If It Takes Energy to Break Bonds and You Gain

question 118

Multiple Choice

If it takes energy to break bonds and you gain energy in the formation of bonds,how can some reactions be exothermic while others are endothermic?

• A)It is the total amount of energy that matters.Sometimes some bonds are stronger than others and so you gain or lose energy when you form them.
• 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

Definitions:

Horizontal Cells

Neurons located in the eye's retina that help integrate and regulate the input from multiple photoreceptor cells, contributing to visual processing.

Bipolar Cells

Specialized neurons in the retina that play a critical role in visual signal processing, connecting photoreceptors to ganglion cells.

Amacrine Cells

Amacrine cells are interneurons found in the retina that play a role in the modulation and integration of visual information as it is passed from the retina to the brain.

Wavelength

Wavelength is the distance between successive crests of a wave, typically used in the context of electromagnetic waves, sound waves, or other waves.
