No, it can explode with or without oxygen
Because: an explosion doesn't have to be a chemical change.
Explosions are a common phenomenon in people's daily lives. It is generally believed that the phenomenon of rapid change of matter and the release of a large amount of energy to do mechanical work on the surrounding medium, which may be accompanied by sound, light and heat effects, is called explosion. The basic characteristics of explosion are high speed, power and strong destructive effect.
According to the causes of explosions, various explosion phenomena in nature can be summarized into three categories: physical explosions, chemical explosions and nuclear explosions.
The characteristics of physical explosion are that the explosion process is a physical process, that is, the chemical composition of the substance before and after the explosion does not change, but the state of matter changes. For example, when the pressure in the steam boiler is too high, exceeding the compressive strength that the boiler can withstand, causing the boiler to suddenly rupture and make a loud noise, it is a typical physical explosion.
The characteristics of chemical explosion are: the explosion process is a sharp chemical reaction process, releasing enough heat energy, forming high temperature and high pressure gas, and working on the external expansion. The chemical composition and properties of the substance after the explosion are different from those of the substance before the explosion, such as the formation of water vapor, oxygen and nitrogen after the explosion of ammonium nitrate explosives. Both gas explosions and explosives explosions are chemical explosions.
Nuclear explosion is a chain reaction of nuclear fission (fission of U235) or nuclear fusion (fusion of deuterium, tritium, lithium) of the atoms of certain substances, which instantly releases huge energy, causing the fission or fusion products to form high-temperature and high-pressure gas and rapidly expand and work, causing huge destructive effects. The energy released during the nuclear explosion process can reach millions of times the explosion energy of ordinary explosives, and has a strong blasting effect.
Questions about oxygen:
Explosions caused by the combustion of substances reacting with oxygen belong to the category of chemical explosions.
But at the same time, it should be emphasized that the explosion caused by combustion does not necessarily require oxygen. For example, hydrogen can burn in chlorine, and of course the mixture of chlorine and hydrogen can also explode.
There is about combustion, which can be supplemented if needed.
