Answer: The given statement is true.

Explanation:

A chemical change is a change that causes change in chemical composition of a substance.

This change is due to the exchange of electrons that lead to the formation or breaking of bonds.

For example, sodium atom on donating an electron to chlorine atom forms an ionic bond due to transfer of electron.

This formation of ionic bond leads to the formation of a new compound named as sodium chloride.

Therefore, we can conclude that the statement a chemical change involves the formation or the breaking of bonds, is true.

Draw every stereoisomer for 1,2-difluoro-1,2-dimethylcyclopentane. Use wedge-and-dash bonds for the substituent groups, and be s
Blizzard [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 (2^n=2^2=4) <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!

What is the hydroxide ion concentration in an aqueous solution with a hydrogen ion concentration of
Schach [20]
[H+][OH-] = 1x10-14 = Kw (Memorize this relationship)
(2.70x10-2)[OH-] = 1x10-14
[OH-] = 1x10-14/2.70x10-2
[OH-] = 3.70x10-13 M (assuming you ignore the autoionization of H2O)
