3. Consider the reaction in which CO2, and H20 form CH4 and 0, a. Write a balanced chemical equation for this reaction.
b. Include the appropriate quantity of energy (in joules) as either a
reactant or product in the chemical equation. (Hint: See Section
C.2, page 335.)
c. Explain how you knew whether to consider energy as a reactant
or product.
