1. Identify the oxidation states of the elements in the reactants and products.
- Mn inMnO_2
- Mn inMnCl_2
- Cl inHCl
- Cl inCl_2
2. Determine which element increases in oxidation state (oxidizes).
- Mn changes from +4 to +2 (reduces).
- Cl changes from -1 to 0 (oxidizes).
3. The species that oxidizes is Cl (Chlorine).
Answer: c) Cl
- Mn in
- Mn in
- Cl in
