Chemistry week 6

1.  Ca 25 is the 5th most common element found in the earths crust.   Calcium signals many chemical processes in the body and is essential to human life.  It is found in bone, teeth, and shells.  It is a silvery metal that is soft and reactive.  It is the lightest of  the alkali earth metals and is extracted through electrolysis from calcium chloride.  Calcium reacts with water and forms

2.  The Alvarado's link would not work for me.  I find the Hypothesis interesting and think I understand it, but feel it would ground into solid knowledge if I was spending the time making chemical formulas and using his theory.  

3. Molecular Medicine scares me a bit.  It feels like we have entered a sci-fi novel and having read a lot of those I know that they don't always end well.  When you're using such small non-technology its so hard to know what the effects will end up being on the cells.  Is there a chance of the technology going haywire?  How can the destruction be limited to cancer cells and not other cells as well?  What happens to the machines once they've done their job?  These are the many reasons that I don't think I'll be signed up to be injected with micro machines anytime soon.
