Fe + 2HCl = FeCl2 + H2 ↑ (Interaction of iron and hydrochloric acid).
FeCl2 + 2KOH = Fe (OH) 2 + 2KCl (Exchange reaction between an iron salt with an alkali, in this case with potassium hydroxide).
2Fe (OH) 2 + 3O2 + 6H2O = 4Fe (OH) 3 (Compound reaction, one of the stages of iron rusting).
Fe (OH) 3 = Fe2O3 + H2O (Decomposition on heating, one of the stages of iron rusting).
Fe2O3 + 3CO + 2Fe + 3CO2 (Reduction of iron from ore, one of the industrial methods for producing iron).
