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.

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?

Properties seen when one one substance changes to another are known as properties

Ethanol has a heat of vaporization of 38.56 kj/mol and a normal boiling point of 78.4 c. what is the vapor pressure of ethanol at 14 c?
