The explosion of fireworks is an example of chemical change. During a chemical change, substances are changed into different substances. Another words, the composition of the substance changes.
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 dynamite exploding a physical or chemical property?
While the explosion of dynamite, it releases more energy. Therefore, we can say that, Explosion of dynamite is a chemical change.
Is explosiveness a physical property of matter?
Properties that describe how matter changes into a completely new, different substance are chemical properties. Flammability and reactivity are examples of chemical properties.
Is explosion a physical property?
An Explosion Is a Chemical Reaction.
What are the properties of an explosion?
These properties are: detonation velocity, density, detonation pressure, water resistance, and fume class. For a given explosive, these properties vary with the manufacturer.
Is an explosion a chemical reaction?
One more important section related to combustion is the “explosive” chemical. Explosives are substances that undergo a rapid oxidation reaction with the production of large quantities of gases. It is the sudden buildup of gas pressure (see products above) that constitutes the nature of an explosion.
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.
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.
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 chemicals are explosive?
- Compounds containing the functional groups azide, acetylide, diazo, nitroso, haloamine, peroxide, and ozonide.
- Di- and Tri-nitro compounds.
- Peroxide forming compounds.
- Picric acid (dry)
- 2,4-Dinitrophenylhydrazine (dry)
- Benzoyl peroxide (dry)
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.
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 …
What are the 10 physical chemical properties?
Physical properties of matter include color, hardness, malleability, solubility, electrical conductivity, density, melting point, and boiling point. For the elements, color does not vary much from one element to the next.
What are chemical properties examples?
Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion. Iron, for example, combines with oxygen in the presence of water to form rust; chromium does not oxidize (Figure 3).
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 are the 7 examples of physical properties?
Examples of physical properties are: color, smell, freezing point, boiling point, melting point, infra-red spectrum, attraction (paramagnetic) or repulsion (diamagnetic) to magnets, opacity, viscosity and density. There are many more examples.
What are the 4 chemical properties?
Flammability. Heat of combustion. Enthalpy of formation. Chemical stability under specific conditions.
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.
What is the chemical equation for an explosion?
C7H5N3O6 6CO + 5/2 H2 + 3/2 N2 + C. The total amount of energy released in the reaction is called the heat of explosion.
Is explosion a type of combustion?
Explosive Combustion happens very rapidly releasing enormous amounts of heat, light, and sound energy. This combustion process is simply can be said as an explosion. During this combustion, gases that are released will spread quickly resulting in sound energy.
What is explosive science?
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure.
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)
