How many moles of bonds between which pairs of atoms are broken during the combustion of 3 moles of methane (CH4) gas? Treat a double bond or a triple bond as one bonding interaction (i.e., 1 mole of triple bonds equals 1 mole of bonds). Choose one or more: A. 12 moles O–H bonds B. 6 moles of C–O bonds C. 3 moles of C–O bonds D. 6 moles of O–H bonds E. 3 moles of C–H bonds F. 6 moles of O–O bonds G. 12 moles of C–H bonds

Consider the 4 molecules below. Which 2 molecules are constitutional/structural b. isomers of each other? a and b a and c a and d Ob and c Ob and d Oc and d a. C. OH d. CO

Change the bond between the two carbon atoms in each molecule to a double or triple bond as needed to complete the structure. If the bond should remain a single bond, then you do not need to do anything to the bond. Do not change any other bonds in the molecules.

18. Which of the following statements in regards to the reaction coordinate diagram is true? A.It takes more energy to break the old bonds than energy is released in forming new bonds, resulting in an exothermic reaction. B.It takes less energy to break the old bonds than energy is released in forming new bonds, resulting in an exothermic reaction. C.It takes more energy to break the old bonds than energy is released in forming new bonds, resulting in an endothermic reaction. D.It takes less energy to break the old bonds than energy is released in forming new bonds, resulting in an endothermic reaction.
