How hot does the exothermic reaction get? I picked up a beaker of it once, and it seemed exceptionally warm.


It's -5640.9 kilojoules per mole of energy. That's about twice the amount of energy released by burning the same amount of wood (-2821.8 kJ/mol). (note: the minus sign means it's exothermic, it releases energy)

 

Therefore, I believe the technical term is "really stupid hot".

 

I've seen the reaction break untempered glass. There's a reason you're supposed to use pyrex. Well, the old formula pyrex, anyway. The new formula isn't as heat resistant <_<

Yeah, we hadd old school pyrex beakers way back when. I'm from the time when my chemistry teacher told me to touch the beaker when the reaction was happening, and I ended up grabbing it, picking it up, saying "hey, that's hot" and putting it down rather quickly. Fortunately my fire resistance protected me from any harm (true story).
