Answer:
The protonated form is predominant when aspirin is absorbed more readily. The ratio of conjugate base to acid is 1 to 100.
Explanation:
Aspirin is more readily absorbed when it is protonated, that is when pH is lower than pKa (<em>more H⁺ available in the medium</em>). We can confirm this using Henderson-Hasselbalch equation for pH = 1.5:
When aspirin is absorbed more readily the ratio of conjugate base to acid is 1 to 100, being the acid the <em>predominant</em> form.
Is not adequate to prevent dehydration effects in the cell
Answer:
True
Explanation:
Due to the fact that it is an equation that expresses the concentrations of reactants or products as a function of time, meaning that it describes the change in concentration of reactant(s) per change in time.
It's simple, just follow my steps.
1º - in 1 L we have
of
2º - let's find the number of moles.
3º - The concentration will be
But we have this reaction
This concentration will be the concentration of
considering
and
We can replace it
Therefore the
is:
The mass of 1.20x10^25 atoms of Ca is 8000 grams
