Set up balanced reduction and oxidation reactions for the following reactions: a) Chlorine, Cl2 , disproportionates to chloride, Cl , and chlorate, ClO  3 , in alkaline medium

A is a molecule with a distorted tetrahedral structure that forms a red, volatile, and corrosive liquid at  room temperature. When 465 mg of A dissolves in water, the resulting solution is acidic and  requires 6.0 mmol Ba(OH)2 to neutralize it. Meanwhile, a precipitate B forms. B cannot dissolve in  dilute HClO4, but the solution changes from colorless to orange, indicating that some reaction  happened. After reaction, C is the major product in solution and D is the major product in the solid  phase. Excessive KI is added to the orange solution C, followed by titration with thiosulfate (9.0  mmol is used). At the end point, the solution is green. A green precipitate E forms when this solution  is neutralized with base. Excessive base will dissolve E to form ion F. A yellow ion G forms when F is  boiled with H2O2. G turns into C when acid is added. C reacts with H2O2 under acidic conditions to  form an unstable structure H. H decomposes into ion I and a gas J. Identify A – J. 

Write the expression for the analytical concentration of NH₃ in the dissociation of zinc–ammonia complex, Zn(NH₃)₃²⁺.

Resolve the concentration of 10 mL of 0.1 N hydrochloric acid accidentally added with 90 mL of distilled water. Answer with solution please. Thank you.

The common forms of nitrogen and phosphorus are N₂(g) and P₄(s) respectively. Account for the difference in terms of the single and multiple bond enthalpies.

I would like to know how to explain, thanks!!
