The thermite process is used to mend railroad tracks together. It combines aluminum powder with ferric oxide. The reaction is: 2Al + Fe(III)2 O3 = 2Fe + Al2O3 If 1 kilogram of iron (III) oxide is used, what is the minimum amount of aluminum power to use to insure that all metallic iron that can be made is made?
a. 256 grams Al
b. 276 grams Al
c. 315 graMs L
d. 338 grams Al
e. 395 grams Al
