Explain why, when the imidazole ring of histidine is protonated, the double-bonded nitrogen is the nitrogen that accepts the pro

ton. (hint: localized electrons are more apt to be protonated than delocalized electrons.)

The important thing to note is the reason why electron react is due to the instability of the electrons. All elements wants to aim the electron configuration of the noble gases. This is the most stable form in which each of the orbitals are sufficiently filled. When it comes to bonding, the order of reactivity is: alkynes > alkenes > alkanes. Alkynes are compounds with triple bonds, alkenes with double bonds and alkanes with single bonds. The single bonds are called saturated hydrocarbons. This is because they have reached stability, so it is quite difficult to react this with reducing or oxidizing agents. Alkynes and alkenes are unsaturated hydrocarbons. They readily react with reducing and oxidizing agents so as to become saturated, as well. The underlying principle for this is that single bonds contain sigma bonds which is the head-on overlapping of electrons. These is the strongest type of covalent bond. Double and triple bonds contain pi bonds which is the side overlapping of electrons orbitals. Hence, these electrons would be easily separated making it more reactive especially during protonation.

Answer:

\boxed{It\ will\ shift\ to\ create\ less\ of\ substance\ A}

Explanation:

If the concentration of any substance A in a dynamic equilibrium increases, The equilibrium will be  shifted to its opposite side so that Substance A can be created less and the substance opposite to A can be created more so that a "dynamic equilibrium" can again be established.

g Which ONE of the following pure substances will exhibit hydrogen bonding? A) methyl fluoride, FCH3 B) dimethyl ether, CH3C–O–C
luda_lava [24]

Answer:

C) formaldehyde, H2C=O.

Explanation:

Hello,

In this case, given that the hydrogen bondings are known as partial intermolecular interactions between a lone pair on an electron rich donor atom, particularly oxygen, and the antibonding molecular orbital of a bond between hydrogen and a more electronegative atom or group. Thus, among the options, C) formaldehyde, H2C=O, will exhibit hydrogen bonding since the lone pair of electrons of the oxygen at the carbonyl group, are able to interact with hydrogen (in the form of water).

Best regards.

Mr. Avogadro has 20 grams of radioactive Pa-234. How many atoms of Pa-234 does Mr. Avogadro have? PLEASE HELP WILL MARK BRAINLIE
jolli1 [7]

Answer:

The number of atoms in 20 grams of Pa-234 is 5.14 ×10²² atoms

Explanation:

Given that the molar mass of Pa-234 (protactinium) is 234.04331, we have

The number of moles of protactinium in 20 grams of Pa-234, we have

Number of moles = Mass/(Molar mass) = 20/234.04331 = 0.0855 moles

One mole of Pa-234 contains 6.02×10²³ atoms, therefore, we have;

0.0855 moles of Pa-234 contains 0.0855× 6.02×10²³  = 5.14 ×10²² atoms

Therefore, the number of atoms in 20 grams of Pa-234 = 5.14 ×10²² atoms.
