9. Consider the unbalanced chemical reaction equation H3O+ +I¯+ MnO4¯ → I2 +MnO2 + H2OWhat is the balanced chemical equation for the
reaction in an acidic medium?
O 8H3O+ + 6I¯ + 2MnO4¯ –→ 3I2 + 2MnO2 + 12H2O
8H3O+ + 6I- + 2MNO4 → 3I2 + 2MNO2 + 4H2O
4H3O+ + 21 + MnO4¯ → I2 + MnO2 + 6H2O
O 4H3O+ + 21 + MnO4
→ I2 + MnO2 + 2H2O
10. Which characteristic is NOT a chemical property?
Flammability of ethanol
Luster of gold
Oxidation of iron
Decomposition of calcium carbonate
