Central sleep apnea is a breathing disorder that occurs during sleep and results when the brain fails to activate the respiratory muscles. This leads to a brief pause in breathing that may last 10 seconds or longer. Unlike the more standard obstructive sleep apnea - which is caused when the upper airway becomes temporarily obstructed - in central sleep apnea, the effort to breathe stops and there is no clear obstruction of the airway. Though the cause is slightly different, the outcome of central sleep apnea is the same.
Naming Inorganic Compounds. Binary Molecular Compounds. When a pair of elements form more than one type of covalent compound, Greek prefixes are used to indicate how many of each element are in a compound. The more electronegative element is written last and its ending is changed to ide.Examples.hen a pair of elements form more than one type of covalent compound, Greek prefixes are used to indicate how many of each element are in a compound.
Post. Share. Molecular compounds or covalent compounds are those in which the elements share electrons via covalent bonds. The only type of molecular compound a chemistry student is expected to be able to name is a binary covalent compound.This is a covalent compound made up of only two different elements.Here is a look at the nomenclature rules for molecular compounds, plus some examples of how to name the compounds. Molecular compounds contain two or more nonmetals (not the ammonium ion).his is a covalent compound made up of only two different elements.
