Neither have I, it's common knowledge though. Just look at a periodic table.
HA-HA! I'll be a senior next year. I'm taking chemistry AP too.
I will be in grade 11 next year, no AP classes for me yet though :(
My mod also added nitrogen by the way.
Not Really!.
Nitrogen is a coolant and a fertlizer.
Nitrogen+Plant or Vine=Growing but alot of nitrogen will kill the plant.
Nitrogen+Water=ICE
If added to much nitrogen to plant, it will kill it because of the cold temputures...
*facepalm* NITROGEN IS NOT COLD! YOU ARE BREATHING IT!
lol, yes nitrogen is usually warm, because it is gas at room temperature
