As an example, the equation for the reaction of hydrochloric acid with sodium can be denoted: This equation would be read as ""two HCl plus two Na yields two NaCl and H two."" But, for equations involving complex chemicals, rather than reading the letter and its subscript, the chemical formulas are read using IUPAC nomenclature. Using IUPAC nomenclature, this equation would be read as ""hydrochloric acid plus sodium yields sodium chloride and hydrogen gas."" This equation indicates that sodium"
"Nabalamprophyllite Nabalamprophyllite has a general formula of Ba(Na,Ba){NaTi[TiOSiO](OH,F)}. The name is given for its composition (Naba, meaning sodium, Na and barium, Ba) and relation to other lamprophyllite-group minerals. Lamprophyllite is a rare Ti-bearing silicate mineral usually found in intrusive igneous rocks. Nabalamprophyllite is monoclinic, which means crystallographically, it contains three axes of unequal length and the angles between two of the axes are 90°, and one is less than 90°. It belongs to the space group P2/m. The mineral also has an orthorhombic polytype (nabalamprophyllite-2O). This mineral belongs to the space group Pnmn. In terms of its optical properties, nabalamprophyllite"
