The chart below lists six stars. Research the luminosity, distance from Earth, and surface temperature of each star. Make sure to research credible sites, such as nasa. gov, to complete your chart. Distances should be given in light years and temperatures given in Kelvin. Luminosity (L) is how bright something is in human eyesight. As you conduct your research, look for the luminosity of each star relative to the Sun. (Therefore, the luminosity of the Sun is 1). If your sources give a fraction for luminosity, convert the fraction into a decimal number. Use your research to complete the chart. Font Sizes

You mix the pks of succinic acid are 4.21 and 5.64. how many gramsa graduate student at sdsu wants to measure the activity of a particular enzyme at ph 4.0. to buffer her reaction, she will use a buffer system based on one of the acids listed below, which acid is most appropriate for the experiment? of monosodium succinate (fw = 140 g/mol) and disodium succinate (fw = 162 g/mol) must be added to 1 l of water to produce a solution with a ph 5.28 and a total solute concentration of 100 mm? (assume the total volume remains 1 liter, answer in grams monosodium succinate, grams disodium succinate, respectively.) volumes of 0.05 m nah2po4 and 0.05 m na2hpo4 (pk's for phosphoric acid are 2.15, 6.82 and 12.38). which of the following best describes the resulting solution?
