Calculate the wavelength, in nanometers, of the spectral line produced when an electron in a hydrogen atom undergoes the transit

Lapatulllka [165]

<u>Answer:</u> The wavelength of spectral line is 656 nm

<u>Explanation:</u>

To calculate the wavelength of light, we use Rydberg's Equation:

$\frac{1}{\lambda}=R_H\left(\frac{1}{n_f^2}-\frac{1}{n_i^2} \right )$

Where,

$\lambda$ = Wavelength of radiation

$R_H$ = Rydberg's Constant = $1.097\times 10^7m^{-1}$

$n_f$ = Final energy level = 2

$n_i$ = Initial energy level = 3

Putting the values in above equation, we get:

$\frac{1}{\lambda }=1.097\times 10^7m^{-1}\left(\frac{1}{2^2}-\frac{1}{3^2} \right )\\\\\lambda =\frac{1}{1.524\times 10^6m^{-1}}=6.56\times 10^{-7}m$

Converting this into nanometers, we use the conversion factor:

$1m=10^9nm$

So, $6.56\times 10^{-7}m\times (\frac{10^9nm}{1m})=656nm$

Hence, the wavelength of spectral line is 656 nm

How many grams of mgcl2 is produced if 4. 67 moles of hcl react

frosja888 [35]

The mass of MgCl₂ produced is 5.685 grams.

Mass is the quantity of matter of a physical body.

The reaction is

Mg + 2HCl → MgCl₂ + H₂

2 mole of HCl

(2 × 36.458) = 72.8 g

1 moles of MgCl₂

(1 × 95.21 g) = 95.21 g

1 g Mg will produce = $\dfrac{95. 21}{78.2}$

4.67 mol Mg will produce

$\dfrac{95. 21}{78.2} \times 4.67 = 5.685$

Thus, the mass of MgCl₂ produced is 5.685 grams.
