• B)It is the total number of bonds that matters.Sometimes you create more bonds than you break and since all bonds have same amount of energy you gain or lose energy depending on the number of bonds.
• C)Some reactants have more energetic bonds than others and they will always release energy.
• D)Some products have more energy than others and they always require energy to be formed.
• E)none of the above
