Bauxite consists mainly of AlOs, which react with carbon at high temperatures.
The process uses large amounts of electric power; that's why it makes sense to recycle aluminum cans. The balanced equation for the reaction is
A1203 (s) + 3 C (s) ---> 2 AI (1) + 3 CO (g)

Suppose you react 25.0 grams of AlO, with 15.0 grams of carbon.
a. Determine which reagent is limiting and which is excess.
b. What theoretical yield (grams) of aluminum metal can be formed?
c. What mass of the excess reactant will be left over?
pls help me!!!
