Document Summary

60 ml water in ocean, 3. 5% salt (off coast of new jersey but also mostly worldwide) Galapagos iguanas everywhere: 1 mole sample of water from galapagos; 3. 8% salt, warmer thus water evaporates, increases salt concentration, not much fresh water flowing in to the ocean to dilute it. Remove electrons to get calcium (2+), magnesium (2+), sodium (1+) Caso4 gypsum (a mineral sands, soft chalk) ca2+ + so4. Mgso4 epson salts (foot soak) mg2+ + so4. Ca(hco3)2 calcium bicarbonate [decomposes into] caco3 (limestone) + co2 + h2o. Other crystallizations: dolomite mgco3 and caco3, inside is hgs (highly toxic) The weight difference between an element and its ion is much less than micrograms. (the weight of an electron is hardly measurable!) Proton in the nucleus is surrounded by electrons equal to the charge in the nucleus. Na (reacts with water catches fire) atomic number of 11.
