There are eight diastereomers of 1,2,3,4,5,6-hexachlorocyclohexane. One of them is drawn. Draw the other seven in the cyclohexane framework below (5 points). One isomer loses HCl in an E2 reaction nearly 1000 times more slowly than the others. Circle the isomer that reacts so slowly, draw its corresponding chair conformers and explain the reason for the slow rate. (5 points).
Answers
Answer:
Attached below diagram of the eight diastereomers
The Isomer that reacts so slowly is DIASTEREOMER 8
Explanation:
The Isomer that reacts so slowly is DIASTEREOMER 8 in an E2 reaction and this is because no pair of chlorine and hydrogen atoms can assume the anti-periplanar orientation that is preferred in an E2 elimination

Answer and Explanation:
Solutions that have a pH of 8 would be considered a Weak Base.
This is because a weak base is a base that, upon dissolution in water, does not dissociate completely.
Solutions/liquids that have a pH higher than a pH of 7 are basic solutions, while solutions/liquids that have a pH lower than a pH of 7 are acidic solutions.
When the pH level is closer to 7, it is weak, and when it is far from 7, like if it is 1 or 12, then it is a strong acid/base.

1/5 divided by 3/4 fraction
Answers
Answer:
4/15
Explanation:
we can write out an equation by doing (1/5 ÷ 3/4) and then switch the sign to multiplication and we can keep the first fraction the same (in this case 1/5) and then we flip the second fraction BUT when we flip the second fraction upside-down we have to change the symbol to multiplication (1/5x4/3)
then after that all we do is multiply the denominators and numerators :)
1 x 4 = 4
_______
5 x 3 = 15
answer would be 4/15
Which of the following statements about electronegativity are true? (Select that all apply)
Answers
Answer: The question is incomplete and the options are not given but here are d options from another website.
a. Electronegativity increases as you move to the right of the periodic table.
B. Electronegativity is the ability of an atom to attract electrons.
c. A very electronegative atom easily gives up electrons.
d. Electronegativity increases with a decreased number of protons.
The correct options are
a. Electronegativity increases as you move to the right of the periodic table.
B. Electronegativity is the ability of an atom to attract electrons.
d. Electronegativity increases with a decreased number of protons.
Explanation:
This is because Electronegativity is the ability of an element to attract pair of electrons to itself.
Electronegativity increases as a result of increase in protons and when there is more electron pull.
As, the size of an element decreases, the valence electrons are attracted near to the nucleus. Therefore, there is increase in attraction between shared electron and nucleus.

25.0g of Aluminum metal is combined with
45.Og Copper(ll) Chloride to produce Aluminum Chloride
and Copper metal
1. Write and balance the chemical equation.
2. Write the needed mole ratio between reactants.
3. What is the mole ratio you have from the data?
4. What is in excess and what is limited? (Show Work)
5. What is the theoretical yield of Aluminum Chloride?
Answers
Answer: 1. [tex]2Al+3CuCl_2\rightarrow 2AlCl_3+3Cu[/tex]
2. 3 moles of [tex]CuCl_2[/tex] : 2 moles of [tex]Al[/tex]
3. 0.33 moles of [tex]CuCl_2[/tex] : 0.92 moles of [tex]Al[/tex]
4. [tex]CuCl_2[/tex] is the limiting reagent and [tex]Al[/tex] is the excess reagent.
5. Theoretical yield of [tex]AlCl_3[/tex] is 29.3 g
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of} Al=\frac{25.0g}{27g/mol}=0.92moles[/tex]
[tex]\text{Moles of} CuCl_2=\frac{45.0g}{134g/mol}=0.33moles[/tex]
The balanced chemical equation is:
[tex]2Al+3CuCl_2\rightarrow 2AlCl_3+3Cu[/tex]
According to stoichiometry :
3 moles of [tex]CuCl_2[/tex] require = 2 moles of [tex]Al[/tex]
Thus 0.33 moles of [tex]CuCl_2[/tex] will require=[tex]\frac{2}{3}\times 0.33=0.22moles[/tex] of [tex]Al[/tex]
Thus [tex]CuCl_2[/tex] is the limiting reagent as it limits the formation of product and [tex]Al[/tex] is the excess reagent.
As 3 moles of [tex]CuCl_2[/tex] give = 2 moles of [tex]AlCl_3[/tex]
Thus 0.33 moles of [tex]CuCl_2[/tex] give =[tex]\frac{2}{3}\times 0.33=0.22moles[/tex] of [tex]AlCl_3[/tex]
Theoretical yield of [tex]AlCl_3=moles\times {\text {Molar mass}}=0.22moles\times 133.34g/mol=29.3[/tex]
Thus 29.3 g of aluminium chloride is formed.
