Which statement about Niels Bohr’s atomic model is true? Higher orbits have lower energies.
Each orbit has a specific energy level.
Electrons can exist in any energy level.
Orbits close to the nucleus have no energy.

im pretty sure its b

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.

here are some of the ways in which chemical and nuclear reactions differ.
