What is the relationship between molecular modeling and mathematics?
(-- See Part I if this is your first page view.)
Let's begin with the two simple molecules, wate and carbon dioxide.
We can use JMol to find the actual angles formed.
TRY THIS NOW!
To measure angles
Double click on center of first atom, once on middle atom, twice on atom three.
Now try using
to measure the distances!
To measure distance
Label the atoms: Right mouse button -->Labels --> With atom names
Double click on hydrogen (H33) then drag to oxygen (O28) -- double click again
Question 13: What is the distance from the tip of one hydrogen in a water molecule to the other hydrogen? (Click first on one hyrogen atom then the other.
If 1 angstrom = 10 -10 meters, approximately how many molecules of would it take to make a line of water 1 centimeter long?
