Question

prefix means? endo = exo = energy released or absorbed example of this reaction i activation energy high or low?

Explanation:

The prefix "endo -" means energy is absorbed. An example of an endothermic reaction is photosynthesis where plants absorb energy from sunlight. Endothermic reactions generally have a relatively high activation energy as energy needs to be taken in to start the reaction. The prefix "exo -" means energy is released. An example of an exothermic reaction is combustion, like burning wood which releases heat and light. Exothermic reactions often have a relatively low activation energy in comparison as they tend to proceed spontaneously once initiated.

Answer:

Prefix means?	Endo =	Exo =
Example of this reaction	Photosynthesis	Combustion
Activation energy high or low?	High	Low
