Answer: <span>Arachidonic Acid and PGE</span>₁<span> are both carboxylic acids with
<u>Twenty Carbon</u> atoms. The differences are that Arachidonic acid contains
<u>Four <em>cis</em> Double Bonds</u> and no other functional groups, whereas PGE</span>₁<span> has
<u>One <em>Trans</em> Double Bond, Two Hydroxyl and One Ketone Functional Groups.</u>. In addition, a part of the PGE</span>₁<span> chain forms a
<u>Five Membered Ring</u>.
Structures of Both Arachidonic Acid and PGE</span>₁ are shown Below,
There are no above options to choose from so I am giving an example of a X3Y2 formula which is Magnesium nitride, the formula is Mg3N2.
By decreasing n we can increase presure because decrease in n will shift equilibrium to either forward or reverse direction
Explanation:
Moles of NaOH = 10g / (40g/mol) = 0.25mol.
0.25mol / 500g = 0.50mol / 1000g = 0.50mol/dm³.
The molarity is 0.50mol/dm³.
