What is the Kp equalibrium constant expression for the following equalibrium? S8 (s) + 24F2(g)<--> 8SF6(g) Kp=
A laser pulse with a wavelength of 532 nm contains 3.85 mJ (milliJoule) of energy. (a) Calculate the frequency and energy per photon of the laser light. (b) How many photons are in the laser pulse? (c) What is the energy in kilojoules per mole (kJ..
Specify whether a simple distillation or a fractional distillation would be more suitable for each of the following purifications, and briefly justify your choice.
What mass of silver chloride can be produced from 1.70 L of a 0.177M solution of silver nitrate.
at 350 degrees celcius and 200 atm the % yield is 50%. Calculate how many grams of N gas are required to produce 25.000g Ammonia
Solid CO2 (dry ice) sublimes at 195 K and its heat of sublimation ?Hsubl = 25.2 kJ/mol. A block of dry ice with a mass of 32.1 g sublimes. What is the entropy change, ?S, of the CO2? (Enter your answer in J/K).

Suppose a piece of silver jewelry contains 6.53×1022 atoms of silver (Ag). How many dozens of silver atoms are in the piece of jewelry. Express your answer numerically in dozens.
A ground state hydrogen atom absorbs a photon of light having a wavelength of 92.30 nm. It then gives off a photon having a wavelength of 1820 nm
Develop a scheme to separate Ag+, Mg2+, and Pb2+ cations in solution and draw a flow chart that depicts your scheme.
a rectangular block of plastic, measuring 1.50 cm by 2.29 cm by 1.84 cm, floats in the middle of the Pacific Ocean. The volume of sea water displaced by the plastic block is 5.46 cm3. Assuming the density of the sea water is 1.025 g/mL, what is th..
HNO3 has 2 dissociating ions whereas Al(NO3)3 has 4, which should result in a higher conductance value. Would this have something to do with aluminum nitrate being paired with water as a solid?
