Only 3 questions will get points and brainiest a. draw the structural formula for a hydrogen molecule (h2) and an oxygen molecule (o2). remember that each line represents an electron pair being shared. b. the oxygen atoms in carbon dioxide (co2) form double bonds with the carbon atom, forming a linear molecule. draw the structural formula for carbon dioxide. the lines should be placed at the correct bond angles. c. sketch space-filling models of a hydrogen molecule (h2) and carbon dioxide ( (just need pictures of what to draw)

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)

Yes she is correct. the answer is completely correct
