Question

question 12 (1 point)
which type of reaction releases energy spontaneously?
o a dehydration synthesis
b hydrolysis
o c endothermic
d exothermic

Explanation:

• Dehydration synthesis: It is a reaction that builds larger molecules and requires energy input (consumes energy, not releases).
• Hydrolysis: It breaks down molecules using water. While it can release energy in some cases (like breaking certain bonds), it's not the most general - term for energy - releasing spontaneous reactions.
• Endothermic: By definition, endothermic reactions absorb energy from the surroundings.
• Exothermic: Exothermic reactions are characterized by the release of energy (usually in the form of heat) spontaneously.

Answer:

d. Exothermic
