Answer to Problem 52A
Moles of H2O = 0.5 moles H2O
Moles of O2 = 0.25 moles O2
Explanation of Solution
The given reaction is as follows:
Given: 0.5 moles H2O2
Mole ratio H2O2 : H2O = 2:2 = 1:1
Thus,
Mole Ratio H2O2 ; O2 = 2:1
Thus,
(b)
Interpretation:
The number of moles of each product e produced by complete conversion of 0.50 moles of the reactant indicated bold in given reaction needs to be determined.
Concept Introduction:
If complete conversion of any reactant takes place in the chemical reaction, it is considered as a limiting reactant.
(b)

Answer to Problem 52A
Moles of KCl = 0.5 moles KCl
Moles of O2 = 0.75 moles O2
Explanation of Solution
The given reaction is as follows:
Moles of KClO3 = 0.5 moles
Mole Ratio KClO3 : KCl = 2:2 = 1:1
Thus,
Mole Ratio KClO3 : O2 = 2:3
Thus,
(c)
Interpretation:
The number of moles of each product produced by complete conversion of 0.50 moles of the reactant indicated in boldface needs to be determined.
Concept Introduction:
If complete conversion of any reactant takes place in the chemical reaction, it is considered as a limiting reactant.

Answer to Problem 52A
Moles of AlCl3 = 0.5 moles AlCl3
Moles of H2 = 0.75 moles H2
Explanation of Solution
The given reaction is as follows:
Moles of Al = 0.5 moles
Mole Ratio Al : AlCl3 = 2:2 = 1:1
Thus,
Mole Ratio Al : H2 = 2:3
Thus,
(d)
Interpretation:
The number of moles of each product produced by complete conversion of 0.50 moles of the reactant indicated in boldface needs to be determined.
Concept Introduction:

Answer to Problem 52A
moles CO2 = 1.5 moles CO2
moles H2O = 2.0 moles H2O
Explanation of Solution
Moles of C3H8 = 0.5 moles
Mole Ratio C3H8 : CO2 = 1:3
Thus,
Mole Ratio C3H8 : H2O = 1:4
Thus,
