.tg .tg-0lax{text-align:left;vertical-align:top}
| List I | List II | ||
|---|---|---|---|
| P. | \(Pb{O_2} + {H_2}S{O_4}\buildrel ? \over \longrightarrow PbS{O_4} + {O_2} + Other\,products\) | 1. | NO |
| Q. | \(N{a_2}{S_2}{O_3} + {H_2}O\buildrel ? \over \longrightarrow NaHS{O_4} + Other\,products\) | 2. | \({I_2}\) |
| R. | \({N_2}{H_4}\buildrel ? \over \longrightarrow {N_2} + Other\,products\) | 3. | Warm |
| S. | \(Xe{F_2}\buildrel ? \over \longrightarrow Xe + Other\,products\) | 4. | \(C{l_2}\) |
