For the Balanced Reaction:3 Mg + 1 Fe2O3
|
|
3mol Mg / 2 mol Fe
|
|
|
2 mol Mg/ 3 mol Fe
|
|
|
1 mol Fe/ 2 mol Fe
|
|
|
3 mol MgO / 2 mol Fe
|
Explanation:
Detailed explanation-1: -The limiting reactant is Fe2O3 . The theoretical yield is 30.470 g MgO .
Detailed explanation-2: -The mole ratio of Fe to Fe2O3 is 4:2.
Detailed explanation-3: -Answer and Explanation: There is a 1:2 mole ratio between Fe2O3 F e 2 O 3 and Fe . Using the mole ratio, we can now perform the calculation to determine the theoretical yield. The molar mass of Fe is equal to 55.85 grams/mole.
Detailed explanation-4: -a 3:2 molar ratio mixture of FeO and fe2o3 react with oxygen to produce a 2:3 molar ratio mixture of feo and Fe2O3.
