What reaction would you get from francium and water in outer space and what if you added hydrogen to the experiment as far as being used for fuel for travel
I do not understand why you would want to react Francium and water in space or anywhere else. It is highly radioactive and very expensive to make. It will oxidize in air and react vigrously in water, just as sodium and potassium do.
The reaction would be
2 Fr + 2 H2O -> 2 FrOH + H2
H2 would be given off as a product, so why would you add more?
In outer space, for interplanetary missions, chemical rockets are not a wise choice. Their specific imopluse it low compared to electrical thrustors. You have to carry too much mass along for use as a propellant.
