Both pyrrole and pyridine are aromatic compounds, and undergo electrophilic aromatic substitution (EAS). Using a resonance argum

ent, predict the regiochemistry of EAS on both pyrrole and pyridine. As part of your argument, you must draw resonance structures for the arenium ion leading to each possible regiochemistry, and compare the stabilities of the resonance hybrids. In addition, make a reasoned statement about whether you think each one would react faster or slower than benzene and why.

What is the difference between pH and pOH?
natali 33 [55]

Answer:

pH measures ratio of H+ ions to OH- ions of substances

pOH measures ratio of OH- ions to H+ ions of substances

Explanation:

pH is a scale which measures the ratio of H+ ions to OH- ions to identify how acidic or basic a substance is. This is because acidic substances have high amounts of H+ ions and low amounts of OH- ions, and therefore have a higher ratio of H+ to OH- ions. (And vice versa for bases, low H+ to OH- ratio) On a pH scale, acidic substances have a pH of 0 to 7, water (neutral pH, not acidic nor basic) has a pH of 7, and bases have a pH of 7-14.

pOH is very similar to pH but measures the opposite: the ratio of OH- ions (indicative of a base) to H+ ions (indicative of an acid). Therefore the pH values are reversed on the scale: Basic substances have pOHs below 7, and acidic substances are above 7 on the pOH scale.

Fundamentally, these two scales measure the same thing is the same way, one just measures the ratio one way (H+:OH-), while the other measured them the other way (OH-:H+), resulting in flipped values on the scales:

pH: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14

      <---Acidic--->   <------Basic------->

pOH: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14

         <----Basic---->  <-----Acidic------->

Hope this helped!

How heavy is one atom of hydrogen
Harman [31]

Hello!

the atomic mass of one atom of hydrogen is equal to 1.00784 in atomic mass units

one atomic mass unit is equal to 3.6609e-27 pounds

which means one atom of hydrogen is equal to 3.9478732e-27 pounds

I hope this helps, and have a nice day!
