A Vessel of of volume 22.4 L contains 2.0 mol H2 and 1.0 mol N2 at 273.15 K initially. All the H2 reacted with sufficient N2 to form NH3. Calculate the partial pressures and the total pressure of the final mixture.
Van der Waals constants can be found here. Use the ideal gas equation to calculate the pressure under the same conditions

If 3.40 mol Ca(NO3)2 reacts with 2.40 mol Li3PO4 to produce 452g LiNO3, find the limiting reactant, theoretical yield (in grams), and percent yield for the reaction.
Calculate the molar concentration of CO2 for a sample that has a pH of 6.220 and a HCO -3 concentration of 0.0020 M. For carbonic acid pKa1=6.33 and pKa2=10.35.
If 2.5 mol of ethylene oxide are decomposed at 93 degrees C, what will be the final temperature of the products? The heat capacity of the products is 110.13 J/ molC.
Present-day carbon (in living matter) gives 15.3 disintegrations per minutes per gram of total carbon. Determine the date of the volcanic eruption. Recall that the half-life of carbon-14 is 5730 y.
The temperature dependence of the equilibrium constant is given by the equation: Ln K = Ln A - delta H (standard enthalpy change)/RT. Solve for k (equilibrium constant).
