Document Summary

Those ions engage in reacions that leave insoluble minerals deposits that make hard water unsuitable for many uses. Lime-soda process to precipitate ca2+ and mg2: added minerals: hydrated lime (ca(oh)2) and soda (na2co3, precipitates: caco3 and mg(oh)2, remove ca2+ and mg2+ by ion exchange column. Freshwater from the sea: solar (thermal) disillaion, reverse osmosis. Put c, h, o, n together in diferent ways to build living organisms. Foods to give you building blocks & more energy: for building and running bodies. Water (65% of your body is h2o) Geing raw materials: for synthesis & growth. Making energy ( atp adenosine triphosphate : for synthesis, growth & everyday funcions. Building cells and bodies: repair, growth, reproducion. A type of molecule that lacks an internal plane of symmetry & thus has a non-superimposable mirror image. The most common cause of chirality in molecules is the presence of an asymmetric carbon atom.
