A little bit of Chemistry

[Icicles0]

Im not saying there should be every single possible chemical compound, I just think a little here and there would be good, like for example, the Mekanism jetpack takes hydrogen as fuel and not electricity, because its a flammable gas, or in Advanced Rocketry, where you do semi-realistic fuel generation. Less made-up materials and more semi-realistic chemicals in the future might be a nice touch to the mod.
