What would the student see when the reaction takes place?

Your question is not specific enough so, I've given you a list of things that occurs, when a reaction has taken place.

It could be in the form of:

Heat or light given off or a colour change.

Hope this helps!

idk what the question is about

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
