Sample Exercise 3.1 Interpreting and Balancing Chemical Equations
... Write the balanced equation for the reaction that occurs when methanol, CH3OH(l), is burned in air. Solution When any compound containing C, H, and O is combusted, it reacts with the O2(g) in air to produce CO2(g) and H2O(g). Thus, the unbalanced equation is CH3OH(l) + O2(g) → CO2(g) + H2O(g) In thi ...
