The decomposition of hydrogen iodide to hydrogen and iodine occurs by the reaction 2H1 (g) HH2 (g) + 12 (g)
Hydrogen iodide is placed in a container at 450°C an equilibrium mixture
contains 0.5 moles of hydrogen iodide. The equilibrium constant is 0.020
for the reaction. How many moles of iodine and hydrogen are present in
the equilibrium mixture?

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

girl imma just put my comment here because i need a couple point okurrttt
