Calculate the change in the molar Gibbs energy of hydrogen gas when its pressure is increased isothermally from 1.0 atm to 100.0 atm at 298K.
calculate the amount of energy in kilojoules needed to change 153g of water ice at -10 C to steam at 125 C.
The citric acid cycle has a catabolic role, oxidizing acetate into CO2 and generating energy, and an anabolic role. Many of the citric acid cycle intermediates serve as precursors for the biosynthesis of larger molecules. Move each of the followin..
calculate the external pressure that must be applied to seawater, 1.14 M total ion concentration at 10 degrees celcius if the maximum concentration allowed in the product water is 166 mg/L
At 50 degree's Celsius the vapor pressure for methanol and ethanol are 406 and 222 torr, respectively. Given a mixture at 50 degree's Celsius that contains 0.2 mol of methanol and 0.1 mol of ethanol, compute the partial pressures of each liquid an..
the calculation supports the idea that thermal pollution around cooling vents of nuclear reactors is detrimental to marine life.
Important information about Proteins, A globular protein in aqueous surroundings contains the following amino acid residues; phenylamine, methionine, glutamate, lysine, and alanine.
The amount of lead in a aqueous sample is determined by atomic absorption spectrometry. Two standard solutions are prepared and used to make a calibration curve, and then the absorbance of the sample is measured.
A sample of nitrogen gas is contained in a piston with a freely moving cylinder. At 0 C, the volume of the gas is 307 mL. To what temperature must the gas be heated
An object made of aluminum has a mass of 8.37g. When it was placed in a graduated cylinder containing 20.0mL of water, the water level rose to 23.1mL. Calculate the density and specific gravity of the object.
