Resonance structures

[Katherine Chhen 3I]

For a compound, would the best way to represent it in Lewis structures is to draw out every structure and use double headed arrows?

I think any of the possible Lewis dot structures are acceptable. If you note that there is resonance, and maybe explain why, then it should be okay to only include one of the possible structures.

[Fatemah Yacoub 1F]

I think you have to draw out all of the possible resonance structures for a compound to portray all the possible positions for the multiple bonds.

I think it depends on what the problem asks for, but in general always indicate resonance if there is any and explain why you included the structure that you did (assuming you included one in place of all of them).

Drawing all resonance structures most accurately represents what is actually happening in a lab setting, however, unless explicitly stated, I think that one would be sufficient.
Drawing them all though doesn't take that long, so to be safe, you could draw all of them.

You have to draw all of the possible Lewis structures and then figure out which one has the formal charge closest to zero.
