It has bent geometry, which is similar to H2O, with the same angle of 109.5 degrees between 2 single H-S bonds.
Compounds with different boiling points - b.
Only because<span> fractional distillationworks by having a temperature gradient in the column therefore different length hydrocarbons condence at different rays of different temperatures.This works because longer chain hydrocarbons have higher boiling points. </span>
An animal could be the toucan, overtime it grew a longer beak in order to access food that other birds couldn’t get. this increases the chances of successful reproduction because being able to survive longer than other birds to the beak and providing food for the babies, they can reproduce multiple times
