Hydrogen iodide, HI, is formed in an equilibrium reaction when gaseous hydrogen and gaseous iodine gas are heated together. First, write the equilibrium reaction and balance it. The volume of the reactor is not changing during the process. Now, if 24.2 g of H2 and 24.2 g of I2 are heated, they form 9.9 g of hydrogen iodide, what mass of hydrogen remains unreacted? No unit is needed. At least 3 sig fig is needed. Avoid too much rounding! You...
