Ответ:
0.1832 moles of ethyl acetate (
)
Explanation:
1. Find the balanced chemical equation:
In the production of ethyl acetate, the acetic acid
reacts with ethanol to produce ethyl acetate
and water, that is:
2. Find the theoretical maximum moles of ethyl acetate
:
As the problem says that the acetic acid
is the limiting reagent, use stoichiometry to find the moles of ethyl acetate produced:
Ответ:
B) You are to continue heating the round-bottom flask until all liquid has been distilled.
Explanation:
Fractional distillation refers to a method that's useful for the separation of mixtures of solvents whereby there is less than 40°C in the boiling point difference.
With regards to the options given, the incorrect statement about the procedure for distillation is that you are to continue heating the round-bottom flask until all liquid has been distilled. This isn't correct.
