Determine the binding energy of an O-16 nucleus. The O-16 nucleus has a mass of 15.9905 amu. A proton has a mass of 1.00728 amu, a neutron has a mass of 1.008665 amu, and 1 amu is equivalent to 931 MeV of energy.
One way to measure ionization energies is ultraviolet photoelectron spectroscopy (UPS, or just PES), a technique based on the photoelectric effect. In PES, monochromatic light is directed onto a sample, causing electrons to be emitted.
boiling water at sea level is hotter than boiling water in the mountains. Water used to sterilize surgical equipment is heated to 120 degrees C at 2.0 atm in an autoclave.
To do so she places 100.0g of water at 58.60C into the calorimeter which already contains 100.0g of water at 19.30C. The final temperature of the water in the calorimeter is 38.70C. What is the heat capacity of the calorimeter
the equilibrium would shift to the right producing more products the equilibrium would shift to the left producing more reagents the equilbrium would not be effected by the created pressure change the equilibrium would speed up the equilibrium wou..
Carbon monoxide gas burns in oxygen to form carbon dioxide gas. Write a balanced equation for the reaction and determine the volume of oxygen needed to react completely with 561 mL of CO at 40.0°C and 1.00 atm.
The vapor pressure of ethyl ether is 7.87 in. Hg at 2°C; 11.8 in. Hg at 12°C; 27.5 in. Hg at 32°C; 29.9 in. Hg at 35°C; 39.3 in. Hg at 42°C. What is the normal boiling point of ethyl ether

NaOH and then 25.0mL of 0.5 M of your weak acid HA with 0.500M NaOH. How would the titration curves compare at 10 or 15 mL of NaOF beyond the equivalence points
Will the boiling point of a solution of 10 g of NaCl (which has no appreciable vapor pressure at 100 oC) in 100 mL of water be higher than, lower than
The sodium emission intensity from the diluted sample is 0.092. The calibration curve for sodium is INa = 0.083 L.mg-1 [Na] + 0.001. What is the concentration of Na in the diluted carrot solution? What is the concentration of Na in the concentrate..
The reaction for the decomposition of dinitrogen monoxide gas to form an oxygen radical is: N2O--->N2 + O2. If the activation energy is 250 kj/mol and the frequency factor is 8.0 x 10^11 s^-1, what is the rate constant for the first order reaction..
