Question

Observe the following reaction and identify the correct relationships from the following \[ xP_4(s)+yOH^{-}(aq)+zH_2O(l)\rightarrow aPH_3(g)+bH_2PO_2^{-}(aq) \] I. $x+y+z=6$ II. $x=a$ III. $x+y+z=3+a+b$ IV. $a-z+b=1$

• A. I, II, III, IV
• B. I, III, IV only
• C. II, III, IV only
• D. I, III only

Hint:

Remember: \[ P_4+3OH^-+3H_2O \rightarrow PH_3+3H_2PO_2^- \] This is a disproportionation reaction of phosphorus.
