centi is 1/100 of the base unit (tip for remembering: cent = 100)

micro is 1/1,000,000 of the base unit

nano is 1/1,000,000,000 of the base unit (tip for remembering: nano will have nine zeroes)

milli is 1/1,000 of the base unit

What do the electrons do in a Valteic cell

alexandr402 [8]

Answer:

In redox reactions, electrons are transferred from one species to another. If the reaction is spontaneous, energy is released, which can then be used to do useful work. To harness this energy, the reaction must be split into two separate half reactions: the oxidation and reduction reactions.

During bromination using NBS, the addition product is not observed because the rate of addition is _______than the rate of the c

Alecsey [184]

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.
