Substance-Related and Addictive Disorders In the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the revised chapter of âSubstance-Related and Addictive Disordersâ includes substantive changes to the disorders grouped there plus changes to the criteria of certain conditions.his new term and its loca-tion in the new manual reflect research findings that gambling disorder is similar to substance-related disorders in clinical expression, brain origin, comorbidity, physiology, and treatment.
Net Ionic Equation Definition. The net ionic equation is a chemical equation for a reaction which lists only those species participating in the reaction. The net ionic equation is commonly used in acid-base neutralization reactions, double displacement reactions, and redox reactions.
Net Ionic Equation Most reactions in an aqueous medium involve ions. However, when a reaction takes place two kinds of ions usually emerge: (1) spectator ions and (2) player ions. The names imply the character of the ions with respect to the reaction.he chemical equation for this reaction is written as: This equation contains all ions in the solution. However, sometimes its necessary to only include those ions that are players and leave out the spectators. A chemical equation that contains only the player ions is called the net ionic equation (nie).
