This is the answer of your question. ☺
Answer:
slower
Explanation:
NBS is used in place of Br2 during bromination because the use of Br2 tends to result in the formation of a large concentration of the addition product. This is because, the Br2 interacts with the double bond to yield only the dibromide (addition product).
The usefulness of NBS lies in the fact that it provides a lower concentration of Br2, and such that the rate addition is slower than the chain propagation steps. Only the monobromination product is observed
The low concentration of Br2 allows the free-radical reaction to out-compete the alkene addition reaction.
Answer:
Low-energy reactants become high-energy products.
Explanation:
In electrolysis, you are forcing a reaction to occur that otherwise wouldn't happen.
You are pumping energy into the system and converting low-energy reactants into high-energy products.
B is wrong. Nature tends to run downhill energetically, so high-energy reactants tend to form low-energy products spontaneously.
C and D are wrong. If an element is unreactive, it stays unreactive, and vice versa. You can't change the nature of an element.
Number of neutrons = mass number - atomic number
= 15 - 9
= 6
Answer:
40 mL
Explanation:
Volume=400g/10(g/mL)
= 40mL
