Aluminum reacts with oxygen to produce aluminum oxide which can
be used as an adsorbent, desiccant or catalyst for organic
reactions.
4Al(s)
+ 3O2(g) à 2Al2O3(s)
A mixture of 82.49g of aluminum and 117.65g of oxygen are
allowed to react. Identify the limiting reactant and
determine the mass of the excess reactant present in the vessel
when the reaction is complete.
Aluminum is the limiting reactant; 44.27g of O2 remain
Aluminum is the limiting reactant; 16.70g of O2 remain
Oxygen is the limiting reactant; 19.81g of Al remain
Oxygen is the limiting reactant; 35.16g of Al remain
