Assertion Calcium acetylide is `CaC_2`
Reason `CaC_2` is a calcium salt of acetylene.

Assertion : Formula of calcium oxide is CaO. Reason : Symbol of calcium is Ca and its charge is +2 and charge on oxide is -2.

Assertion : Acetylene on reacting with sodamide gives sodium acetylide and ammonic. Reason : sp- hybridised carbon atoms of acetylene are considerably electronegative.

Assertion : Acetylene on reacting with sodamide gives sodium acetylide and ammonia. Reason : sp hybridised carbon atoms of acetylene are considerably electronegative .

Assertion : Calcium carbide on hydrolysis gives methane. Reason : Calcium carbide contains C_2^(2–) anion.

Assertion : Calcium carbide on hydrolysis gives methane. Reason : Calcium carbide contains C_2^(2–) anion.

Assertion: Calcium is a constituent of cell wall. Reason: Calcium is required in mitotic division.

Acetylene is obtained from CaC_2
