\[ {F}e_2O_3+2Al\implies Al_2O_3+2Fe\]

2Al is the limiting reagent right

did you check to see?

novice in chem,well i just looked at the atom it has 2 moles and Fe2O3 has 1 so yeah

to figure out which is limiting you want to to take Grams of reactant >mols of reactant>moles of product with both... which ever can make the least amount of moles of product is your limiting reactant

Fe2O3 M=55 m=250 n=4.5 Al M=26 m=150 n=5.7

alright and then there is 2 aluminum molecules per 2 iron

so you cna make 9.16 moles of iron with 9.16 moles of aluminum

wait 9.6 was error i took wrong mass Al n=5.7

Outkast3r09Best ResponseYou've already chosen the best response.1
o wait nvm 5.7 molecules of aluminum can make 5.7 molecules for iron

Outkast3r09Best ResponseYou've already chosen the best response.1
however per each iron oxide molecule you can make 2 iron oxide molecules

Outkast3r09Best ResponseYou've already chosen the best response.1
so multiply 4.5*2 =9 moles of iron.... since you can only make 5.7 moles with the aluminum , Al is your limiting reagent

Outkast3r09Best ResponseYou've already chosen the best response.1
now just change 5.7 moles of Fe to grams

Outkast3r09Best ResponseYou've already chosen the best response.1
so that would be your answer

JonaskBest ResponseYou've already chosen the best response.0
so cant we say there 2Al n=5.7 but 2 moles n=2(5.7)

answer not correct i think i made a mistake

the periodic table i am using says atomic weight =Al M=26g/mol is this the right thing to use as M
