***Initially 0.50 M H2 and 0.50 M 12 are placed in a flask. When the system reaches equilibrium it is found that the concentration of HI is 0.25 M. Calculate the equilibrium constant, Keq.
H2(g) + I2(g) + 2HI(g)

Agas diffuses 1/7 times faster than hydrogen gas (h2). what is the molar mass of the gas? 100.10 g/mol 98.78 g/mol 86.68 g/mol 79.98 g/mol

In the cathode ray tube experiment, j. j. thomson passed an electric current through different gases inside a cathode ray tube in the presence of an electric field. in which two ways did this experiment change scientists’ understanding of the atom?
