The main types of explosions that may occur after the combination of chemicals include the following： 1. **Physical explosion**： -Caused by a sharp increase in pressure, it is common in the rapid expansion of gas in a closed container. 2. **Chemical explosion**： -**Decomposition explosion**: Certain unstable compounds (such as peroxides) decompose and release large amounts of gas and heat when heated or hit. -**Redox reaction**: Such as a mixture of potassium chlorate and sugar, the oxidizing agent reacts with the reducing agent to release a lot of energy. -**Compound reaction**: For example, hydrogen and chlorine react under light to produce hydrogen chloride with explosion. -**Polymerization reaction**: Some monomers (such as ethylene) polymerize violently under certain conditions, releasing heat and causing explosions. 3. **Nuclear explosion**： -It involves nuclear fission or fusion, usually related to radioactive substances, and is not within the scope of conventional chemical reactions. Examples of common combinations： -**Ammonium nitrate and fuel oil** (ANFO): A redox reaction commonly used in industrial blasting. -**Sodium azide (NaNo)**: Decomposing explosive material in automobile airbags. -**Nitroglycerin**: Highly sensitive decomposition of explosives. Safety tips： -**If professional needs are not involved, please do not try to mix chemicals**, many reactions are extremely dangerous or even fatal. -When operating chemicals, safety regulations must be strictly observed, protective equipment must be worn, and carried out under the guidance of professionals. If you have any further questions, it is recommended to consult an expert in the field of chemical or blasting engineering.
