Bioluminescence is a chemical reaction that takes place in a living organism when the organism emits light. Bioluminescence doesn't consume or produce heat, hence it can be neither endothermic nor exothermic reaction. It emits a heatless light not heat.
For bioluminescence, it could be said that it is an exoenergetic reaction because it uses energy from a chemical reaction to produce light.
Yes, depending on the thickness.
I honestly don’t know the answer to this one
The density of a substance is equal to its mass divided by its volume. In this case, it is equal to 693.8 g divided by 92.5 mL. The density of the substance is then equal to 7.50 g/mL. It has 3 significant figures because in division, the answer will have the least number of significant figures from the given.
Answer:
Chemical reaction, not physical
