When 5.0 mol Al react with 13 mol HCl, what is the limiting reactant, and how many moles of AlCl3 can be formed? (2 points) 2Al + 6HCl → 2AlCl 3 + 3 H 2
Al is the limiting reactant; 5.0 mol AlCl3 can be formed

HCl is the limiting reactant; 4.3 mol AlCl3 can be formed

Al is the limiting reactant; 7.5 mol AlCl3 can be formed

HCl is the limiting reactant; 6.5 mol AlCl3 can be formed

Well, we need to find the ratio of Al to the other reactant.

Al:HCl = 1:3

--> this means that for every 1 Al used, you have to use 3 HCl.


5*3 = 15 moles of HCl needed to fully react with 5 moles of Al. Since 13<15, HCL is the limiting reactant.


The ratio of HCl:AlCl = 3:1


13/3 = 4.3333...


The final answer is HCl is the limiting reactant with 4.3 moles of AlCl3 able to be produced so choice B.


Hope this helps!!! :)
