Write equations for the reactions of
  1. iron with steam.
  2. calcium and potassium with water.


Answer :

  1. \( 2Fe(s) + 3 H_2 O(g) \)

    \( ↓ \)

    \( Fe_2 O_3 (s) + 3 H_2 (g) \)

  2. Calcium with water:

    \( Ca(s) + 2 H_2 O(l) \)

    \( ↓ \)

    \( Ca(OH)_2 (aq) + H_2 (g) \)


    Potassium with water:

    \( 2K(s) + 2 H_2 O(l) \)

    \( ↓ \)

    \( 2KOH(aq) + H_2(g)+ heat energy \)
