    Reaction of Elemental Calcium with Water is as follow,

    Ca + 2 H₂O → Ca (OH) ₂ + H₂↑

    When Sodium Metal is reacted with Water it produces NaOH and eliminates Hydrogen gas as shown in following equation,

    2 Na + 2 H₂O → 2 NaOH + H₂↑

    In both cases corresponding Hydroxides along with Hydrogen gas is produced.
