[SOLVED] Last Stoich I swear
When FeCl3 is ignited in an atmosphere of pure oxygen, this reaction takes place
4FeCl3 + 3O2 -> 2Fe2O3 + 6Cl2
If 3.00 mol of FeCl3 are ignited in the presence of 2.00 mol of O2 gas, how much of which reagent is present in excess and therefore remains unused?
Now I don't know where to go from here. Obviously solve for the limiting reagent. Then I need some type of ratio to solve for how many mol are used :grumpy:
