Silly (Former) Chemistry Nerd Questions
Back when I was in college, I used to study this stuff, but I've forgotten...
1. CaSO4 = chalk = wrong?!
2. "Silicon and oxygen make concrete, bricks, and glass..." Glass? Really? How?
3. Is it really true that more than half our our body is OXYGEN, not CARBON?
Thanks for the info (and not laughing at me).
