for 14:52 isnt carbon dioxide a symmetrical molecule so the dipoles cancel out so the Carbon wouldnt be electropositive

[@daviesa-levelchemistry1210]

You shouldn't really say "dipoles cancel out". A molecule has a dipole, not part of a molecule. Carbon dioxide does not have a dipole because it is symmetrical. The carbon has a partial positive charge and the oxygens have partial negative charges (Note - don't say carbon is "electropositive"- this is not the same thing as a "partial positive charge".
