  3. Molar ionization energies of the elements - Wikipedia

    en.wikipedia.org/wiki/Molar_ionization_energies...

    These tables list values of molar ionization energies, measured in kJ⋅mol −1. This is the energy per mole necessary to remove electrons from gaseous atoms or atomic ions. The first molar ionization energy applies to the neutral atoms.

    The contribution of the muscle to the specific heat of the body is approximately 47%, and the contribution of the fat and skin is approximately 24%. The specific heat of tissues range from ~0.7 kJ · kg−1 · °C−1 for tooth (enamel) to 4.2 kJ · kg−1 · °C−1 for eye (sclera). [13]

    For each atom, the column marked 1 is the first ionization energy to ionize the neutral atom, the column marked 2 is the second ionization energy to remove a second electron from the +1 ion, the column marked 3 is the third ionization energy to remove a third electron from the +2 ion, and so on.

  7. Joule per mole - Wikipedia

    en.wikipedia.org/wiki/Joule_per_mole

    Since there are 6.02214076 × 10 23 particles (atoms, molecules, ions etc.) per mole, 1 joule per mole is equal to 1 joule multiplied by 6.02214076 × 10 23 particles. Because of the typical order of magnitude for energy changes in chemical processes, kJ·mol −1 is normally used instead of J·mol −1 .

    In 1970, South Africa produced 995 tonnes or 32 million ounces of gold, two-thirds of the world's production of 47.5 million ounces. [2] Production figures are for primary mine production. In the US, for example, for the year 2011, secondary sources (new and old scrap) exceeded primary production. [3]
