Hydrogen iodide can decompose into hydrogen and iodine gases. 2 HI(g) f H2(g) + I2(g) Kp = 0.016 If 0.820 atm HI(g) is sealed in a flask, what is the pressure of each gas when equilibrium is established
a) H2 (g) + Br2 (g) â?" 2 HBr (g) + heat [0.513] [0.62] [0.346] b) N2O4 (g) + heat â?" 2 NO2 (g) [0.0325] [0.022] c) NH4SH (g) â?" NH3 (g) + H2S (g) + heat [0.027] [0.0234] [0.209] Calculate Ke for the following (equilibrium concentrations give..
A cylinder of compressed gas rolls off a boat and falls to the bottom of a lake. Eventually it rusts and the gas bubbles to the surface. A chemist collects a sample of the gas with the idea of trying to identify the gas.
