Identify three markets in the U. S. economy that are oligopolistic in nature. Whats the nature of the interdependence observed in those markets and provide an example of the strategic behavior involved.
Take photographs of your experiment set up and your results. Did either of the mouth rinses contain fluoride? How did you know?
Problem- If 79.0mL of 0.127 mol/L NaOH(aq) and 50.0mL of 0.189 mol/L HA(aq) are mixed, then what is [HA] at equilibrium? Assume that HA is a weak monoprotic acid with pKa=5.55 at 25oC.
If you are trying to recognize the molar mass of an unknown gas as well as your measurements is: atmospheric pressure = 1.05 atm, temperature = 25.0oC, volume = 0.167 L and the mass of gas collected = 0.357 grams. Define what is the molar mass of ..
The standard free energy change for a chemical reaction is +21.9kJ/mole. what is the equilibrium constant for the reaction at 87 degrees?(R=8.314J/K mole.
why is it an important concept that atoms generally appear in whole number molar ratios to each other in chemical
Presume that we have a mixture of N2 (g) and O2 (g) of unknown composition whose total pressure is 385torr. If all the oxygen as is removed from the mixture by reaction with phosphorus, which doesn't react directly with nitrogen then the new press..
To a 100 mL volumetric flask are added 1.00 mL volumes of three solutions: 0.0100 M AgNO3, 0.220 M NaBr, and 0.100 M NaCN. The mixture is diluted with deionized water to the mark and shaken vigorously.
The alcohol content of hard liquor is normally given in terms of the "proof," which is defined as twice the percentage by volume of ethanol (C2H5OH) present. Calculate the number of grams of alcohol present in 1.00 L of 81-proof gin. The density o..
Draw a representation for TPCP that would represent its structure if the phenyls were perpendicular to the 5-membered ring (a "paddle-wheel" structure) and a representation that represents the "propeller" structure shown by the computer.
Plot the results to obtain a protein denaturation profile and calculate the transition mid-point of unfolding. What is the significance of the transition curve? What does the mid-point signify? What protein folding process does the data imply?
In a Diels-Alder reaction between 1mL (12mmol) of cyclopentadiene and 1.393 g (12mmol) of maleic acid, How do you calculate the Theoretical Yield
A 1.996 gram sample of unknown monoprotic acid is dissolved in some water. This acid solution is then titrated to the end point with 27.38 mL of a solution of 0.4165 M KOH.
