Document Summary
Small molecules and the chemistry of life: oxygen has two isotopes, this plays into h2o in that those who live closer to the ocean experience heavier rain than those more inland. Iodine is a component of a vital hormone: magnesium is bound to chlorophyll in plants, elements. 6 elements that make up most of the mass of living organisms: Is produced when a solute (substance) is dissolved in a solvent (liquid) If the liquid is water, the solution is aqueous: acids and bases, acids donate h, bases accept h+ (oh-, acid-base reactions may be reversible. Ionization of strong acids and bases are almost never reversible. Ionization of weak acids and bases are somewhat reversible i. ph i. strong acids and bases completely dissociate so their ph is 0 and they have 1 m: ph scale. 1. the lower the ph the more acidic and the higher the ph the more basic a. ph.
