(a) Complete the following chemical reaction equations:(i) AgCl(s) + N

1.	(a) Complete the following chemical reaction equations:(i) AgCl(s) + NH3(aq) →(ii) P4(s) + NaOH(aq) + H2O(l) →(b) Explain the following observations:(i) H2S is less acidic than H2Te(ii) Fluorine is a stronger oxidising agent than chlorine(iii) Noble gases are the least reactive elements
Answer» (a) (i) AgCl + 2NH3 → [Ag (NH₃)₂]⁺Cl^– (ii) P₄+ 3NaOH + 3H₂O → PH₃+ 3NaH₂PO₂ (b) (i) This is because bond dissociation enthalpy of H–Te bond is less than H–S as the size of Te is larger than S. (ii) Fluorine is a stronger oxidising agent than chlorine due to low dissociation enthalpy of F–F bond and high hydration enthalpy of F^– ions. (iii) Noble gases are the least reactive elements due to fully filled outermost shells and zero electron gain enthalpy.

Answer»

(a) (i) AgCl + 2NH3 → [Ag (NH₃)₂]⁺Cl^–

(ii) P₄+ 3NaOH + 3H₂O → PH₃+ 3NaH₂PO₂

(b) (i) This is because bond dissociation enthalpy of H–Te bond is less than H–S as the size of Te is larger than S.

(ii) Fluorine is a stronger oxidising agent than chlorine due to low dissociation enthalpy of F–F bond and high hydration enthalpy of F^– ions.

(iii) Noble gases are the least reactive elements due to fully filled outermost shells and zero electron gain enthalpy.
