Answer: The mass percentage of is 5.86%
Explanation:
To calculate the mass percentage of in the sample it is necessary to know the mass of the solute (
in this case), and the mass of the solution (pesticide sample, whose mass is explicit in the letter of the problem).
To calculate the mass of the solute, we must take the mass of the precipitate. We can establish a relation between the mass of
and
using the stoichiometry of the compounds:
Since for every mole of Tl in there are two moles of Tl in
, we have:
Using the molar mass of we have:
Finally, we can use the mass percentage formula:
Answer:
Protons 4 or 5 are most acidic.
Explanation:
As mentioned there are four types of hydrogen in Hexane-2,4-dione.
The numbering are shown in the figure for your better understanding.
As shown in the figure if we remove the proton from carbon number 3 (protons number 4 or 5), it will result in formation of a carbanion. This carbanion is stabilized due to presence of -I group oxygen and there is possibility of resonance (as shown).
Thus protons 4 or 5 are most acidic.
