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.
An exploding firecracker represents a chemical change because it involves a chemical reaction that produces new substances with different properties from the original firecracker.
phyical, because when you let go of the rubber band it returns to its original form
physical. no chemical reactions are going on and it is still a rubber band, it is just changing form, not what it is made of.
Setting off fireworks is a chemical change due to the fire combining with the explosives to change the full characteristics of all molecules
Rubber is not a change of any sort. It is a mixture of organic polymers that can undergo physical and chemical changes.

Are exploding fireworks an example of a physical or chemical change?
Exploding fireworks are an example of a chemical change. The chemical compounds within the fireworks undergo a chemical reaction when ignited, resulting in a new substance being formed that releases energy in the form of heat and light.
Is a bomb exploding a chemical or physical change?
It is usually a chemical change.
When a firecracker explodes giving off light and heat and breaking the wrapper into many pieces is that a physical change chemical change or both?
This is both a physical and chemical change. The explosion involves the release of energy (heat and light), which is a chemical change due to the breaking of chemical bonds. The breaking of the wrapper into many pieces is a physical change as it does not involve any change in the chemical composition of the materials.
Is exploding dynamite a physical or chemical change?
Exploding dynamite is a chemical change because the chemical composition of the dynamite changes due to the rapid reaction that occurs when it detonates. This results in the release of energy and the formation of new substances.
Is the explosiveness of fireworks a physical or chemical change?
The explosiveness of fireworks is a chemical change. It occurs when the chemical compounds in the fireworks undergo a rapid chemical reaction, resulting in the release of energy in the form of heat, light, and sound.
Is exploding a firecracker chemical change?
Yes, because there is a rearanging of molecules and atoms.
Is igniting a firecracker a chemical change?
Yes, igniting a firecracker is a chemical change. Burning or exploding the firecracker causes a chemical reaction that changes the composition of the materials inside the firecracker, releasing energy in the form of heat, light, and sound.
Is exploding of fireworks a chemical of physical change?
It is a chemical change.
Is exploding a physical change?
no its a chemical reaction
Is dynimite exploding a chemilcal or physical change?
Dynamite exploding is a chemical change called combustion.
When a fire cracker explodes is it a chemical change?
It is a chemical reaction because it changes and the change can't be revesed
Is exploding of fireworks a physical or chemical change?
I guess it is a chemical change as the exploded fireworks cant be regained back which is possible in a physical change and not in a chemical change.
Is fuel exploding a chemical or physical change?
Fuel exploding is a violent Chemical Reaction when fuel is reacted with atmospheric oxygen.
Is firework exploding physical or chemical change?
It is a chemical reaction because it changes and the change can't be revesed
