Unknown without data....

Explanation:

We address the equation....

#H_2(g) + 1/2O_2(g) rarr H_2O(l) + DeltaH^@#

#DeltaH_"rxn"^@=DeltaH_f^@("water")=-285.5*kJ*mol^-1#...and when we write #DeltaH_"rxn"^@# we mean per moles of reaction as written....were we to double the given equation...to give...

#2H_2(g) + O_2(g) rarr 2H_2O(l) + DeltaH^@#

#Delta_"rxn"^@=2xx-285.5*kJ*mol^-1=??#

You will have to find the conversion factor of calories to Joules and vice versa?
