That one is up there, but let's check heat of formation...

HF gas: 63.991 KCal/mole, 3.19955 KCal/gram

MgO: 145.76 KCal/mole, 3.644 KCal/gram, but with no gaseous output.

Do you have the figures for CsF?

No I don't. I expect it to be more per mole and less per gram than HF.

I do have a figure for RbF, 133.31 KCal/mole, 1.276 KCal/gram.

But another one that ranks high per gram is Al2O3.
That one gets 389..49 KCal per mole, 3.818 KCal per gram, and 2.45% more
if you get it to be corundum crystal rather than amorphous powder.

B2O3 gets 279.81 KCal per mole, 3.886 KCal per gram.

I think BeO is also up there, probably even more per gram, but I do not
have that figure. I suspect it is the champ in energy per gram of
reactants, and misremembered by one element in the same column since
MgO is not the champ after all.

I suspect the champ is something like a mix of liquid ozone with liquid
acetylene.
Try it and report back.

Not an experiment I'd recommend. Acetylene is thermally unstable, and
cylinders of compressed acetylene contain kieselguhr

http://www.nobel.se/nobel/alfred-nob...ieselguhr.html

for exactly the same reason that nitroglycerine is only commercially
available adsorbed onto kieselguhr.

Ozone is is also thermally unstable, and I don't think that it is
commercially available at all (with or without kieselguhr).

Mixing liquid acetylene and liquid ozone could produce a very loud
report - a mixture of charcoal and liquid oxygen used to be used as a
commercial explosive.

Pure hydrogen peroxide is another nasty liquid - the British, and more
recently, the Russians have had cause to regret using it as a torpedo
fuel.

There have always been macho physicists and chemists who wanted to push
the envelope of risky experiments; Moissan, for example, who made
diamonds (not very good ones) by quenching white-hot hollow iron ingots
with carbon inside. Who was it who first produced titanium metal from
the oxide with the aid of potassium vapour?

Ozone has certainly been liquefied: it is a very deep blue, almost
black. Acetylene can't be liquefied at atmospheric pressu the solid
sublimes (turns to gas) at -84 C.

Mixing liquid acetylene and liquid ozone could produce a very loud
report -

Particularly as it would have to be done in a pressure vessel!

Was the British torpedo fuel *pure* H2O2? It would seem at first sight
unnecessary.

I remember the lox-barbecue page (which unfortunately seems to have been
taken down) warned against soaking the charcoal briquets in the liquid
oxygen.

That's a shame - I thought it was a good example of there still being
a sense of adventure out there.

People concerned with being sued.

This rated highly on the "don't try this at home" scale.
