CaH 2+2 H 2 O longrightarrow Ca ( OH )2+2 H 2 uparrow Ca +2 H 2 O longrightarrow Ca ( OH )2+ H 2 uparrow Calcium carbide with water gives acetylene and calcium oxide with water gives calcium hydroxide.

Q. Hydrogen can be ottained from water, by the action of water on
(1) calcium carbide
(2) calcium hydride
(3) calcium oxide
(4) calcium

1, 2 and 3 are correct

1 and 2 are correct

2 and 4 are correct

1 and 3 are correct

$C a H_{2} + 2 H_{2} O ⟶ C a (O H)_{2} + 2 H_{2} ↑$
$C a + 2 H_{2} O ⟶ C a (O H)_{2} + H_{2} ↑$
Calcium carbide with water gives acetylene and calcium oxide with water gives calcium hydroxide.
