Solution: Mining companies use this reaction to obtain iron from iron ore: Fe2O3 (s) + 3CO (g) → 2Fe (s) + 3CO2 (g) The reaction of 182 g of Fe2O3 with 83.4 g of CO produces 72.5 g of Fe. Identify the limiting reactant. (i) Fe2O3 (ii) CO

Problem

Mining companies use this reaction to obtain iron from iron ore: 

Fe2O3 (s) + 3CO (g) → 2Fe (s) + 3CO2 (g) 

The reaction of 182 g of Fe2O3 with 83.4 g of CO produces 72.5 g of Fe. 

Identify the limiting reactant. 

(i) Fe2O3 

(ii) CO
