Answer:
Chlorine ion will attack the carbocation and double bond will not be created
Explanation:
The use of concentrated hydrochloric acid wiill be a poor choice as the acid catalyst for the formation of cyclohexane by dehydration of cyclohexanol because of the following reasons:
1) There will be presence of chlorine ions and they will attack the carbocation to form a single bond.
2) The formation of double bond will not occur in the process.
Therefore, it is a poor choice to use concentrated hydrochloric acid as the acid catalyst for the formation of cyclohexane by dehydration of cyclohexanol.
Answer: The concentration of hydrogen ion is 2.5 x 10∧-3.
Explanation:
It is well known that; pH + pOH = 14
∴ pH + 11.40 = 14
pH = 14 -11.40 = 2.60
Remember that,
pH = - Log [ H+ ]
2.60 = - log [H+]
To get the hydrogen ion concentration, we take the anti-log of 2.60.
[H+] = Antilog 2.60 = 2.5 x 10∧-3.
Answer: C) Heat
What I know so far is that heat makes it harder for the electrons to reach the source, thus making it hard to collide with the nucleus, but I’m not sure so you can see if it’s correct.
Question 22: conclusion
Question 23: analyze
Answer: Water
Explanation:
Chemically speaking, a solution has two components: solute and solvent.
The <u>solute</u> is that substance (usually solid, but it can also be liquid or gas) that dissolves in a liquid substance and <u>its proportion in the resulting solution is usually less than the solvent.
</u>
The <u>solvent</u> is the substance used to <u>dissolve the solute, and generally its proportion in the resulting solution is greater.</u> Being the most common used solvent water.
This means that in a solution there is usually more solvent than solute.
So, in the case of the hydrogen peroxide solution, since the proportion is 
to 
, the hydrogen peroxide is the solute and water is the solvent.
