There are over fifteen isotopic forms of sulture. one of those isotopes is sulfur-29 (amu=28.99) What is the binding energy for one mole of sulfure-29, given the masses of a proton, a neutron, and an electron are 1.007276u, 1.008666u, .000548u
The reaction for the decomposition of dinitrogen pentoxide to form nitrogen dioxide and oxygen gas has the rate constant 1.7 x 10-3 s-1. This is a first order reaction.
What was the percentage by mass of Mg(OH)2 in the original sample? [Hint: When Mg(OH)2 or Al(OH)3 reacts with HCl(aq), the products are a chloride salt, water and CO2(g). Assume that all of the CO2(g) leaves the solution without reacting.]
How much heat is required to raise the temperature of a mole of oxygen from 298 to 3000 K at constant pressure
What are the possible values for the principal quantum number (n), the azimuthal quantum number (l) and the magnetic quantum number
What is the energy released when 0.711 g are converted to energy? Express your answer in joules. For self-consistent units you must use kg because 1 J = 1 kg m2/s2.
The heat of solution of ammonium chloride is 15.2 kJ/mol. If a 6.134 g sample of NH4Cl is added to 65.0 mL of water in a calorimeter at 24.5°C, what is the minimum temperature reached by the solution?
72 ml of a 1.70 m solution is diluted to a volume of 288 ml.a 144 ml portion of that solution is diluted using 149 ml
How would the addition of sodium chloride affect the hydrated cobalt(II) ion equilibrium? Explain using Le Chatelier's principle
If 18.08 grams of ammonia (NH3) react, how many grams of water should theoretically be produced?
A 4.50-g sample of LIL at 25.oC dissolves in 25.0 mL of water also at 25.0C. The final equilibrium temperature of the resulting solution is 60.8C. What is the enthalp of solution of LICL expressed in kilojoules per mole?
In 1978, scientists extracted a compound with antitumor and antivirus properties from marine animals in the Caribbean Sea. A sample of the compound didemnin-A
compare the stabilities of each of the four conjugate bases that would be formed from the doprotonation of the four different OH groups and determine which of hte OH is most acidic.
