Answer:
When the atoms are freezing, they lose energy.
I hope this helped at all.
Answer:
A
Explanation:
Acetals are geminal-diether derivatives of aldehydes or ketones, formed by reaction with two equivalents (or an excess amount) of an alcohol and elimination of water. Ketone derivatives of this kind were once called ketals, but modern usage has dropped that term.
To achieve effective hemiacetal or acetal formation, two additional features must be implemented. First, an acid catalyst must be used because alcohol is a weak nucleophile and second the water produced with the acetal must be removed from the reaction.
I would say that the density increases because the distance between the molecules decreases, and therefore becomes smaller, and vice versa the density increases, and that is a physical change not a chemical change.
Explanation:
According to the given data, the turnover number can be calculated as follows.
Turnover number = 
Therefore, moles of 
hydrolyzed is as follows.
Moles of hydrolyzed = 
= 
= 0.00682 moles
Now, moles of hydolyzed per second is calculated as follows.
Moles of hydolyzed per second = 
= 
And,
Moles of enzyme = 
= 
= 
moles
Therefore, the value of 
is as follows.
= 
per second
= 
per minute
= 
per minute
Thus, we can conclude that the turnover number () of carbonic anhydrase (in units of 
) is per minute.
Answer:
The answer is
<h2>[OH-] = 1.66 × 10^-14 M</h2>
Explanation:
To find the [OH-] we must first find the pH and the pOH of the solution
That's
pH + pOH = 14
pOH = 14 - pH
To find the pH we use the formula
pH = -log [H3O+]
From the question
[H3O+] = 0.6 M
pH = - log 0.6
pH = 0.22
pOH = 14 - 0.22
pOH = 13.78
We can now find the [OH -] in the solution using the formula
pOH = - log [OH-]
13.78 = - log [OH-]
Find the antilog of both sides
We have the final answer as
<h3>[OH-] = 1.66 × 10^-14 M</h3>
