List the procedural steps, from start to finish, that are required to convert 2‑naphthol and allyl bromide into allyl 2‑naphthyl
elena-14-01-66 [18.8K]
<h3>Procedural steps are: - </h3>
  1. On a small scale, the reaction is carried out by combining the alcohol, the haloalkane, and the phase transfer catalyst in a conical vial.
  2. To start the reaction, sodium hydoxide (base) is added.
  3. To prevent solvent evaporation, the reaction flask is covered and stirred during the reaction.
  4. TLC monitors the reaction's progress to ensure that no time is wasted.
  5. To remove any remaining water, the reaction solution is dried over calcium chloride.
  6. Column chromatography is used to purify the product, and evaporation is used to collect it.
<h3>What is Catalysis?</h3>

Catalysis is the process of boosting the pace of a chemical reaction by using a catalyst. Catalysts are not consumed in the reaction and so survive it.

Which best describes a compound such as sodium chloride? a) a pure substance that can be separated into different elements by ph
vitfil [10]

Answer:

d) a pure substance that can be separated into different elements by chemical means.

Explanation:

Hello,

Sodium chloride (NaCl) is a chemical compound composed by sodium and chlorine. They are chemically bonded through a ionic bond which means that the sodium transfers just one electron (valence electron) to the chlorine to form the bond. Now, if we want to separate them, we must induce a chemical process because bond breaking implies a chemical change, not physical. Thus, a typical way to separate them (break the bond) is via electrolysis in which an electric driving force induce the aforementioned breakdown.

Best regards.

navik [9.2K]

Answer:

0.05

Explanation:

We find the rate of the chess

Sarah is 2.5/10

Arun is 1.6/8

We will get

0.25 for Sarah

0.20 for Arun

We subtract the two

0.25 - 0.20, we then get 0.05

Sarah has 0.05 more cheese in one serving than Arun
