write ground-state electron configurations for these ions, which play important roles in biochemical processes in our bodies. (Use a noble gas core abbreviation) Na^+, Mg^2+ Cl^- K^+
A piece of lithium metal was added to a flask of water on a day when the atmospheric pressure was 757.5 Torr. The lithium reacted completely with the water to produce 250.0 mL of hydrogen gas, collected over the water at 23°C, at which temperature..
Calculate the pH of this buffer if it is .10 M HC2H3O2 and .10 M C2H3O2-. The Ka for CH3COOH is 1.8x10^-5.

What are the concentrations of barium and sulfate ions in this solution? Assume only SO42- ions (no HSO4? ) are present
determine the partial pressure and the total pressure in a 2.50 L vessel containing the following mixture of gases at 17.8 degrees celsius
What is the boiling point of a 0.800 molal solution of sugar in water? Kb = 0.512C/m for water. Sugar does not dissociate in solution and pure water boils at 100C.
Standard Spectrophotometry experiment. I have absorbance, path length (1) and I need to determine the concentration of an unknown based on my calibration cure. I need the Extinction Coefficient. Is that just the slope of by calibration curve? Or i..
