Metal hydroxides typically decompose to yield metal oxides and water through a process known as thermal decomposition. For example, when copper(II) hydroxide decomposes, it forms copper(II) oxide and water.
Metal oxides can be basic, acidic, or amphoteric depending on the metal and the oxidation state of the metal ion. Basic metal oxides react with acid to form a salt and water, while acidic metal oxides react with base to form a salt and water. Amphoteric metal oxides can act as both an acid and a base depending on the reaction conditions.
If the nitrates are of alkali metals, they decompose into Nitrites and Oxygen:NO3- --Δ--> NO2-+ O2If the nitrates are of other metals, they decompose into Metal oxides, Nitrogen dioxide and Oxygen:NO3- --Δ--> O2- + NO2 + O2
Metal oxides form alkalis when they dissolve in water. Non-metal oxides for acids. For example: carbon dioxide + water --> carbonic acid magnesium oxide + water --> magnesium hydroxide
Alkali metal hydroxides are strong bases that are highly water-soluble, forming alkaline solutions. Alkaline earth metal hydroxides are also bases but are less soluble in water compared to alkali metal hydroxides, resulting in less alkaline solutions.
Metal hydroxides typically decompose to yield metal oxides and water through a process known as thermal decomposition. For example, when copper(II) hydroxide decomposes, it forms copper(II) oxide and water.
Some metal oxides that decompose when heated include lead(II) oxide (PbO), mercury(I) oxide (Hg2O), and copper(II) oxide (CuO). When heated, these metal oxides break down into their respective metal and oxygen gas.
Metal oxides typically do not decompose when heated, but instead may undergo various chemical reactions such as reduction or oxidation. The specific behavior of a metal oxide when heated will depend on the type of metal and the conditions of heating.
Most metal oxides are basic in nature because they tend to react with water to form metal hydroxides, which are alkaline solutions. However, some metal oxides can exhibit acidic properties when dissolved in water, such as oxides of non-metals like sulfur.
Metal oxides typically form hydroxides when dissolved in water due to reaction with water molecules to produce hydroxide ions. These hydroxides can then further dissociate into metal cations and hydroxide ions in solution.
Metal oxides can be basic, acidic, or amphoteric depending on the metal and the oxidation state of the metal ion. Basic metal oxides react with acid to form a salt and water, while acidic metal oxides react with base to form a salt and water. Amphoteric metal oxides can act as both an acid and a base depending on the reaction conditions.

Most metal hydroxides and oxides e.g. K2O and KOH
Metal oxides can act as bases because of their ability to accept protons. When metal oxides react with water, they can form metal hydroxides, which are basic in nature due to their ability to release hydroxide ions in solution.
Oxides are the class of compounds formed when oxygen combines with elements. They typically consist of a metal or non-metal element bonded to oxygen. Oxides can vary widely in their properties and uses depending on the elements involved in the reaction.
Most metal oxides and hydroxides especially those of the alkali metals and alkaline earth metals.
