Question

write the chemical equation for the following reaction: the elements carbon and oxygen combine to yield the compound carbon dioxide

Answer 1

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).

Answer 2

Carbon + oxygen ---> carbon dioxide

C + O ---> CO2
