The atomic radius of nickel is 124 pm and the average atomic mass of nickel is 58.6934 amu. Calculate the density of nickel assuming a simple cubic, body-centered cubic, and face-centered cubic unit cell structures. Now, the experimental density of nickel under normal conditions of temperature and pressure is 8.908 cm^-3. Predict its crystal structure, and use the experimental density to obtain an experimentally-corrected atomic radius.
Calculate the resulting discharge temperature and the required horsepower for one stage compression of the following gas properties. Construct a plot of such discharge temperature and required horsepower versus one stage compression ratios of 2, 3..
in the preparation of the esters given in this reaction the reaction product is extracted with 5 sodium bicarbonate
What happens to the interference pattern that results from the diffraction of electrons passing through two closely spaced slits if the rate of electrons going through the slits is decreased to one electron per hour
Calculate the value of Ksp at this temperature. Give your answer in scientific notation
The vapor pressure of water at 30.0 degree celsius is 31.82mmHg. A portion of mannitol (C6H14O6, non-volatile) is added to make a 3.50M solution. The solution has a density of 1.048 g/mL. What is the new vapor pressure of the solution
In the electrolysis of water, 2h20 yields 2h2 plus o2, if the volume of oxygen produced was 8ml, what would be the volume of hydrogen produced?
Silver has only two naturally occurring isotopes 107ag with a mass of 106.90509 amu and an abundance of 51.84% and 109 ag with a mass of 108.9047 amu. calculate the atomic mass of silver.
Five kg of water initially a saturated vapor at 100kPa are cooled to saturated liquid while the pressure is maintained constant. Sketch the process on a p-v diagram
How much heat (in kJ) is evolved in converting 1.00 mole of steam at 145 C to ice at 0 C)? (The heat capacity of ice is 2.09 J/g C and the heat of vaporization of water is 32.9 kJ/mol)
We most often express heat as kilocalories and kilojoules rather then calories and joules. When 1 pound of fat is burned in the body,9.4 kilocalories of energy is produced. Express that as a) calories b)kilojoules
