The black oxide of iron Fe3O4 occurs in nature as the mineral magnetite. This substance can also be made in the lab by the reaction between red-hot iron and steam according to the following equation:
3Fe+ 4H2O = Fe3O4 + 4H2
A) When 36 g of H2O is mixed with 167 g of Fe which is the limiting reactant? (H2O)
B) What mass in g of excess reactant remain? (83 g Fe)
C) What is the theoretical yield of Fe3O4? (116 g of Fe3O4)
D) If 96 grams of Fe3O4 is produced what is the percent yield? (82.8%)
Think answer is given, but need detailed explanation. Thanks
