Iron(III) oxide reacts with carbon to give iron and carbon monoxide; Fe2O3(s)+3C

Question

Iron(III) oxide reacts with carbon to give iron and carbon monoxide; Fe2O3(s)+3C(s)-->2Fe(s)+3CO(g). a) How many grams of C are required to react with 2.50 mol of Fe2O3? b) How many grams of CO are produced when 36.0 g of C reacts? c) How many grams of Fe can be produced when 6.00 g of Fe2O3 reacts?

Explanation / Answer

Fe2O3(s)+3C(s)===>2Fe(s)+3CO(g). a) How many grams of C are required to react with 2.50 mol of Fe2O3? 2.50 mool Fe2O3 (3 mol C/1 mol Fe2O3)*(12 g C/ 1mol C) 90g C b) How many grams of CO are produced when 36.0 g of C reacts? 36.0 g C*(1 mol C/12 g C)*(3mol C/3 molC)*(28g CO/1 molCO) 84 g CO c) How many grams of Fe can be produced when 6.00 g of Fe2O3 reacts? 6.00g Fe2O3*(1 mol Fe2O3/ 159.69 g Fe2O3)*(2 mol Fe/1 mol Fe2O3)*(55.85 g Fe/1 mol Fe) 4.20g Fe
