Al(s) + Fe3 O4 = Fe (s) + Al2 O3(s)
calculate how many grams of iron can be produced when 14.0g of Al are combined with excess FeO4.
The Attempt at a Solution
I know that I need to balance the solution which is:
8Al(s) + 3Fe3 O4 = 9Fe (s) + 4Al2 O3(s)
8al + 3fe3o4 = 9fe + 4al2 o3
can someone please help me on this I can't get any further on finding the excess on using the net or balance ionic equation. I cant really cancel any out that are the same on both side. please help.
