i havea doubt in this equation which is likethis given below - i) Iron react with steam to form the metal oxide and hydrogen. 3Fe(s) + 4H2O(g) → Fe3O4(s) + 4H2(g) (1) why the there is Fe3O4 in the above equation and why not Fe2O3 (2)kindely explain me how we came to this equation (2)(a) What is the equation for the reaction of calcium and potassium in water? Calcium and potassium do not react with each other, but each decomposes water to make the relevant hydroxide with the release of hydrogen. Ca + 2H₂O → Ca(OH)₂ + H₂. 2K + 2H₂O → 2KOH + H₂.
