... Write the balanced equation for the reaction that occurs when methanol, CH 3OH(l), is burned in air. Solution When any compound containing C, H, and O is combusted, it reacts with the O 2(g) in air to produce CO2(g) and H2O(g). Thus, the unbalanced equation is CH3OH(l) + O2(g) → CO2(g) + H2O(g) In t ...
