How many grams of aluminum is produced from the decomposition of 34grams of aluminum oxide
Answered by DrBob222
First you must understand that this is not a proper question because Al2O3 is not decomposed by heat. However, this is how you work this hypothetical question.
2Al2O3 ==> 4Al + 3O2

mols Al2O3 = grams/molar mass = ?
mols Al produced = 2*mols Al2O3
g Al = mols Al x atomic mass Al = ?
