These terms are not guaranteed to refer to the same concept across time but are guaranteed to be consistent within a particular OWL export. Use 'cycAnnot:externalID' for unambiguously referring to a concept across OWL exports or across Cyc inference engines. the collection of samples of hydrazine; H2NNH2. hydrazine Hydrazine H2NNH2 Hydrazine http://en.wikipedia.org/wiki/Hydrazine the collection of samples of hydrazine; H2NNH2. hydrazine Hydrazine Pretty String (<a href="http://sw.opencyc.org/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> TERM STRING) means that STRING is the English word or expression (sequence of words) commonly used to refer to TERM. The predicate <a href="http://sw.opencyc.org/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> is used by the code which generates CycL to English paraphrases, but its applicability is not restricted to this use. prettyString WeakElectrolyte weak electrolyte The collection of all polyatomic chemical stuffs that partially decompose into ions when disolved in water. An instance of <a href="http://sw.opencyc.org/concept/Mx4rm5UkQPtBQdae9YygwAjewg" class="cyc_term">WeakElectrolyte</a> may be a mixture of chemical compounds.

Each instance of <a href="http://sw.opencyc.org/concept/Mx4r-BwMZoxtQdeYk5EgCqon5A" class="cyc_term">HazardousChemicalSubstanceType</a> is a collection of chemical substances whose instances are hazardous to humans. These materials require certain precautions when being handled to lower the risk of exposure or in the case of explosive materials, lower the risk of combustion. Note: each instance of this collection must be an instance of <a href="http://sw.opencyc.org/concept/Mx4rvVjNlZwpEbGdrcN5Y29ycA" class="cyc_term">ChemicalSubstanceType</a>. base ChemicallyBasicSubstance The collection of all chemically basic substances. An <a href="http://sw.opencyc.org/concept/Mx4rvVny6pwpEbGdrcN5Y29ycA" class="cyc_term">ExistingStuffType</a>. The collection of all weak base types. The instances of the instances of this collection have a moderate tendency to abstract hydronium ions from water to form OH- ions. weak base BaseType-Weak wikipediaArticleName (<a href="http://sw.opencyc.org/concept/Mx4rTv-jk9SPTXa991kk5mAvHg" class="cyc_term">wikipediaArticleName</a> THING NAME) means that in <a href="http://sw.opencyc.org/concept/Mx4rtqXA6OC8QdiWC72DuLJdUw" class="cyc_term">Wikipedia_WebSite</a> THING is described by an article with the title NAME Wikipedia Article Name Wikipedia Article URL (<a href="http://sw.opencyc.org/concept/Mx4rNv0nbm4TTjOp7yhmnzOyqg" class="cyc_term">wikipediaArticleURL</a> THING URL) means that in <a href="http://sw.opencyc.org/concept/Mx4rtqXA6OC8QdiWC72DuLJdUw" class="cyc_term">Wikipedia_WebSite</a> THING is described by an article located at URL wikipediaArticleURL the collection of samples of hydrazine; H2NNH2. hydrazine Hydrazine An instance of <a href="http://sw.opencyc.org/concept/Mx4rHQdVmB_TEdaAAABQ2rksLw" class="cyc_term">SecondOrderCollection</a> and a specialization of <a href="http://sw.opencyc.org/concept/Mx4rvVjNlZwpEbGdrcN5Y29ycA" class="cyc_term">ChemicalSubstanceType</a>. Each instance of <a href="http://sw.opencyc.org/concept/Mx4r4eCNdPNRQdaMr9_eOeadhA" class="cyc_term">BaseType_Bronsted_Lowry</a> is a type of substance whose instances are proton acceptors. BaseType-Bronsted-Lowry Broensted-Lowry base chemical compound ChemicalCompoundTypeByChemicalSpecies A collection of collections and a specialization of <a href="http://sw.opencyc.org/concept/Mx4rvVjNlZwpEbGdrcN5Y29ycA" class="cyc_term">ChemicalSubstanceType</a>. Each instance of <a href="http://sw.opencyc.org/concept/Mx4rvUCoPtoTQdaZVdw2OtjsAg" class="cyc_term">ChemicalCompoundTypeByChemicalSpecies</a> is a specialization of <a href="http://sw.opencyc.org/concept/Mx4rvVj27ZwpEbGdrcN5Y29ycA" class="cyc_term">PartiallyTangible</a> whose instances are defined _only_ by their chemical composition -- not by their physical state or any other property. Instances of <a href="http://sw.opencyc.org/concept/Mx4rvUCoPtoTQdaZVdw2OtjsAg" class="cyc_term">ChemicalCompoundTypeByChemicalSpecies</a> are collections whose instances are completely uniform with each other in terms of chemical structure, e.g., <a href="http://sw.opencyc.org/concept/Mx4rvVjAHZwpEbGdrcN5Y29ycA" class="cyc_term">Water</a>, <a href="http://sw.opencyc.org/concept/Mx4rvVkLW5wpEbGdrcN5Y29ycA" class="cyc_term">Caffeine</a>, and <a href="http://sw.opencyc.org/concept/Mx4rvVj8YZwpEbGdrcN5Y29ycA" class="cyc_term">IronOxide</a>. This collection does not include the chemical elements -- such as <a href="http://sw.opencyc.org/concept/Mx4rvVjIQpwpEbGdrcN5Y29ycA" class="cyc_term">Carbon</a> and <a href="http://sw.opencyc.org/concept/Mx4rvVjIyJwpEbGdrcN5Y29ycA" class="cyc_term">Oxygen</a>, since there can be multiple types that molecules can be formed out of a single element, e.g. O2 and <a href="http://sw.opencyc.org/concept/Mx4rwQCj4pwpEbGdrcN5Y29ycA" class="cyc_term">Ozone</a>. Use the broader collection, <a href="http://sw.opencyc.org/concept/Mx4rvVjNlZwpEbGdrcN5Y29ycA" class="cyc_term">ChemicalSubstanceType</a>, for substances which have a general chemical specification, that is, whose instances do not have exactly the same chemical composition but fall within certain specifications, e.g., <a href="http://sw.opencyc.org/concept/Mx4rvWXHLJwpEbGdrcN5Y29ycA" class="cyc_term">DNAStuff</a>. the collection of samples of hydrazine; H2NNH2. hydrazine Hydrazine A specialization of <a href="http://sw.opencyc.org/concept/Mx4rvVkF6pwpEbGdrcN5Y29ycA" class="cyc_term">InanimateObject</a>. Each instance of <a href="http://sw.opencyc.org/concept/Mx4rvVkKBZwpEbGdrcN5Y29ycA" class="cyc_term">InorganicMaterial</a> is a tangible thing wholly composed of one or more types of inorganic molecule. Instances of <a href="http://sw.opencyc.org/concept/Mx4rvVkKBZwpEbGdrcN5Y29ycA" class="cyc_term">InorganicMaterial</a> usually didn't originate as parts or products of living things. Notable specializations of <a href="http://sw.opencyc.org/concept/Mx4rvVkKBZwpEbGdrcN5Y29ycA" class="cyc_term">InorganicMaterial</a> include <a href="http://sw.opencyc.org/concept/Mx4rwQCJAJwpEbGdrcN5Y29ycA" class="cyc_term">Mineral</a>, <a href="http://sw.opencyc.org/concept/Mx4rvVisOZwpEbGdrcN5Y29ycA" class="cyc_term">Metal</a>, and <a href="http://sw.opencyc.org/concept/Mx4rvViG-5wpEbGdrcN5Y29ycA" class="cyc_term">Glass</a>.
