PbSO ₄+ O ₂+ other product & P & NO B. & Na ₂ ~S ₂ O ₃+ H ₂ O ? NaHSO ₄+ other product & Q & I ₂ C. & N ₂ H ₄ ? ~N ₂+ other product & R & Warm D
Options
- Aa-p;b-r;c-q;d-s;
- Ba-p;b-r;c-q;d-s;
- Ca-r;b-s;c-q;d-p;
- Da-r;b-q;c-s;d-p;
Correct answer
C. a-r;b-s;c-q;d-p;
Step-by-step solution
2PbO 2 + 2 H 2 SO 4 ⟶ Warm 2PbSO 4 + O 2 + 2 H 2 O Na 2 S 2 O 3 + H 2 O ⟶ + Cl 2 NaHSO 4 + HCl N 2 H 4 ⟶ + I 2 N 2 + 4 HI Xe F 2 ⟶ +NO Xe + NOF
