Problem 51E

Urea ( CH4N2O ) is a common fertilizer that is synthesized by the reaction of ammonia ( NH3 ) with carbon dioxide:

In an industrial synthesis of urea, a chemist combines 136.4 kg of ammonia with 211.4 kg of carbon dioxide and obtains 168.4 kg of urea. Determine the limiting reactant, theoretical yield of urea, and percent yield for the reaction.

Step-by-Step Solution:
Step 1 of 3

Solution: Here, we are going to identify the elements which are oxidized and reduced in the given set of equation. Step1: Oxidation refers to loss of electrons by an atom, molecule or ion whereas reduction means gain of electrons by an atom, molecule or ion. Oxidation leads to increase in oxidation state whereas reduction leads to decrease in oxidation state of the atom, molecule or ion. The reactant which loses electron is said to be oxidized and the reactant which gains electron is said to be reduced. Step2: a) The given reaction is: N + 32 -----2 2NH 3 Here, the oxidation and reduction takes place in the following manner: As we have seen, the oxidation number of nitrogen changes from 0 to -3(gain of electrons) i.e., its oxidation number decreases. Also, the oxidation number of hydrogen increases from 0 to +1(loss of electrons). Hence, nitrogen is reduced and hydrogen is oxidized. b) The given reaction is 3Fe(NO ) + 2Al ---------> 3Fe + 2Al(NO ) 3 2 3 3 Here, the oxidation and reduction takes place in the following manner: As we have...
