Iron Oxide + Aluminum

Iron Oxide (Ferric Oxide) + Aluminum ➜ Iron + Aluminum Oxide
Fe₂O₃ + 2Al ➜ 2Fe + Al₂O₃
molduclar weights:
Fe = 55.85
O = 15.99
Al = 26.98
Fe₂O₃ = 2•55.85 + 3•15.99 = 111.7+47.97 = 159.67
2Al = 53.96
2Fe = 111.7
Al₂O₃ = 53.96+ 47.97 = 101.93
check: 159.67+ 53.96 = 111.7+ 101.93 = 213.63

159.67 g of Fe₂O₃ + 53.96 g of Al ➜ 111.7 g of Fe + 101.93 g of Al₂O₃


Iron(II) oxide (ferrous oxide)+ Aluminum ➜ Iron + Aluminum Oxide
2Al + 3FeO ➜ 3Fe + Al₂O₃

2 mol of Al + 3 mole of FeO ➜ 3 mole of Fe + 1 mole of Al₂O₃

moldeclar weights:
Fe = 55.85
O = 15.99
Al = 26.98
FeO = 55.85 +15.99 = 71.84
3FeO = 215.52
2Al = 53.96
3Fe = 167.55
Al₂O₃ = 53.96+ 47.97 = 101.93

53.96 g of Al + 215.52 g of FeO ➜ 167.55 g of Fe + 101.93 g of Al₂O₃
check 53.96 + 215.52 = 269.48 = 167.55 + 101.93



Note:
Iron II is ferrous (forms +2 ions)
Iron III is ferric (forms +3 ions)
Iron VIII is ferrate (rare)
