show that the energy eigenvaules for the free particle E=h2k2/2m are consistent with the classical result E=1/2mv2
Suppose we are dealing with calcium chloride as opposed to the chemical in the video. If a solution contains 70 g of calcium chloride per 100 g of water at 25 degrees Celsius
The pressure on 200 ml of oxygen gas changes from 380 mm hg to 760 mm hg. The temperature does not change. What is the new volume of the oxygen gas?
What mass of carbon dioxide is present in 1.00 cm^3 of dry air at a temperature of 15 0C and a pressure of 697 torr?
Chemistry Concentrations, In each of the following pairs, indicate which has the higher concentration of Cl- ion
A supersaturated solution of potassium nitrate is formed by adding 150 g KNO3 to 100 g water, heating until the solute completely dissolves is agitated, how much potassium nitrate will perciapitate.
Calculate the heat released when 3.25 L of Cl2(g) with a density of 1.88 g/L reacts with an excess of sodium metal at 25°C and 1 atm to form sodium chloride.
What is the mole fraction of water in this solution? What is the vapor pressure of the solution at 25 degrees Celsius, given the vapor pressure of pure water at 25 degrees Celsius is 23.8torr
The Haber process is used in industry to produce ammonia from N2 and H2. A reactor contains NH3, N2, and H2 at equilibrium at 1000 K. The concentration of NH3 is 0.102 moles/liter, N2 is 1.03 moles/liter, and H2 is 1.62 moles/liter. Calculate the ..
Can complex compounds like dioxin and furan actually be thermally oxidized and destroyed?? At what temperature would these compounds actually be destroyed.
an 8 g sample of a copper ore was dissolved in an acid solution and then reacted with NO3- from a KNO3 salt solution. it required 71.5 ml of a .155 M KNO3 solution to fully react the copper in the ore sample.
Calculate the change in entropy (in J/K) for the following reaction at 298 K: C(s) + H2O(g) ? CO(g) + H2(g) Use entropy for graphite (diamond is too expensive).
