WebOverall, burning the ethanol produced from one mole of glucose results in four moles of carbon dioxide: 2 C 2 H 5 O H + 4 O 2 → 4 C O 2 + 6 H 2 O. Let's add up the moles of carbon dioxide taken in during photosynthesis, and those released during the production and combustion of ethanol. WebWhen an alcohol is dehydrated to form an alkene, one of the two carbons loses a C-H bond and gains a C-C bond, and thus is oxidized. However, the other carbon loses a C-O bond and gains a C-C bond, and thus is considered to be reduced. Overall, therefore, there is no change to the oxidation state of the molecule. top dental colleges in india
