1. Thermal decomposition equation of aluminum hydroxide

1. Thermal decomposition of aluminum hydroxide into aluminum oxide and water. The chemical equation of the reaction is: 2Al(OH) 3Δ=Al2O3+3H2O.

2. Chemistry is a type of natural science that studies the composition, properties, structure and change laws of substances at the molecular and atomic levels; it is a science that creates new substances. The world is composed of matter, and chemistry is one of the main methods and means used by humans to understand and transform the material world. It is a discipline with a long history and full of vitality. Its achievements are an important symbol of social civilization. There are There are two forms of change: chemical change and physical change

2. Is the thermal decomposition of aluminum hydroxide endothermic or exothermic

The thermal decomposition of aluminum hydroxide is an endothermic reaction.

When aluminum hydroxide is heated to about 220°C, it begins to decompose endothermically and release bound water. This endothermic dehydration process delays the burning of the polymer and slows down the burning rate. It is precisely because aluminum hydroxide absorbs a lot of heat when it decomposes and only releases water vapor when it is thermally decomposed without producing toxic, flammable or corrosive gases, that aluminum hydroxide has become an important inorganic flame retardant filler.

Ps: Endothermic reactions are chemical reactions that absorb heat during the reaction. In an endothermic reaction, the heat absorbed by breaking the chemical bond is greater than the energy released by the carboxyl forming the chemical bond.

Note: Not all chemical reactions that require heating are endothermic reactions.
