Balanced chemical equation: C(s) + O₂(g) → CO₂(g).

Oxidation half reaction: C⁰ → C⁺⁴ + 4e⁻.

Reduction half reaction: O₂⁰ + 4e⁻ → 2O⁻².

Carbon is oxidized, it changes oxidation number from zero (in carbon element) to oxidation number +4 (in carbon dioxide).

Oxygen is reduced, it changes oxidation number from zero (in molecule of oxygen) to oxidation number -2 (in carbon dioxide).

Why does Hess's law allow you to determine the enthalpy change of a<br> reaction?
lana [24]

Enthalpy is a state function

Explanation:

The Hess's law allows us to determine the enthalpy change of a reaction because enthalpy is a state function. It does not depend on the individual path take in going from reactants to products in the reaction.

  • Enthalpy changes are the heat changes accompanying physical and chemical changes.
  • It is the difference between the heat content of product in the final state and the reactants.
  • Enthalpy changes for some reactions are not easily measurable experimentally.
  • To calculate such heat changes, we apply the Hess's law of heat summation.
  • The law states that "the heat change of a reaction is the same whether it occurs in a step or several steps".
  • The Hess's law is simply based on the first law of thermodynamics by which we know that energy is conserved in every system.
