How can I solve this? Thank you in advance!! Draw all the other resonance structures. Show the flow of electrons (arrows). Draw all lone pares as well. Show which ones are most impactful (most stable).

Substance a is a nonpolar liquid and has only dispersion forces among its constituent particles. substance b is also a nonpolar liquid and has about the same magnitude of dispersion forces among its constituent particles. when substance a and b are combined, they spontaneously mix.
