I found a coin..I just cant figure out how to post my screen shot of it to you. Not a techy. Lol.
It was 5/10 found in the meme section.
From that gallery I have chosen a question from one of the memes.
What are the 5 noble gases, how are they produced, and what are there main applications.
Helium is produced underground by the radioactive decay of certain heavy elements. It is used in balloons, airbags,lights, lasers, and to cool super conducting magnets.
Neon, Argon, Krypton, and Xenon are produced by the fractional distillation of liquid air. They are used mostly in lighting, neon signs, Lasers, arc welding, vacuum tubes, high voltage indicators, television tubes, and producing ultra violet lighting.
I got more!
Will that do?
Lol...not easy! But surprisingly interesting. I had to phone a friend.
You got it! Email where to send it, do you want me to hold off while you dig for more?
