Answer:p-hydroxybenzaldehyde is stronger acid to phenol
para-cyanophenol is stronger acid to meta-cyanophenol
o-fluorophenol is stronger acid to p-fluorophenol.
Explanation:
The PKa tool relative to Ph are used to contrast the pairs.
The pKa of phenol is 10. The pKa of p-hydroxybenzaldehyde is 9.24
The pKa for meta-cyanophenol is 8.61 and the pKa for para-cyanophenol is 7.95.
The pKa value of o-fluorophenol is 8.7, while that of the p-fluorophenol is 9.9. It's obvious that the inductive effect is more dominant at ortho-position, which results in a more acidic nature
The pKa is the pH value at which a chemical species will accept or donate a proton. The lower the pKa, the stronger the acid and the greater the ability to donate a proton in aqueous solution.
Answer:
<h3>The answer is 2.50 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 25 g
volume = 10 mL
We have
We have the final answer as
<h3>2.50 g/mL</h3>
Hope this helps you
Since we are basing the rate with respect to O3, therefore
the rate would simply be the concentration divided by the total reaction time.
That is:
rate of reaction = 0.05 M / 16 seconds
rate of reaction = 3.125 x 10^-3 M / second
or
<span>rate of reaction = 0.003125 M / second</span>
<span> the compound is butylcyclohexyl</span>
When atoms absorb energy electrons move into higher energy level.These electrons lose energy by emitting light when they return to lower energy levels.
