(a) Potassium reacts with cold water vigorously and forms potassium hydroxide and hydrogen gas.
The equation of the reaction is given as:
$2K(s) + 2H_2O(l) → 2KOH(aq) + H_2(g) + Heat$
(b) The equation of the reaction of iron with steam is given below:
$2Fe(s) + 4H_2O(g) → Fe_3O_4(s) + 4H_2(g)$
(c) Hydrogen gas is produced when dilute hydrochloric acid is added to the reactive metal.
