A. The hydrogen molecule has a structural formal that looks like this: H—H. The oxygen molecule has a structural formula that looks like this: O=O (except you should make the lines longer). When you combine the molecules, it has a structural formula that looks like this:
O
/ \
H H
b. O=C=O (again, make the lines a little longer)
c. space-filling model of hydrogen looks like this oo (circles should be touching) and the space-filling model of carbon dioxide should look like this OoO (circles should be touching)
