  2. 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.

  3. Joule per mole - Wikipedia

    en.wikipedia.org/wiki/Joule_per_mole

    [1] [2] For example, the Gibbs free energy of a compound in the area of thermochemistry is often quantified in units of kilojoules per mole (symbol: kJ·mol −1 or kJ/mol), with 1 kilojoule = 1000 joules. [3] Physical quantities measured in J·mol −1 usually describe quantities of energy transferred during phase transformations or chemical ...

  4. List of most-downloaded Google Play applications - Wikipedia

    en.wikipedia.org/wiki/List_of_most-downloaded...

    The 500-million download threshold for free applications has been established to maintain the list's manageability and focus on the most widely distributed apps. It's worth noting that many of the applications in this list are distributed pre-installed on top-selling Android devices [ 2 ] and may be considered bloatware by some people because ...

  5. List of open-source software for mathematics - Wikipedia

    en.wikipedia.org/wiki/List_of_open-source...

    The primary difference between a computer algebra system and a traditional calculator is the ability to deal with equations symbolically rather than numerically. The precise uses and capabilities of these systems differ greatly from one system to another, yet their purpose remains the same: manipulation of symbolic equations.

  6. Ionization energies of the elements (data page) - Wikipedia

    en.wikipedia.org/wiki/Ionization_energies_of_the...

    The first of these quantities is used in atomic physics, the second in chemistry, but both refer to the same basic property of the element. To convert from "value of ionization energy" to the corresponding "value of molar ionization energy", the conversion is: 1 eV = 96.48534 kJ/mol 1 kJ/mol = 0.0103642688 eV [12]

  7. List of Android app stores - Wikipedia

    en.wikipedia.org/wiki/List_of_Android_app_stores

    This form of the app store is often used by web developers to distribute apps that are not allowed in the Google Play Store; this may be due to an app allowing users wider access to the app system, or offering apps for "niche users" who choose to use only free and open-source software (F-Droid) or prefer to play indie games (Itch.io). Moreover ...

  8. List of quantum chemistry and solid-state physics software

    en.wikipedia.org/wiki/List_of_quantum_chemistry...

    Quantum chemistry computer programs are used in computational chemistry to implement the methods of quantum chemistry. Most include the Hartree–Fock (HF) and some post-Hartree–Fock methods. They may also include density functional theory (DFT), molecular mechanics or semi-empirical quantum chemistry methods .

  9. Orders of magnitude (energy) - Wikipedia
