Solution: When FeCl3 is ignited in an atmosphere of pure oxygen, this reaction takes place.4FeCl3(s) + 3O2(g) → 2Fe2O3(s) + 6Cl2(g)If 3.00 mol of FeCl3 are ignited in the presence of 2.00 mol of O 2 gas, how much of which reagent is present in excess and therefore remains unreacted?a) 0.33 mol FeCl3 remains unreactedb) 0.67 mol FeCl3 remains unreactedc) 0.25 mol O2 remains unreactedd) 0.50 mol O2 remains unreacted

Problem

When FeCl3 is ignited in an atmosphere of pure oxygen, this reaction takes place.

4FeCl3(s) + 3O2(g) → 2Fe2O3(s) + 6Cl2(g)

If 3.00 mol of FeCl3 are ignited in the presence of 2.00 mol of O 2 gas, how much of which reagent is present in excess and therefore remains unreacted?

a) 0.33 mol FeCl3 remains unreacted

b) 0.67 mol FeClremains unreacted

c) 0.25 mol Oremains unreacted

d) 0.50 mol O2 remains unreacted
