4 0

Explanation:

Hydrogen bonds with carbon 4 times, carbon bonds with itself once, and oxygen bonds with itself 3 times.

Energy of reactants:

E = 4 * 413 + 347 + 3 * 495

= 3484kJ/mol

Answer:

Energy transferred in = 3484kJ/mol

Balance the redox reaction in alkaline medium &amp; identify the oxidizing &amp; reducing agents
Darya [45]

The balanced redox equation of the reaction is given below:

  • I⁻ + 2 MnO₄ + H₂O → IO₃⁻ + 2 MnO₂ + 2 OH⁻

The oxidizing agent is MnO₄ while the reducing agent is I⁻.

<h3>What are redox equations?</h3>

Redox equations are equations in which oxidation and reduction reactions occur together.

Redox reactions can take place in alkaline or acidic mediums.

The balanced redox equation of the reaction is given below:

  • I⁻ + 2 MnO₄ + H₂O → IO₃⁻ + 2 MnO₂ + 2 OH⁻

The oxidizing agent is MnO₄ while the reducing agent is I⁻

In conclusion, a balanced redox equation is one in which the atoms and the change in oxidation state is equal on both sides of the reaction.
