Chemical because its made of chemicals like minerals and when the fire on the string hits the minerals then it forms a chemical reaction.
Yes, fireworks involve a chemical reaction where the materials inside the firework combine to produce light, heat, and sound. This chemical reaction is not reversible, so it is considered a chemical change rather than a physical change.
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.
it is a chemical change
Crushing charcoal into powder is a physical change, as it alters the size and shape of the charcoal without changing its chemical composition.
Chemical broooooooooooooooo niga

A firework undergoes both physical and chemical changes. The lighting of the firework involves a chemical reaction within the firework's composition to produce the colors and effects seen in the sky. The transformation of the firework materials into smoke and ash after the display represents a physical change.
It is a chemical change as it releases gases into the air.
It is a chemical reaction because it changes and the change can't be revesed
It is a chemical reaction because it changes and the change can't be revesed
Use of fireworks is a 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.
Fireworks involve both physical and chemical changes. The lighting of the firework (ignition) is a chemical change that triggers a series of reactions which results in the colorful display seen (physical change) as different elements are heated and produce light.
Definitely a chemical change, The elements in the firework undergo very rapid combustion (burning) which is a chemical change.
Yes, when dynamite explodes, it is an example of a chemical change. The chemical bonds within the dynamite molecules are broken and reformed during the explosion, resulting in the release of energy and the formation of new chemical compounds.
Yes, fireworks involve a chemical reaction where the materials inside the firework combine to produce light, heat, and sound. This chemical reaction is not reversible, so it is considered a chemical change rather than a physical change.
