Is this system endothermic or exothermic, and why? * H2 + CO2 CH202 Reactant bond energies: H-H is 432 kJ/mol, C=O is 799 kJ/mol Product bond energies: C-H is 413 kJ/mol, C=0 is 745 kJ/mol, C-O is 358 kJ/mol, O-H is 467 kJ/mol It is exothermic because more energy is given off by the products versus the amount needed to break up the reactants. It is exothermic because more energy is needed to break up the reactants versus the amount given off by the products. It is endothermic because more energy is needed to break up the reactants versus the amount given off by the products. It is endothermic because more energy is given off by the products versus the amount needed to break up the reactants.

The dominant Lewis structure of furan and the two resonance structures of benzene are shown below: H K Book H What is the meaning of the double-sided arrow () connecting the two structures of benzene? Furan Benzene H It indicates that electrons in benzene rapidly change their positions corresponding to the two structures. It indicates that there are two independent coexisting forms of benzene. It indicates a chemical equilibrium between the two distinct structures. It indicates that the second structure can be obtained as a mirror image of the first one. It indicates that benzene exists in a single form, which is an average of the two structures.
