Which of these steps happens first in the formation of sedimentary rock layers with fossils? 9. Erosion of rock

10. Particles settle out and form layers

11. Humans analyze formations to determine the age of rock

12. Sediments are distributed by river to a new location

13. Fossils form as living things are trapped in the layers

what is the question?

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
