For this 2: reason, it is often used as a fuel in high performance racing cars. The combustion of methanol has the balanced, thermochemical equation CH,OH(g) + 0,(g) → CO,(g) + 2H,O(1) AH = –764 kJ How much methanol, in grams, must be burned to produce 629 kJ of heat? 26.33 mass: TOOLS x10 about us careers privacy policy terms of use contact us help 5:14 PM 12/11/2020 50

12:27 12-2 Analyzing Data... NAME Energy (kJ) NAME 1000 Many chemical reactions involve a change in energy. When the energy of the reactants is greater than the energy of the products, the reaction gives off heat and is exothermic. When the energy of the products is greater than that of the reactants, the reaction must absorb energy from the surroundings to occur and is endothermic. If the intermediate stage (the activated complex) is of a higher energy, then the reaction can only take place if the reactants are given an initial energy input (the activation energy). The graph shows energy diagrams that indicate how the energy changes as three reactions occur.
