Assignment:
Balance the redox equations and give the half-cell reactions and identify the oxidizing agent, species oxidized, reducing agent, and species reduced.
In an acidic solution: CrO4^2-(aq)+ Cl-(aq)--> Cr^3+(aq) +HClO2(aq)
In an acidic solution: Fe^2+(aq) + MnO4-(aq) --> Fe^3+(aq)+ Mn^2+(aq)
In acidic solution: NH4+(aq) + NO3-(aq)--> N2O(g)
In basic solution: N2H4(aq) + Cu(OH)2(s) ---> N2(g) + Cu(s)
In basic solution: Ca(OH)2(aq)+ C(s) + ClO2(g)--> CaCO3(s) +ClO2-(aq)
Provide complete and step by step solution for the question and show calculations and use formulas.
