Basic of chemical compounds

This week we will be discussing the following examples (listed bellow) of Chemistry put to Work and Chemistry and Life.You may use these discussion prompts, or feel free to bring up your own topic for discussion that is related to this week’s reading material. Post a question that you feel needs more clarification or needs to be elaborated upon.Our bones  are a highly structured matrix consisting of both inorganic and inorganic material. About 70% of bone dry weight is made of the inorganic compound  hydroxyapatite, Ca5(PO4)3OH. The major organic components of bone, collagen fibers (protein), provide  extra-strength and allow bone to flex under stress. The blood vessels weave through the hydroxyapatite-collagen framework supplying nutrients. When severe bone fracture occurs, the orthopedic surgeon uses a bone graft, an implant of synthetic bone material, or a mixture of several  compounds within a solution of sodium phosphate to form a paste injected  into the bony area to be repaired.Please elaborate and/or describe another example of using ionic/polyatomic compounds and covalent molecules in medicine and industry.  I have included file “Ionic compounds in medicine” into D2L  as the discussion  prompt; however feel free to select different examples.  Look around you and give an example of compounds with ionic and covalent bonding; what characteristic properties make them useful for that particular application? Give an example of how breaking or forming chemical bonds can be used in industry, in everyday life, and for health profession. Explain the principle behind it. (Tip: enthalpy change) Name a  binary covalent compound(s) that does not obey the octet rule, and  describe its chemical characteristics, write the Lewis structure, etc. For  example, NO, biological messenger and air pollutant…..
