac{1}{n_1^2}=\frac{1}{4.141x10^{-7}m*1.097x10^7m^{-1}*1^2}+\frac{1}{2^2} \\\frac{1}{n_1^2}=0.47\\n_1=\sqrt{\frac{1}{0.47}} \\n_1=1.459

Best regards.

Answer:

1

Explanation:

Using the Rydberg formula as:

\frac {1}{\lambda}=R_H\times Z^2\times (\frac {1}{n_{1}^2}-\frac {1}{n_{2}^2})

where,

λ is wavelength of photon

R = Rydberg's constant (1.097 × 10⁷ m⁻¹)

Z = atomic number of atom

n₁ is the initial final level and n₂ is the final energy level

For Hydrogen atom, Z= 1

n₂ = 2

Wavelength = 410.1 nm

Also,

1 nm = 10⁻⁹ m

So,

Wavelength = 410.1 × 10⁻⁹ m

Applying in the formula as:

\frac {1}{410.1\times 10^{-9}}=1.097\times 10^7\times 1^2\times (\frac {1}{n_{1}^2}-\frac {1}{2^2})

Solving for n₁ , we get

n₁ ≅ 1

Which term describes the molecule shown below h-c-c-h ethyne c2h2?
Andru [333]
Ethyne also known as Acetylene and is the simplest Alkyne belonging to  Unsaturated Hydrocarbons. It contains triple bond between two carbon atoms in a molecule. Carbon atoms in Acetylene are sp Hybridized and has a linear shape with bond angle of 180° is present between C-C-H bonds. This compound is also called as Binary Compound because it is made up of two elements i.e. Carbon and Hydrogen. The terminal Hydrogen in Acetylene is slightly Acidic in nature, and this compound can donate terminal proton to any strong base. These compounds generally give Electrophillic Addition Reactions.
