AP chemistry vague question

This is a repost of a question I had earlier, because I didn't provide enough details.

Here goes the question: 2CO + O2(oxygen) yields 2CO2 (carbon dioxide).

A. Draw a molecular representation of the mixture and reactants.


- That is the whole question. The problem is that I don't know what a molecular representation looks like. Please provide a link if you can.

Thank you.

I think the question might be asking for something like this:

C≡O and C≡O plus O=O yields O=C=O and O=C=O

Consider adding the nonbonding electron pairs, like this:

:C≡O:

I did CO because it's easy.
