41. Most polymorphs of organic molecules only differ by a few kJ / mol in lattice energy. 42. The rate of dissolution may also be altered by choosing a suitable polymorph of a compound. 43. As they travel through the cargo decks, Rimmer falsely alerts the others to the Polymorph . 44. The polymorphs evolved from these organisms. 45. Olivine, wadsleyite, and ringwoodite are polymorphs found in the upper mantle of the earth. 46. Because they are even more basic, the alkali-loaded polymorphs are correspondingly more reactive. 47. Brainoil entered Polymorph Studios in March 2002 to record their debut LP with engineer Dan Rathbun. 48. Two polymorphs are known, one orthorhombic ( shown in the infobox ) and one monoclinic. 49. Botallackite is the least stable of the four Cu 2 ( OH ) 3 Cl polymorphs . 50. The silica polymorph that is most stable at the Earth's surface is ?-quartz.
