The limiting reagent will be Al
<h3>What are limiting reagents?</h3>
They are reagents that limit the quantity of products that are formed in reactions. 
From the equation of the reaction:

The mole ratio of Al to O2 is 4:3.
With 2 moles of Al and 2 moles of O2, Al becomes limiting while O2 is in excess. 
With 2 moles of O2, the amount of Al required should be:
                           2 x 4/3 = 2.67 moles.
With 2 moles of Al, the amount of O2 required should be:
                     2 x 3/4 = 1.5 moles
Thus, O2 is in excess by 0.5 moles.

An excited electron is in a <em>high-energy state</em>.
When it drops to the lower-level ground state, it must get rid of this excess energy by <em>emitting it</em> as a quantum of light.
 
        
             
        
        
        
 If the reaction is a chemical change, new substances with different properties and identities are formed. This may be indicated by the production of an odor, a change in color or energy, or the formation of a solid.
