The value is
Explanation:
From the question we are told that
The equilibrium spacing is ![r = 0.074 nm= 0.074 *10^{-9} \ m](https://tex.z-dn.net/?f=r%20%3D%200.074%20nm%3D%200.074%20%2A10%5E%7B-9%7D%20%5C%20%20m)
The mass of a hydrogen atom is ![m = 1.67 *10^{-27} \ kg](https://tex.z-dn.net/?f=m%20%3D%20%201.67%20%2A10%5E%7B-27%7D%20%5C%20%20kg)
The principal quantum number of the second energy level is ![l = 3](https://tex.z-dn.net/?f=l%20%3D%20%203)
The principal quantum number of the first energy level is ![l = 2](https://tex.z-dn.net/?f=l%20%3D%20%202)
Given that the hydrogen molecule is a symmetrical diatomic molecule, its moment of inertia is mathematically represented as
![I = \frac{m}{2} r^2](https://tex.z-dn.net/?f=I%20%3D%20%20%5Cfrac%7Bm%7D%7B2%7D%20%20r%5E2)
Generally for rotational spectrum the energy level is mathematically represented as
![E = l(l + 1) * \frac{h^2}{8 \pi ^2 I}](https://tex.z-dn.net/?f=E%20%20%3D%20l%28l%20%2B%201%29%20%2A%20%5Cfrac%7Bh%5E2%7D%7B8%20%5Cpi%20%5E2%20I%7D)
Generally the energy difference between the first energy level and the second energy level is mathematically represented as
![\Delta E = [ l_2(l_2 + I) * \frac{h^2}{8 \pi ^2 I}]- [ l_1(l_1 + I) * \frac{h^2}{8 \pi ^2 I}]](https://tex.z-dn.net/?f=%5CDelta%20E%20%20%3D%20%5B%20l_2%28l_2%20%2B%20I%29%20%2A%20%5Cfrac%7Bh%5E2%7D%7B8%20%5Cpi%20%5E2%20I%7D%5D-%20%5B%20l_1%28l_1%20%2B%20I%29%20%2A%20%5Cfrac%7Bh%5E2%7D%7B8%20%5Cpi%20%5E2%20I%7D%5D)
=> ![\Delta E = [ 3(3 + 1) * \frac{h^2}{8 \pi ^2 I}]- [ 2(2 + 1) * \frac{h^2}{8 \pi ^2 I}]](https://tex.z-dn.net/?f=%5CDelta%20E%20%20%3D%20%5B%203%283%20%2B%201%29%20%2A%20%5Cfrac%7Bh%5E2%7D%7B8%20%5Cpi%20%5E2%20I%7D%5D-%20%5B%202%282%20%2B%201%29%20%2A%20%5Cfrac%7Bh%5E2%7D%7B8%20%5Cpi%20%5E2%20I%7D%5D)
=> ![\Delta E = \frac{6h^2}{8 \pi ^2 I}](https://tex.z-dn.net/?f=%5CDelta%20E%20%20%3D%20%20%5Cfrac%7B6h%5E2%7D%7B8%20%5Cpi%20%5E2%20I%7D)
substituting for I
![\Delta E = \frac{6h^2}{8 \pi ^2 [\frac{m}{2} * r^2]}](https://tex.z-dn.net/?f=%5CDelta%20E%20%20%3D%20%20%5Cfrac%7B6h%5E2%7D%7B8%20%5Cpi%20%5E2%20%5B%5Cfrac%7Bm%7D%7B2%7D%20%2A%20r%5E2%5D%7D)
=> ![\Delta E = \frac{3h^2}{2 \pi ^2 m * r^2}](https://tex.z-dn.net/?f=%5CDelta%20E%20%20%3D%20%20%5Cfrac%7B3h%5E2%7D%7B2%20%5Cpi%20%5E2%20m%20%2A%20r%5E2%7D)
Generally this difference in energy level can also be mathematically represented as
![\Delta E = \frac{hc}{\lambda}](https://tex.z-dn.net/?f=%5CDelta%20E%20%3D%20%5Cfrac%7Bhc%7D%7B%5Clambda%7D)

Here h is Planck's constant with value ![h = 6.62607015 * 10^{-34} J \cdot s](https://tex.z-dn.net/?f=h%20%3D%206.62607015%20%2A%2010%5E%7B-34%7D%20J%20%5Ccdot%20s)
and c is the speed of light with value ![c = 3.0*10^{8} \ m/s](https://tex.z-dn.net/?f=c%20%3D%20%203.0%2A10%5E%7B8%7D%20%5C%20%20m%2Fs)

B Phytoplankton - Zooplankton - Arctic cod - Ringed sal
Explanation:
The food chain that describes the path through which energy takes will be phytoplankton-zooplankton-Arctic cod-Ringed sal. Energy moves in the ecosystem from producers to primary consumers then secondary and tertiary consumers.
- Autotrophs are those organisms that manufacture their own food. The use chemical substances from the environment to produce their nourishment which serves as the source of energy for the whole ecosystem too.
- Autotrophs are the producers in any ecosystem and they are usually the plants.
- The phytoplankton is an autotroph.
- Next up are the primary consumers that takes up the produced food by the autotrophs for their own nourishment. In the chain above, the Zooplankton is the primary consumer.
- The secondary consumer that feeds on the zooplankton is the Arctic cod.
- The tertiary consumer is the Ringed Sal which feeds directly on the Arctic cod.

Answer:
In a chemical reaction, only the atoms present in the reactants can end up in the products. No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
