Determine the pH of an HF solution of each of the following concentrations: a) 4.60 x 10^-2 b) 2.30 x 10^-2
Ammonium carbamate can dissociate into gases at 25 C according to the reaction: NH2COONH4(s) 2NH3(g) + CO2(g) If sufficient ammonium carbamate is sealed in a flask, the total pressure will be 0.117 atm at equilibrium. What is the value of Kp at ..
Liquid nitrogen has a density of 0.807 g/mL at -195.8 °C. If 1.00 L of N2(l) is allowed to warm to 25°C at a pressure of 1.0 atm, what volume will the gas occupy.
discuss the various ways that the Fischer esterification reaction can be run to maximize conversion to ester.
When performing extractions it is often better to do multiple extractions rather than one large volume extraction. suppose you have 100mg of a sample dissolved in 0.6ml of water.
Gallium has two common isotopes Ga-69 and Ga-71. Suppose we wanted to use the Ga-71 isotope for some reason, and obtained a pure 6.0g sample of Ga-71.
temperature of 20.0 K and a pressure of 101.3 kPa. What will be the volume when the temperature is changed to 40.0 K and the pressure is changed to 50.65 kPa?
How many grams of ammonium sulfate should be dissolved in 160 ml of water for the preparation
Classify each reactant as the reducing agent, oxidizing agent, or neither.
The crystalline form of silver (Ag) is composed of face-centered cubic unit cells. If the density of silver is 10.48 g/cm3 at room temperature
explain in detail, using thermodynamics principles, why the mixing of pure chemicals to form homogeneous mixture is a so-called spontaneous process
At its boiling point, the vaporization of 0.579 mol CH4 requires 4.76 kJ of heat. What is the enthalpy of vaporizating of methane?
In an oversight in the experiment Jamie did not add the 4-5 additional drops of 6M HNO3. As a result, will the reported number of moles of oxygen be too high or too low in the final product. Explain.
