114 and 115 plzzz
- oxidation State of cr2o-²7

(i) Balance the following equations by oxidation number method:
(1) Cu + HNO3 → Cu (NO3)2 + NO2 + H2O)
(2) K2Cr2O7 + HCl → KCl + CrCl3 + H2O + Cl2
(ii) Give reasons for the following:
(1) HNO3 acts only as an oxidising agent while HNO2 can act both as a
reducing agent and an oxidising agent.
(2) Chlorine liberates iodine from KI solution.
How will you convert the following? (Give balanced equation.)
(1) Sodium acetate to methane
