Fe2o3 + co → fe + co2 if 2 moles of fe2o3 react with 9 moles of co, how many moles of each product are formed?

The number of  moles    of each  product  that are  formed  if  2 moles  of Fe2O3 react  with  9 moles  of CO is  4 moles of Fe   and  6 moles   of CO2

    Explanation

write a balanced  chemical  reaction

that is  FeO3 + 3 CO → 2 Fe + 3CO2

 2  moles  of Fe2O3  reacted  with  3 x2=6  moles of Co to form Fe and CO2 therefore CO  was in excess  and  Fe2O3  was limiting reagent.

use  the mole ratio  to determine the moles of each product.

that is the   mole ratio 0f Fe2O3 : Fe  is 1:2  therefore the moles of Fe = 2x2=4 moles

the mole ratio  of  Fe2CO3 :  CO2   is  1: 3 therefore the moles of Co2 = 2 x3= 6 moles
