2С⁻¹₂Н₂ + 5O⁰₂ → 4C⁺⁴O⁻²₂ + 2Н₂О⁻²

the oxidation process:
С⁻¹ - 5e⁻ = C⁺⁴ carbon is the reducing agent

the reduction process:
O⁰₂ + 4e⁻ = 2O⁻² oxygen is the oxidizer

Post your answer

Describe how oxidation and reduction involve electrons, change oxidation numbers, and combine in oxidation-reduction reactions.

Which of the following correctly describes how rate laws are determined? Rate laws can be determined from the coefficients of balanced equations. The rate law for an elementary step can only be determined from unimolecular reactions. The rate law for the overall reaction is always determined by the rate law of the fastest step. Rate laws are determined through experimentation.
