Thanks, you will receive a call between 10:00am - 7:00pm IST. The addition of hydrogen or the removal of oxygen is an old, but still valid definition. no charge). At high temperature, zinc oxide, ZnO, reacts with carbon, C, to form molten zinc and carbon monoxide gas. This means that every C-H bond will decrease the oxidation state of carbon by 1.; For carbon bonded to a more electronegative non-metal X, such as nitrogen, oxygen, sulfur or the halogens, each C-X bond will increase the oxidation state of the carbon by 1. Balance the reaction of C4H10 + O2 = CO2 + H2O using this chemical equation balancer! O2 is adding hydrogen so is being reduced to make H2O.
