Originally, a system contains only HI at a pressure of 1.00 atm at 520 degrees celsius. The equilibrium partial pressure of H2 is found to be 0.10 atm. Calculate Kp. 2HI(g)<-->H2(g)+I2(g). Please explain the steps so I can understand.
A sample of drinking water collected from a suburban Boston municipal water system in 2002 contained 0.45 pCi/L of radon. Assume that this level of radioactivity was due to the decay
170mL of O2 gas is collected over water at 25 degrees C and the total pressure is 742 mm Hg. The vapor pressure of water is 23.8 mm Hg at this temperature. What would the volume of the dry gas be at STP? ( hint Daltons Law and Combination Law are ..
