The streak test is done by scraping a specimen of the mineral across a piece of unglazed porcelain known as a "streak plate." Other rocks can be defined by relative abundances of key (essential) minerals; a granite is defined by proportions of quartz, alkali feldspar, and plagioclase feldspar. Ubiquitous means "found everywhere." Cleavage is described as excellent, good, poor, or absent, with the number of cleavage directions and the angles When in a rare crystallized form, this variety is especially aesthetic. Sulfur is a common element, with many uses. Galena most commonly forms cubic cleavage. The core is extremely hot (~3500 to more than 6000C). It is deposited from solution, often along with calcite and halite, as gangue in sulfide mineral deposits. The carbonate mineral that is most commonly encountered by geologists is calcite (CaCO 3). Rhombohedral cleavage, powdered form effervesces weakly in dilute HCl, curved crystal faces and frequent twinning Calcium carbonate reacts with sulfur dioxide and other gases in the combustion emissions, absorbs them, and prevents them from escaping to the atmosphere. Aqueous solutions of HI are known as hydroiodic acid or hydriodic acid, a strong acid.Hydrogen iodide and hydroiodic acid are, however, different in that the former is a gas under standard conditions, whereas the other is an aqueous solution of the gas.They are interconvertible. It is trimorphous with matraite and sphalerite.. Troilite has a chemical composition of FeS, while pyrrhotite's chemical composition is Fe (1-x) S.
