Write a balanced net ionic equation for the reaction of each of the following hydrides with water: (b) NH3.

A net ionic equation represents the chemical species that are involved in a reaction, excluding spectator ions. It focuses on the actual chemical change occurring in the solution, highlighting the ions and molecules that participate directly in the reaction. This simplification helps in understanding the essential components of the reaction and is particularly useful in aqueous solutions.

Ammonia (NH3) is a weak base that can accept protons (H+) from water, leading to the formation of ammonium ions (NH4+) and hydroxide ions (OH-). This property is crucial in understanding its reaction with water, as it illustrates the acid-base behavior of ammonia in aqueous solutions. The equilibrium established in this reaction is fundamental to many biological and chemical processes.

Hydrides, such as ammonia, react with water to produce hydroxide ions and other products depending on the hydride's nature. In the case of ammonia, the reaction with water results in the formation of ammonium and hydroxide ions, which is essential for understanding the basicity of ammonia. This concept is important for predicting the outcomes of reactions involving hydrides in aqueous environments.
