P_(4)+NaOH to PH_(3) uarr+NaH_(2)PO_(2)

Two substances P_(4) & O_(2) are allowed to react completely to form mixture of P_(4)O_(6) & P_(4)O_(10) leaving none of the reactants .Using this information calculate the moles of P_(4)O_(6) and P_(4)O_(10) in the final mixture when the following amounts of P_(4) & O_(2) are taken. P_(4) + 3O_(2) to P_(4)O_(6) P_(4) + 5O_(2) to P_(4)O_(10) (i) If 1 mole P_(4) & 4 mole of O_(2) (ii) If 3 mole P_(4) & 11 mole of O_(2) (iii) If 3 mole P_(4) & 13 mole of O_(2)
