✔ 最佳答案
iron+ oxygen 係唔會出Fe3O4。iron+ oxygen 係會出FeO同Fe2O3，因為鐵(II)離子和鐵(III)離子跟氧反應後的產物唔同。
chemical formula﹕2Fe(s)+O2(g)→2FeO(s) & 4Fe(s)+3O2(g)→2Fe2O3(s)

iron steam﹕Fe(s) H2O(g)→FeO(s) H2(g)Iron acid(ionic)﹕Fe(s) 2H[ ](aq) → Fe[2 ](aq) H2(g)個reactant 係iron (II)

Fe3O4 is one of chemical formulae of some iron ore. it does exist!
