Directions: Determine if the following chemical reactions are oxidation-reduction reactions or not. If the chemical reaction is NOT a redox reaction, write NONREDOX; otherwise, balance it by oxidation number method and determine the oxidizing and reducing agents. Show your solution following the step-by-step process of the said method and do consider the criteria given below. 1. K₂Cr2O4 + H₂O2 + HCl → KCl + CrCl3 + O2 + H₂O Redox or Nonredox? If REDOX: Balanced equation: Oxidizing agent: Reducing agent:
