Any fire or explosive need oxygen to burn but with explosives the oxygen is in the molecule and it reacts with itself. Fuels need external oxygen to cause a explosion. The chemical reaction varies depending on what compound were used to prepare the explosive normally a nitrate (NO, providing the oxygen) and carbon (C, as the fuel).
The shape of the charge has nothing to do with the chemical reaction. The reaction depends on the explosive material used.
The energy released when dynamite explodes comes from the chemical reaction within the dynamite itself. The explosive compound in dynamite, such as nitroglycerin, rapidly decomposes and releases a large amount of heat, pressure, and gas, resulting in the explosion.
A chemical explosion is a very quickly chemical reaction.
It explodes cause of a chemical reaction.
The mixture of oxygen and hydrogen at high temperature (a reaction occur) is very explosive.
Although the firecracker gets its energy from a chemical reaction, most of the damage it does is physical from the shockwave coming from it as it explodes. Very near the explosion there will also be some chemical damage as the burning explosive can burn some its surroundings - and burns are a type of chemical damage.
The energy conversion that occurs when a stick of dynamite explodes is chemical energy being converted into thermal, mechanical, and sound energy. The explosive material in the dynamite undergoes a rapid chemical reaction, releasing large amounts of heat, pressure, and sound waves in the process.
Usually a reaction must produce some sort of gas to be explosive.
It explodes like a volcano! It explodes like a volcano!
because a chemical reaction happens to make it explode
When TNT (trinitrotoluene) explodes, a rapid chemical reaction occurs, converting the solid explosive into hot gases and producing a significant amount of heat and pressure. This reaction happens at a speed of about 6,900 meters per second, creating a shock wave that can cause destruction to nearby structures and objects. The explosion generates a loud noise and a distinct shockwave, which can be felt over considerable distances. The energy released causes fragmentation and can propel debris at high speeds, making it a powerful explosive material.
Evidence of chemical changes in a firecracker that explodes includes the release of gases, formation of new compounds like carbon dioxide and water vapor, and a change in color or odor. Additionally, the heat and light produced during the explosion are indicators of a rapid chemical reaction taking place.
