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) -> 2al2o3(s)
a mixture of 82.49 g of aluminum (m= 26.98 g/mol) and 117.65 g of oxygen (m =32.00 g/mol) is allowed to react. identify the limiting reactant and determine the mass of the excess reactant present in the vessel when the reaction is complete.
a) oxygen is the limiting reactant; 19.81 g of aluminum remain
b) oxygen is the limiting reactant; 35.16 g of aluminum remain
c) aluminum is the limiting reactant; 16.70 g of oxygen remain
d)aluminum is the limiting reactant; 35.16 g of oxygen remain
e)aluminum is the limiting reactant; 44.24 g of oxygen remain
