Question

How many grams of CO are needed to react with an excess of Fe₂O₃ to produce 156.2 g Fe? Show your work

Fe2O3 (s) + 3 CO (g) --> 3 CO2 (g) + 2 Fe (s)

PLEASE HELP - 20 POINTS!!

Answer 1

moles Fe = 209.7 g/ 55.847 g/mol=3.75

the ratio between Fe and CO is 2 : 3

moles CO = 3.75 x 3 /2 =5.63

mass CO = 5.63 mol x 28.01 g/mol=157.7 g
