Let's begin with the two simple molecules, wate and carbon dioxide.
We can use Jsmol to find the actual angles formed.
TRY THIS NOW!
To measure angles
Double click on center of first hydrogen atom, then drag the cursor, to the middle oxygen atom, click once, then drag to the second hydrogen atom and click twice.
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
What is the distance in angstroms from each carbon to oxygen in the CO2 molecule shown above? Jsmol uses nanometer so you need to convert to Angstroms.
1 nanometer = 10 Angstroms.
Question 12: What is the distance in angstroms from each hydrogen to oxygen in the H2O molecule?
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?
