Answer:
True
Explanation:
The arrangement of three groups COOH, CO, OH in the order of reducing boiling point is as follow -
COOH > OH > CO
COOH gets strongly polarised due to the presence of electron withdrawing carboxy group and hence have strong H+ bonds as compared to that of alcohol.
Hence the given statement is true.
To have the all three scales set at zero.
Answer:
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)

Answer:
Even small amounts of radiation over a prolonged period of time can be dangerous.
Explanation:
We all get exposed to radiation, such as through x-rays, and it's fine as one off experiences. However, if you're constantly dealing with radiation without any sort of protection, no matter how small the amount is, it could potentially lead to consequences like cancer. This is due to the fact that radiation can alter our genes
