Answer to Question #295625 in General Chemistry for cols

Question

The reaction between calcium carbide (kalburo, CaC₂) and water forms acetylene (C_{2}*H_{2}) and calcium hydroxide [Ca(OH) 2 ].

Answer 1

CaC₂+H₂O→C₂H₂+Ca(OH)₂

1 mole of CaC₂ produce 22.4 litres of acetylene on STP.

1 mole of CaC₂→22.4 litres acetylene.

0.2 moles CaC₂→0.2×22.4=4.48.litres

Acetylene=4.5 litres.

Therefore,4.5 litres of acetylene is produced.
