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.
