Methanol, a major industrial feedstock, is made by several catalyzed reactions, such as co(g) + 2h2(g) → ch3oh(l) one concern about using ch3oh as an auto fuel is its oxidation in air to yield formaldehyde, ch2o(g), which poses a health hazard. calculate δg o at 250°c for this oxidation. × 10 kj enter your answer in scientific notation.
