Is the osmosis egg challenge a chemical reaction? If so, was the stored energy in the reactants released (exothermic) or absorbed (endothermic) during this physical change?
If not, was energy released (exothermic) or absorbed (endothermic) by the molecules during this physical change?

Answers

Answer:

Answer is C because in exothermic reactions, energy releases.

in Cellular respiration,

ATP+H20 (water) = ADP+ Pi + Energy

So celullar respiration is exothermic and releases energy

Answer:

yes it is

Explanation:

because what ever you mix in it it would explode and give a chemical reaction
