The statement that correctly relates science and its influence on society is : Science can be used to address societal problems, but it is not always successful

for example, science can be used to address food shortage. Through various biotechnology, society doesn't have to be worry about food shortage in the future

hope this helps

What is the longest wavelength in the Balmer series? (Hint: the Rydberg constant for Hydrogen is 1.096776×107 1/m, and the Balme

boyakko [2]

Answer: The longest wavelength of light is 656.5 nm

Explanation:

For the longest wavelength, the transition should be from n to n+1, where: n = lower energy level

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

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

Where,

$\lambda$ = Wavelength of radiation

$R_H$ = Rydberg's Constant = $1.096776\times 10^7m^{-1}$

$n_f$ = Higher energy level = $n_i+1=(2+1)=3$

$n_i$ = Lower energy level = 2 (Balmer series)

Putting the values in above equation, we get:

$\frac{1}{\lambda }=1.096776\times 10^7m^{-1}\left(\frac{1}{2^2}-\frac{1}{3^2} \right )\\\\\lambda =\frac{1}{1.5233\times 10^6m^{-1}}=6.565\times 10^{-7}m$

Converting this into nanometers, we use the conversion factor:

$1m=10^9nm$

So, $6.565\times 10^{-7}m\times (\frac{10^9nm}{1m})=656.5nm$

Hence, the longest wavelength of light is 656.5 nm

Which of the subshells below do not exist due to the constraints upon the angular momentum quantum number?A) 2dB) 2sC) 2pD) all

Gnom [1K]

Answer:

Option A): Due to the constraints upton the angular momentum quantum number, the subshell 2d does not exist.

Explanation:

The angular momentum quantum number, identified with the letter l (lowercase L), number is the second quantum number.

This number identifies the shape of the orbital or kind of subshell.

The possible values of the angular momentum quantum number, l, are constrained by the value of the principal quantum number n: l can take values from 0 to n - 1.

So, you can use this guide:

Principal quantum Angular momentum Shape of the orbital

number, n quantum number, l

1 0 s

2 0, 1 s, p

3 0, 1, 2 s, p, d

Hence,

the subshell 2d (n = 2, l = 2) is not feasible.

2s (option B) is possible: n = 2, l = 0

2p (option C) is possible: n = 2, l = 1
