Document Summary

The learning goals of this topic are to: Chem 181 world of chemistry: foods: describe the difference between the elemental and ionic form of minerals. Mineral found in abundant in the ocean -> large variability of soluble minerals is dissolve in ocean. Ex: 3. 5% minerals were found in most ocean. In galapagos -> taken 1 mole of water -> 3. 8% minerals in that 1 mole of water of the ocean. Caso4 -> gypsum ; mgso4 -> epsom salt ; nacl -> table salt (form from 2 toxic elements na and cl2) Ca(hco3)2 -> caco3 + co2 + h2o (caco3 -> limestone) Dolomite (rock form minerals) -> source of magnesium and calcium -> only very very small amount of iron. Complain that i may contain arsenic or mercury or aluminium or lead as trace elements. Vertical column -> in general -> materials or element that have somewhat similar properties. The atomic nb -> refer to the nb of proton.
