1.	One mole of calcium phosphide on reaction with excess water gives(a) one mole of phosphine(b) two moles of phosphoric acid(c) two moles of phosphine(d) one mole of phosphorus pentoxide
Answer» (c) Ca₃ P₂+ 6H₂O →3Ca(OH)₂+ 2PH₃; i.e 2 moles of phosphine are produced from one mole of calcium phosphide Ca3P2+6H2O⇒3Ca(OH)2+2PH3 1 mol of Ca3P2=2 moles of PH3 It shows that one mole of calcium phosphide on reaction with excess of water gives 2 moles of phosphine. Hence, Option C is Correct

One mole of calcium phosphide on reaction with excess water gives(a) one mole of phosphine(b) two moles of phosphoric acid(c) two moles of phosphine(d) one mole of phosphorus pentoxide

Answer»

Ca3P2+6H2O⇒3Ca(OH)2+2PH3

1 mol of Ca3P2=2 moles of PH3

It shows that one mole of calcium phosphide on reaction with excess of water gives 2 moles of phosphine.

Hence, Option C is Correct
