A famous foot race in California starts from the bottom of Death Valley (100 m below sea level) and finishes at the top of Mt. Whitney (4300 m above sea level). This race is a challenge to the human organism! By what percentage does the oxygen number density decrease between the start and the finish of the race?
suppose you wanted to dissolve 106 g of Na2CO3 in enough H2O to make 6.00L of solution what is the molar mass of Na2CO3.
Organic Chemistry Lab: Reduction and Spectroscopy, 1. Sketch the NMR spectrum you would expect to observe for the following compounds:
Explain would the calculated molarity of NaOH be too high or too low If the KHP weighed in your experiment today was contaminated with some unknown inert substance.
Draw a structure consistent with the following set of data: a hydrocarbon with a molecular ion at m/z = 68 and an IR absorptions at 3310
Acid catalyzed hydration of 2-pentene giives two alcohols, each with the molecular formula C5H12O. a) Draw the structure of 2-pentene.
a 100.-L flask contains a mixture of methane, CH4, and argon at 25°C. The mass of argon present is 228 g and the mole fraction of methane in the mixture is 0.650. calculate the total kinetic energy of the gaseous mixture.
Electrochemistry and Solubility, The potential of the cell Bi|Bi2S3(s) |Bi2S3(aq)|Bi is 0.96 V at 25*C. Calculate the solubility of Bi2S3, Assume it is an ideal solution.
A 25.0-mL solution of 0.0430 M EDTA was added to a 48.0-mL sample containing an unknown concentration of V3 . All V3 present formed a complex, leaving excess EDTA in solution. This solution was back-titrated with a 0.0440 M Ga3 solution until all ..
