One series of lines of the hydrogen spectrum is caused by emission of energy accompanying the fall of an electron from outer shell to the fourth shell. The lines can be calculated using the Balmer-Rydberg equation: 1/^ = Roo [1/m^2 - 1/n^2] Where m = 4, Roo= 1.097 x 10^-2 nm-1, and n is an integer greater than 4. Calculate the wavelengths in nanometers and energies in kilojoules per mole of the first two lines in the series. In what region of the electromagnetic spectrum do they fall?
In an experiment using a temperature probe, is there a way to estimate the heat absorbed by the temperature probe? Explain how.
On hot days, you may have noticed that potato chip bags seem to inflate even thougt they have not been opened. if i have a 250 mL bag at a temperature of 19 C and i leave it in my car that has a temperature of 60 C, what will the new volume of the..
A saturated solution of iron(II) hydroxide at 25°C contains 1.0 x 10-5 M Fe2+ ions. Determine the ?G° for the solution at this temperature.
Solid aluminum acetate is slowly added to 75.0 mL of a 0.0536 M sodium phosphate solution. The concentration of aluminum ion required to just initiate precipitation is
Calculate the density of a block.
What mass of NaOH is needed to precipitate the Cd2+ ions from 48.0 mL of 0.500 M Cd(NO3)2 solution?
The bp of the solution was 104.3C when 40 g was dissolved in 150mL of water. I lose points if I am more than 5% off. Any ideas what the actual substance might have been? Keep in mind this is a college gen chem lab.
What is the virial pressure of 0.693 moles of O2S gas at 350K in a 1000 cm3 container, given B = -7 cm3mol1-? atm (Report to 2 significant figures.)
Compounds like CCl2F2 are known as CFCs and were once widely used as refrigerants. Breaking down of these molecules in the atmosphere releases Cl atoms
Compare this temperature with the true boiling point of N2. The boiling temperature is the temperature at which the areas under the two van der Waals loops are equal. In order to solve the problem
A system equilibrium at 25 degrees Celsius in a 1.0L container was found to contain 0.0568 moles of BrCl, 0.0216 moles of Br2, and 0.0216 moles of Cl2. If 0.020 moles of BrCl is added to this system, determine the new equilibrium concentrations.
Why is this only an approximation? Under what conditions can the selectivityremain temperature-independent?
