Atomic orbitals developed using quantum mechanics describe regions of space in which one is most likely to find an describe exact paths for electron motion. give a description of the atomic structure which is essentially the same model. allow scientists to calculate an exact volume for the hydrogen atom. are in conflict with the heisenberg uncertainty principle.

No because scientist are still changing there mines today so they are not correct to this day

The purpose of a lab is to do your "expirements" the importance of the topic is so you can now what the story is about and the last one is because no one is me with my question ( what is 3 over 4 x - 9 = 27 maybe you can )

The relationship of both of them

Sounds propagates through some kind of medium. usually it's air, but it goes just as well through solid objects like walls, windows etc. a soundwave will compress the (air)molecules in front of it, and if this increased density wave hits your ears, you register it as sound. solid objects like walls are a lot denser than air, this means that they will damp a wave, but also carry it easier.
