Write equations for the reactions of
i. Iron with steam
ii. Calcium and potassium with water
i. The equation for the reaction of iron with steam:
\(xFe(s) + yH_2O (g) → X+ 4H_2(g)\)
Where x, y and X, respectively, are
ii. The equation for the reaction of calcium and potassium with water:
\(Ca(s)+2H_2O (l) → Ca(OH)_2 (aq) + Y\)
Where Y is
\(2K(s)+2H_2O (l) → 2KOH(aq) + Z\)
Where Z is
