Answer: The correct answer is option B)
in the synthesis of cryolite for aluminum production.
Explanation:
Hydrogen fluoride (HF) is used in synthesis of cryolite for aluminum production.
HF is a gas that dissolves in water to form hydrofluoric acid. However, HF also react with halogenated alkanes like trichloromethane CHCl3 to form organofluorine compounds that serves as precursors in the synthesis of cryolite, an Ore from which aluminum is produced

The Correct choices are :
- 1. The elements have filled valence levels.
- 2. potassium (K) with a 1+ charge
Answer:
7 protons
Isotopes are atoms that have the same number of protons but different numbers of neutrons in the nucleus. You know that nitrogen-14 has 7 protons in the nucleus because it is an isotope of nitrogen, which has an atomic number equal to 7 .
Answer:
See figure 1
Explanation:
In this question, we have to find first the <u>chiral carbons</u> on 1,2-difluoro-1,2-dimethylcyclopentane. Carbons 1 and 2. Then, using the <u>Cahn–Ingold–Prelog priority rules</u>. We can draw all the stereoisomers. If we have 2 chiral carbons we will have (
) <u>4 isomers</u>. With this in mind we can have the R,R isomer; the S,S isomer; the S,R isomer, and the R,S isomer. We have to remember that:
<u>Priority 1 = "F"</u>
<u>Priority 2= "C"</u>
<u>Priority 3= "CH2"</u>
<u>Priority 4 = "CH3"</u>
I hope it helps!
Answer:
5000 and
indicate that there is more B than A at equilibrium
Explanation:
For the given reaction: ![K=\frac{[B]}{[A]}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BB%5D%7D%7B%5BA%5D%7D)
where [B] and [A] represents equilibrium concentration B and A respectively. K represents equilibrium constant
More B than A at equilibrium means, [B] > [A]
So, ![K=\frac{[B]}{[A]}>1](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BB%5D%7D%7B%5BA%5D%7D%3E1)
As, both 5000 and
are greater than 1 therefore these two K values indicate that there is more B than A at equilibrium
