The first step of electrophilic aromatic substitution involves the formation of the arenium ion intermediate.

Chemistry
1 answer:
Anastaziya [24]3 years ago
4 0

Answer:

True

Explanation:

Aromatic compounds undergo substitution rather than addition reactions because the aromatic structure is maintained.

Electrophilic aromatic substitution begins with attack of the electrophile on the aromatic ring to yield a delocalized intermediate called the arenium intermediate. Loss of hydrogen from this intermediate yields the final product.

How many grams of water will be produced from 50 g hydrogen reacting with 50 g oxygen?
DanielleElmas [232]

We need to first come up with a balanced equation:


4H+O_{2} → 2H_{2}O


We know that the molar ratio of hydrogen to oxygen to water now is 4:1:2.


Converting the amount of grams given to moles is as follows:


Hydrogen: \frac{1mole}{1.008g}*50g=49.6mol


Oxygen: \frac{1mole}{15.999g}*50g=3.125mol


We know now that the limiting reactant is oxygen. We can then know that the number of moles of water are produced are double the number of moles of oxygen used due to the ratio that we established at the beginning - 4:1:2.


So we now can use 6.25 moles of water as the amount produced.


Then we convert moles of water to grams:


\frac{18.015g}{1mole} *6.25mol=112.59g


Now we know that there are 112.59g of water produced when we start with 50g of hydrogen and 50g of water.

Salt domes result when: 1. inland seas dry 2.the pressure of overlying rock forces the salt to rise 3. a layer of sedimentary sa
Ilia_Sergeevich [38]

Answer:

Salt domes result when <u><em>the pressure of overlying rock forces the salt to rise. (Option 2)</em></u>

Explanation:

In geology it is called the gently wavy and rounded relief dome.

Salt has some special properties like rock:

  • Salt has a lower specific gravity in relation to a common mineral.
  • Salts deform plastically and are very mobile.
  • Salts have a high water solubility.

These properties allow, if the pressure is very high, that the salt layers move upwards (due to their lower density). That is, the internal forces produce the elevation of the strata by means of the pressure they exert towards a higher point, generating that the salt looks for its way towards the surface [that is, the salt ascends through the sedimentary layers of the earth's crust, crossing them and deforming them] and causing the bulging structure. The oldest strata are located in the central area of the dome, while the most modern are distributed in the farthest radius. The structure is called salt or diapiro dome, the phenomenon by which it is formed is called diapirism.

Finally, you can say that <u><em>Salt domes result when the pressure of overlying rock forces the salt to rise.</em></u>
