274. Which of the following reactions are redox reactions?
BiOCl HCl → BiCl3 H2O
FeSO4 KClO3 H2SO4 → Fe2(SO4)3 KCl H2O
Na3AsO3 I2 H2O → Na3AsO4 HI
For redox reactions, write electronic equations. Arrange the coefficients in the reaction equations. For each reaction, determine the equivalent of the oxidizing agent and reducing agent.
