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!
Answer:
Energy added to solid water will turn it into liquid water; add energy into liquid water and it will be turned into water vapor.
Explanation:
Adding energy is basically adding heat; the more heat, the more excited the molecules of H2O gets. In solid water, the molecules aren't really moving because they don't have a lot of energy, so it is solid. In liquid water (which is water in room temperature), it has a medium amount of energy; the molecules aren't stuck together but it isn't completely dispersed, so it is in liquid form. However, in water vapor, the energy becomes very high and the molecules are excited. The hydrogen bonds holding the molecules together break and the water is released as a vapor.
Here you are! I hope it helps, and also for the ones I put a red ‘x’ it depends on how you round it.
It’s C. 4.68 N
I hope this helped out! Have a nice day :)
Answer:
What Julie did wrong is that she did not read the instructions for her lab of wait for her instructor to allow her to get started.
Explanation:
it is essential to know what you are doing in a science lab because you can be injured seriously if you don't stop and take time to read and listen to you instructors directions.
