Balancing Redox Reactions: CH4 + O2 --> CO2 + H2O

Click For Summary
SUMMARY

The discussion focuses on the redox reaction between methane (CH4) and oxygen (O2), resulting in carbon dioxide (CO2) and water (H2O). In this reaction, carbon (C) in methane is oxidized, while oxygen (O2) is reduced. To determine the oxidation states, one must assign oxidation numbers to each atom involved in the reaction. This method clarifies the electron transfer process, confirming the oxidation of carbon and the reduction of oxygen.

PREREQUISITES
  • Understanding of oxidation and reduction concepts

a. CH4(g) + 2O2(g) ----------> CO2(g) + 2H2O(g)

I need to determine which is reduced and which is oxidized, I already know that C in methane is Oxidized. O2 is reduced but how can you determine that?? I know it has to do with electron transfer but I just don't see it
