Question

Please answer both, thank you!

Rewrite this unbalanced half-reaction I−→IO3− such that it is balanced with respect to mass and charge. Do not include phases in your answer. Express your answer as a chemical equation. Use the symbol e^- for an electron.

Rewrite this unbalanced half-reaction Cl2→Cl− such that it is balanced with respect to mass and charge. Do not include phases in your answer. Express your answer as a chemical equation. Use the symbol e^- for an electron.

Answer 1

Unbalanced half reacti on is as follows Step1 Balance the atoms other than O and H IIO3 Step2: Balance O atoms by adding H2O Step3 Balance H atoms by adding H* ions Step4: Balance the charge on both si des by adding electrons Unbalanced half reacti on is as follows Step1 Balance the atoms other than O and H There is noneed to bal ance O andH Step2: Balance the charge on both si des by adding electrons Cl2 +2 e>2 Cl
