Fe + O2 ----------> Fe2O3 balance the equation |
|
Answer» 4Fe + 3O2 ----> 2Fe2O3Explanation:1. Balance the Fe first by MULTIPLYING with 2.i.e 2Fe + O2 ---> Fe2O32. Then balance the oxygen by multiplying 3/2.i.e 2Fe + (3/2)O2 ---> Fe2O33. To make sure that all the coefficients are WHOLE NUMBERS multiply the reactants and products with 2.i.e 2(2Fe + (3/2)O2) ---> 2(Fe2O3) => 4Fe + 3O2 ---> 2Fe2O3 |
