Calculate the partial pressure of each gas in the container. Express the pressure values numerically in atmospheres, separated by commas. Enter the partial pressure of methane first, then ethane, then propane.
Determine the molar solubility of Mg(OH)2(s) (Ksp = 7.1 x 10-12) in a 0.050 M solution of NaOH both neglecting activities and including activities. Compute the percent relative error introduced to the calculation when you omit activities.
Why is it important that all determinations of acid-base titrations be done at the same temperature
Calorimetry is a method used to measure enthalpy, or heat, changes that occur during chemical processes. Two common calorimeters are constant-pressure calorimeters and constant-volume (or "bomb") calorimeters
