The chemical reaction involved is the same, but the speed at which it happens and the fact that many such reactions occur at the same time are what causes an explosion.

Why is explosion a chemical change?
UPLOAD PHOTO AND GET THE ANSWER NOW! Solution : Explosion of a cracker is a chemical change because the explosive reactants are transformed into gaseous products along with heat, light and sound which cannot be reversed. Hence, it is a chemical change.
Is an explosion a chemical energy?
An explosion is a type of spontaneous chemical reaction that, once initiated, is driven by both a large exothermic change (great release of heat) and a large positive entropy change (great quantities of gases are released) in going from reactants to products, thereby constituting a thermodynamically favorable process …
Is the ability to explode a physical or chemical property?
Flammability. The ability of an element to ignite or explode is called flammability, and this is another chemical property.
What is an explosion in physics?
When an object explodes, it breaks up into more than one piece and it therefore changes its shape. Explosions occur when energy is transformed from one kind e.g. chemical potential energy to another e.g. heat energy or kinetic energy extremely quickly.
How are explosives classified?
The class of explosives includes: a) explosive chemicals; b) explosive items, except devices containing explosive chemicals in such quantity or of such a character that their inadvertent or accidental ignition or initiation does not cause any effect external to the device either by projection, fire, smoke, heat or loud …
Which part of an explosion is not considered a chemical change?
It’s a reaction with oxygen to form new substances. So Choice B is our answer expansion is a physical change.
Is exploding dynamite a chemical or physical property?
While the explosion of dynamite, it releases more energy. Therefore, we can say that, Explosion of dynamite is a chemical change.
What causes an explosion?
An explosion is a rapid expansion of gases. Many explosions occur when gases are exposed to a source of heat- such as fire, sparks, even static elec- tricity-or an increase in pressure. Explosions can also be caused by chemical reactions.
What happens when an explosion occurs?
An explosion is a rapid expansion in volume associated with an extremely vigorous outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Supersonic explosions created by high explosives are known as detonations and travel through shock waves.
What is the most explosive chemical?
Azidoazide azide is the most explosive chemical compound ever created. It is part of a class of chemicals known as high-nitrogen energetic materials, and it gets its “bang” from the 14 nitrogen atoms that compose it in a loosely bound state.
Why are explosions exothermic?
When a fuel is burning, it releases heat, which can easily be felt. An explosion is also an exothermic reaction. Even if the end result of an explosion is the high pressure generated that pushes everything away from its seat, heat is first produced in great magnitude. All combustion reactions are exothermic.
What is an example of chemical property?
The change of one type of matter into another type (or the inability to change) is a chemical property. Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion.
What are the 4 chemical properties?
Flammability. Heat of combustion. Enthalpy of formation. Chemical stability under specific conditions.
What is an example of physical property?
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.
What is meant by explosion in chemistry?
An explosion is defined as the rapid increase in volume and release of energy in an extreme manner.
What is explosion Short answer?
An explosion is a rapid increase in volume and release of energy. in an extreme manner, usually with the generation of high temperature and the release of gases. examples-fireworks(crackers)
What is the meaning of explosive in chemistry?
1. An explosive substance is a solid or liquid substance (or mixture of substances) which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings.
Is explosive a chemical hazard?
The OSHA Laboratory Standard defines an explosive as a chemical that causes a sudden, almost instantaneous release of pressure, gas, and heat when subjected to sudden shock, pressure, or high temperature. Under the Department of Transportation (DOT) hazard class system, explosives are listed as hazard class 1.
What is an example of a chemical explosion?
Examples include primary explosives such as nitroglycerin that can detonate with little or no stimulus and secondary explosives such as dynamite (trinitrotoluene, TNT) that require a strong shock (from a detonator such as a blasting cap).
What type of chemical reaction is an explosive?
A chemical explosion is basically a combustion reaction, but not all materials capable of combustion reactions can be used as military explosives.
What are the 3 types of explosives?
- blasting and bulk explosives (explosives used for commercial blasting applications or for their manufacture);
- perforating explosives (intended for use in the oil and gas well industry);
- special-application explosives (high explosives used for other applications, including primary explosives).
Is gasoline exploding a chemical change?
Gasoline burns, reacting with oxygen in the atmosphere, generating light, heat, and converting the carbon-based molecules into carbon dioxide gas and water vapor. When substances combine like this and undergo chemical changes, we say that a chemical reaction has occurred.
What are examples of chemical changes?
Burning, cooking, rusting and rotting are examples of chemical changes.
What two chemicals can make an explosion?
This list includes obvious explosive materials such as 2,4,6-trinitrotoluene (TNT), lead azide, and mercury fulminate. The list also includes more common laboratory chemicals in dried out or non-reagent form such as dinitrophenol, picric acid, and sodium azide.
