Answer:
Exothermic reaction
Explanation:
Notice that the energy component is located on the right side of the reaction. The right side is always known as the product side. Whenever energy is located there, the reaction is known to give off energy - essentially, we can say that energy is a product, as well. Reactions that give off energy are known as exothermic reactions.
On the other hand, if the energy component was located on the left side, or reactant side, of the equation, it would be known as an endothermic reaction.
Here, it's exothermic.
Hope this helps!
Answer:
I, III, and V
Explanation:
All five options are correct.
However, your instructor is probably expecting the answer I, III, and V.
These three elements are on the left-hand side of the Periodic Table. Thus, they tend to lose electrons and form positive ions most easily.
H is the most reluctant to form a cation. Its first ionization energy is 1100 kJ·mol⁻¹.
However, F and He can lose electrons to form cations.
It takes only 1700 kJ·mol⁻¹ to remove an electron from F. However, F tends to add electrons to get a complete valence shell.
Even He, with a complete valence shell, will give up a valence electron for the expenditure of only 2400 kJ·mol⁻¹.

Explanation:
We know that some substituted benzene reacts faster than benzene towards electrophillic substitution. This is often due to the activation of the benzene ring towards electrophillic substitution by resonance.
-OCH3 directs an incoming electrophile (such as during bromination) to the ortho or para position. This is made possible by resonance (mesomeric) effect as shown in the image attached to this answer.
