jeka943 years ago
3 0

Answer:

Explanation:

One CH4 molecules = 10 electrons ( Carbon 6e + 4Hydrogen 4e)

A mole of any substance witll have = 6.023*10^23 atom/ molecuels,

One mole of any substnce is equal is nothing but its moalr mass

Molar mass of CH4 = 16.04

It mean,

16.04  g of CH4 has = 6.023*10^23 molecules of methane

but

4.2 gram of CH4   = 6.023*10^23 * 4.2 /16.04 = 1.58*10^23 molecuels of CH4

So one molecule has =10 electrons

1.58*10^23 molecuels will have = 1.58*10^23  * 10 = 1.58*10^24

Hope this help you

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.
