The unbalanced chemical reactions given in List I show missing reagent

1.	The unbalanced chemical reactions given in List I show missing reagent or condition (?) which are provided in List II. Match List I with List II and select the correct answer using the code given below the lists {:(,"List I",,"List II"),(P.,PbO_(2)+H_(2)SO_(4)overset(?)rarr PbSO_(4)+O_(2),1.,NO),(Q.,Na_(2)S_(2)O_(3) + H_(2)O overset(?)rarr NaHSO_(4),2.,I_(2)),(R.,N_(2)H_(4) overset(?)rarr N_(2) + "other product",3.,"Warm"),(S.,XeF_(2)overset(?)rarr Xe + "other product",4.,Cl_(2)):}
