<h3>Procedural steps are: - </h3>
- On a small scale, the reaction is carried out by combining the alcohol, the haloalkane, and the phase transfer catalyst in a conical vial.
- To start the reaction, sodium hydoxide (base) is added.
- To prevent solvent evaporation, the reaction flask is covered and stirred during the reaction.
- TLC monitors the reaction's progress to ensure that no time is wasted.
- To remove any remaining water, the reaction solution is dried over calcium chloride.
- 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.

Answer:
D) dependent on the element that reacted with carbon.
Explanation:
Nuclear fusion involves the combination of small atomic nuclei to form larger ones. This combination or fusing of nuclei is always accompanied by the release of large amount of energy.
The fusion product depends on the combining elements that fuses together. As we would have it, the fusion results in the formation of a heavier nuclei. Therefore, the combination of the Carbon and the other element would yield another nuclei that is heavier.
First step: calculate the number of moles of sodium reacted
moles=mass/molar mass
31.5g/23g/mol =1.37moles
from the reaction above the reacting ratio of Na to H2 is 2:1 therefore moles of H2 is 1.37/2=0.685
At STP 1 mole = 22.4L what about 0.685 moles
22.4 x0.685=15.344L
Answer is: 2,42·10²² atoms of gold.
<span>1 ounce (oz) is equal to 28,34952 grams (g).
</span>0,375 oz = 10,631 g.
75% gold = 10,631 g · 0,75 = 7,973 g.
n(Au) = m(Au) ÷ M(Au).
n(Au) = 7,973 g ÷ 197 g/mol.
n(Au) = 0,0404 mol.
N(Au) = n(Au) · Na.
N(Au) = 0,0404 mol · 6,023·10²³ 1/mol.
N(Au) = 2,42·10²².
n - amount of substance.
Na - Avogadro number.
