One mole of calcium phosphide on reaction with excess of water give:

A

three moles of phosphine

B

one mole of phosphrinc acid

C

two moles of phosphine

D

one mole of `P_(2)O_(5)`

Text Solution

Verified by Experts

The correct Answer is:
C
`Ca_(3)P_(2)+6H_(2)O to 3Ca(OH)_(2)+2PH_(3)`
`"1 mole of "Ca_(4)P_(2)-=2"moles of "PH_(3)`
