The first ionization energy of a gas-phase atom of a particular element is 6.24 x 10^-19 J. What is the maximum wavelength of electromagnetic radiation that could ionize this atom?
To determine the concentration of a sodium thiosulfate solution as in this experiment, a student pipetted 25.0mL of 0.100M potassium iodate (KIO3) solution into a 125mL Erlenmeyer flask. Potassium iodide and sulfuric acid were added as in this exp..
Conductivities are often measured by comparing the resistance of a cell filled with the sample to its resistance when filled with some standard solution, such as aqueous potassium chloride. The conductivity of water is 76 mS m^?1 at 25°C
A gas is allowed to expand at constant temperature from a volume of 2.0L to 11.2 L against an external pressure of 0.750 atm. If the gas absorbs 128 J of heat from the surroundings

You could determine Ka for benzoic acid by measuring the pH of a 0.010 M solution of benzoic acid. Why is graphical method (pH vs volume of NaOH added) a better way of determining Ka
What is the subshell corresponding to the following sets of quantum numbers. An example of a subshell is 2s. A) n=3,l=2 b) n=3, l=1
In a crazy situation the Oylan Vinegar Company has 10,000 gallons of vinegar with a concentration of .114 M. It also hass a .68% acetic acid by mass
Determine the percent yield for the reaction and also find out at which point the total pressure = 188 torr.
Identify the ground state free ion terms with the spin multiplicity for the following cases: Cu2+, V3+, Cr3+, Mn2+, Fe2+, and Ni2+
the enthalpy of formation = 0? Something with standard states? But how do I know what the standard states are
If a temperature of a gas at 1.00atm and 8.00C is increased, resulting in a change of pressure, which equation would you use to calculate the new pressure.
