Answer:The model states that electrons in atoms move in circular orbits around a central nucleus and can only orbit stably in certain fixed circular orbits at a discrete set of distances from the nucleus. These orbits are associated with definite energies and are also called energy shells or energy levels.
bohrs model and other models are really hard to understand but i hope this will help you!

Chemical reactions that absorb (or use) energy overall are called endothermic. In endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products.
Answer:
d.
Explanation:
The First law of thermodynamics states that the energy of the universe is constant.
This law explains the relationship between the energy change of a system and that of its surroundings.
The chemical system always moves toward the state with the lowest possible energy.
During the process of heat transfer, the heat transferred to or from a system's surroundings is always <u>equal in magnitude to the heat transferred to or from the system, but opposite in sign</u>
