Pressure and volume are inversely related (constant T, temperature, and n, # of
moles of gas).
PV = k (k is a constant for a given sample of air at a specific temperature)
A sample of helium gas occupies 12.4 L at 23C and 0.956 atm. W
What is meant by the term chemical bond?
Why do atoms bond with each other to form molecules?
How do atoms bond with each other to form molecules?
The ability of an atom in a molecule to attract shared electrons to itself.
For a molecule HX, the relative
Device used to measure atmospheric pressure.
Mercury flows out of the tube until the pressure of the column of mercury
standing on the surface of the mercury in the dish is equal to the pressure of the
air on the rest of the surface of the merc
You are holding two balloons of the same volume. One contains helium, and one
contains hydrogen. Complete each of the following statements with different or the
same and be prepared to justify your answer.

Four Pairs of Electrons
Steps for Predicting Molecular Structure Using the VSEPR Model
1. Draw the Lewis structure for the molecule.
2. Count the electron pairs and arrange them in the way that minimizes repu
A model is an approximation and is destined to be modified.
So far we have considered what happens, but not why.
In science, what always comes before why.
