Question

Iron(III) oxide reacts with carbon monoxide according to the equation: Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g)Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g) A reaction mixture initially contains...

Iron(III) oxide reacts with carbon monoxide according to the equation:
Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g)Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g)
A reaction mixture initially contains 22.85 gg Fe2O3Fe2O3 and 14.26 gg COCO.

Once the reaction has occurred as completely as possible, what mass (in gg) of the excess reactant is left? m= ____ g

Answer #1

Answer is excess CO (g) will remain 2.24 g. Please see the step by step calculation provided.

Answer Fez O₂ (s) + 3 Co(9) Fe(s) + 3 C02 (8) I mole 3 mole z mole 3 mole Mol wt. of Fe2O3 = (2x55.85)+(3×16) = 159.7 g/mole
