Vedclass · Answer

(B) Holme signals are used as a distress signal at sea. They consist of a mixture of $CaC_2$ (calcium carbide) and $Ca_3P_2$ (calcium phosphide). When this mixture is thrown into water,it produces $C_2H_2$ (acetylene) and $PH_3$ (phosphine). The $PH_3$ gas catches fire spontaneously on contact with air,igniting the $C_2H_2$ gas and producing a bright light and smoke. The reaction is: $CaC_2 + Ca_3P_2 + H_2O \rightarrow Ca(OH)_2 + C_2H_2 + PH_3$.

Holme signal can be given by using which of the following mixtures?
