in the molecules below, areas that have a partial negative charge are pink and areas that have a partial positive charge are blue. two molecules. the first is a yellow ball bonded above left and below left to blue balls. an area around the yellow ball is pale pink; areas around the blue balls are shaded pale blue; where the three areas overlap fades to gray. the second molecule is a yellow ball bonded to a blue ball. the area around the blue ball is pink and that around the blue ball is blue; the two areas fade to gray and then white where they overlap. the attractive force between these two molecules has most likely been produced by : a. covalent bonds.
b. dipole-dipole interactions.
c. dipole-induced dipole interactions.
d. london dispersion forces.

Iknow the answer is a but i don't know why

The table describes how some substances were formed substance 19 description formed by boiling pure water formed by combining three hydrogen atoms to every nitrogen atom formed by adding 5 g of sugar to 1 l of water formed by compressing carbon under high pressure based on the given descriptions, which substance is most likely a mixture?
