Key Points

  • The mole fraction yi is constant when the amount of each substance is constant, so we have Œ@ ln.yip=pı/=@pT;fnig D 1=p.
  • Stoichiometry (/ˌstɔɪkiˈɒmɪtri/ ⓘ) is the relationships between the quantities of reactants and products before, during and after chemical reactions.
  • The nomenclature used most frequently worldwide is the one created and developed by the International Union of Pure and Applied Chemistry (IUPAC).
  • The chemical potential of a cation, its activity, and the electric potential of the phase are related by Eq. 10.1.9 on page 289: C D ı C C RT ln aC C zCF .
  • For example, in the mineral hematite (Fe2O3), the cation is Fe3+ (iron) and the anion is O2−(oxygen).
  • Carbonate reefs and carbonate sediments form in tropical regions where there is little input of clastic sediments.
