And, although they reached a height taller than Mt. Paleoelevationthe measuring of ancient mountainsisn't an exact science, but from clues in the rock (levels of sediment, size of wrinkly synclines and anticlines, fossils, oxygen isotopes in minerals) it's possible to guess at the altitude of mountains that aren't there anymore. Sulfur trioxide, SO3\mathrm{SO}_3SO3, is made industrially in enormous quantities by combining oxygen and sulfur dioxide, SO2\mathrm{SO}_2SO2.
