Ladies and gentlemen, I want to thank you all for contributing to a robust discussion of this topic and all the various avenues that it has taken. Personally, I have never taken so much as chemistry in high school, but you have made this thread easy enough for even me to follow. I joined this forum solely on the wonderful discussion here. The suggestions, possibilities and directions here have sparked my curiosity. Although I lack the expertise to be a contributor, I am thankful that there are many here that would help me should I have a question. Life is full of questions and sometimes the answers pose even more questions. The possibilities are endless. Thankfully, it would appear that questions here are not dismissed out of hand but given thoughtful and often well directed possibilities for answers. I hope you all will continue to provide more stimulating discussion in the future!
