(b)
Answer to Problem M.8E
Amount of aluminum chloride produced is
Explanation of Solution
The balanced chemical equation is given as follows;
Mass of aluminum oxide taken is
Limiting reactant:
As there are three reactants in the chemical equation, the limiting reactant can be found out by calculating the number of moles of aluminum chloride produced for the individual reactants.
One mole of aluminum oxide produces two moles of aluminum chloride. Therefore,
Three moles of carbon produces two moles of aluminum chloride. Therefore,
Three moles of molecular chlorine produces two moles of aluminum chloride. Therefore,
The moles of
Thus the amount of aluminum chloride produced is
