The given salinity is 24ppt
The relation between salinity and grams is
it means there is 24 parts of salt per 1000 parts of water
ppt: parts per thousand
Or
there is 24 grams of salt per 1000g of water
thus the value 24 ppt signifies that there is 24g of salt dissolved in 1000g or 1kg of water
Explanation:
Atomic number of hydrogen is 1 and its electronic configuration is . So, in order to attain stability it needs to gain one more electron from another atom.
As helium cannot donate its one valence electron because if it does so then there will be no electron present in a hydrogen atom which is not possible. Therefore, it needs to share its valence electron with another atom.
A chemical bond formed by sharing of electrons is known as a covalent bond. So, hydrogen atom always shares its valence electron and hence, it always forms a covalent bond.
On the other hand, atomic number of helium is 2 and its electronic configuration is .
Since, helium atom has completely fill orbital so, it is stable in nature. Therefore, it will neither gain or lose electrons under normal conditions.
As a result, helium will not form a covalent bond.
Answer:
See explanation
Explanation:
The synthesis of aspirin is shown in the reaction scheme attached to this answer. The production of aspirin involves the reaction of acetyl salicyclic acid and acetic anhydride. HA in the reaction mechanism refers to an acid that is used in the reaction
Similarly benzamide, is converted to the carbonyl carbocation by reaction with acid. The -NH2 group is protonated and subsequently departs as a leaving group. An OH^- completes the mechanism forming a carboxylic acid. The movement of electrons is shown in the image attached.
Again, the diazotization of benzamide using sodium nitrate and concentrated HCl yields benzene diazonium chloride. Addition of water to benzene diazonium chloride yields the benzoic acid and nitrogen gas.
This is an incomplete question, the image for the given question is attached below.
Answer : The wavelength of photon would be absorbed,
Explanation :
From the given diagram of energy we conclude that,
Energy at ground state, A = 400 zJ
Energy of 2nd excited state, C = 1050 zJ
Now we have to calculate the energy of the photon.
Now we have to calculate the wavelength of the photon.
Formula used :
As,
So,
where,
E = energy of photon =
= frequency of photon
h = Planck's constant =
= wavelength of photon = ?
c = speed of light =
Now put all the given values in the above formula, we get:
Therefore, the wavelength of photon would be absorbed,
