Question

Iron (iii) oxide reacts with carbon to give iron and carbon monoxide.
Fe2O3(s) + 3C (s)....... 2Fe (s) + 3CO (s)

How many grams of CO are produced when 36.0 g of C reacts ?

Answer 1

Fe₂O₃(s) + 3C (s) --> 2Fe (s) + 3CO (s) 

The mass of CO produced in the reaction can be calculated using th following equation:

m(CO) = [m(C) × 3 × Mr(CO)] / [3 × Mr(C)] = 36.0 g × 28.01 g/mol / 12.01 g/mol = 84.0 g

Answer: 84 g
