4-aminobenzoic acid
137.14 g/mol
Benzocaine
165.19 g/mol
A student starts with 0.345 g of pure 4-aminobenzoic acid, (molar mass 137.14 g/mol) and ends up with 0.345 g benzocaine
(molar mass 165.19 g/mol).
Given that ethanol is in excess, what are the theoretical and percent yields for this reaction? Assume all starting material is
converted to product when calculating the theoretical yield.

theoretical yield:
%
percent yield:

it's all four options.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
