During a electrolysis experiment one silver electrode gained 0.0373 g, while the other silver electrode in the cell loses 0.0351 g. During the 5710 seconds it takes for this process to occur, the average current in the cell is 6.04 milliamps. What is the estimated value of the Faraday using the values for: a.) the electrode that gains silver? b.) the electrode that loses silver?
What is the difference between the virial equation of state and the SRK equation of state? When would you use one versus
A solution of ethanol (C2H5OH) in water is prepared by dissolving 73.2 mL of ethanol (density = 0.79 g/cm3) in enough water to make 250.0 mL of solution.
What is the theoretical yield (in g of precipitate) when 16.3 mL of a 0.586 M solution of barium hydroxide is combined with 18.7 mL of a 0.688 M solution of iron(III) nitrate

Alpha-linolenic acid is one of a large group of fatty acids that are found in fish oil, walnuts and canola seeds. These nutrients are essential for good health. All of these fatty acids consist of an unsaturated hydrocarbon that is terminated by a..
Which silver salt will precipitate first? Show calculations to support your answer. What is the concentration of Ag+ when the first precipitate begins to form?
When a 9.92-g sample of gaseous hydrogen bromide dissolves in 45.5 g of water in a coffee-cup calorimeter the temperature rises from 25.00 oC to 69.79 oC. Calculate H in kJ per mol of HBr for the solution process.
In a second experiment, a 1.217 g sample of a compound with the formula C6H14O(l) was burned in the same calorimeter. The temperature increased by 10.08 oC. Use these data, plus the information given below for CO2 and H2O, to estimate the standard..
