Which best represents a reaction mechanism?
2 answers:
Answer : The correct option is, (C)
Explanation :
Chemical equation : It is written in such a way that the symbolic representation of the reaction represents the reaction taking place in the system.
The reactants are written on the left-hand side and the products are written on the right-hand side of the equation and the reactant and products are separated by an arrow. The two or more reactants and products are separated by “+”.
Hence, the representation of chemical reaction will be,

Answer:
Up to
.
Explanation:
The equation for this reaction: is indeed balanced.
Notice that the coefficient of is
while that of
is
.
Therefore, each unit of this reaction would consume units of
while producing
units of
. In other words, this reaction would produce three times as much
as it consumes
.
If all that of
molecules are actually consumed through this reaction, three times as many
molecules would be produced. That corresponds to
of
molecules.
Answer:
d. Adding 5% HCl solution to the crude reaction mixture will protonate aniline increasing its solubility in the aqueous solution.
Explanation:
On this case, we have to check the <u>structures of each compound</u> (figure 1). For naphthalene we dont have <u>any functional groups</u> therefore, the addition of HCl or NaOH it will not affect naphthalene so <u>we can discard "B" and"C".</u>
When we add HCl solution we will have the production the presence of this <u>hydronium ion will protonate the acid</u>, so we can <u>discard a.</u>
<u />
Finally, for d when we add the <u>hydronium ion will react with aniline</u> (a base) and will produce an <u>ammonium ion</u>. This ammonium ion have a <u>positive charge</u>, therefore the <u>polarity will increase</u> and the molecule would be more soluble on water (figure 2).
I hope it helps!
