A generic salt, AB, has a molar mass of 189 g/mol and a solubility of 6.10 g/L at 25 C what is the Ksp of this salt
Ammonium Carbonate, NH4CO2, decomposes as follows: NH4CO2NH2(s) -> 2NH3(g) + CO2(g) Starting with only the solid, it is found that at 40C the total gas pressure is .363 atm. Calculate Kp.
solution with a pipet to a second 500.0 mL volumetric flask and diluting to the mark. Find the concentration of Ag+ in the dilute solution.
As mentioned in the text, Ni3Al is used in the turbines of aircraft engines because of its strength and low density. Nickel metal has a cubic close-packed structure with a face-centered cubic unit cell
The greater volume per mole at the higher temperature indicates greater average intermolecular distances and hence weaker intermolecular forces.
