~Easy Points~what does H2o stand for ?

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.

Salt in oceans comes from and of rocks

Atoms contain subatomic particles called protons and neutrons. when these protons and neutrons spilt, a lot of energy is released
