I was reading howstuffworks.com on landmines, and it gave the chemical composition of dynamite:
Now I understand the basics of explosives is that they should contain their own oxygen, and some nitrogen, and carbon. What I don't get is the second part of this compound. To me it looks like O-N-O-O. Why would it be written ONO2 instead of NO3? Obviously they're not the same thing, but why? Is it written like that to describe the physical shape of the molecule?
