In an experiment, 0.100 mol H2 and 0.100 mol I2 are mixed in a 1.00-L container and the reaction forms HI. If Kc = 50.0 for this reaction, what is the equilibrium concentration of HI?

I2(g) + H2(g) → 2 HI(g)

In the 1800s, one of the statements in john dalton's atomic theory was that atoms are indivisible. later experimental evidence led to the discovery of subatomic particles such as neutrons, electrons, and protons. what happened to the indivisible atom part of dalton's atomic theory, and why?
