Bismuth oxide reacts with carbon to form bismuth metal.?

Question

Bi2O3(s) + 3 C(s) 2 Bi(s) + 3 CO(g)

(a) When 320. g Bi2O3 reacts with excess carbon, how many moles of Bi2O3 react?
mol
(b) How many moles of Bi form?
mol

Answer 1

Come on" too easy. Just think it a while, and consider that in a) all Bi2O3 reacts, so just divide the mass by the molecular weight of Bi2O3. In b) just consider that you have two moles of Bi per each mole of Bi2O3, so multiply the result fo a) by 2. they teach these things at the kindergarden, you know? only kids use apples, sticks, balls, crayons or things alike.
