A chemical change is one where new compounds or atoms (products) are being formed from other compounds/atoms (reactants). Fireworks involve combustion, which is a type of chemical reaction because the reactants are being changed into different products.
NOTE: don't mistake this for a nuclear reaction, all chemical reactions have the same number of each element on each side, but many form elements in their pure form (such as Hydrogen) from a reactant like H2O.
Explosiveness (not oxploziveness!) is a property, not a change. But it is a chemical property.
Chemical change. A good hint for this one is that there is fire involved, which usually means that the chemical itself is being changed. The constituent materials oxidize (burning quickly - explosion - is very rapid oxidization) and form new compounds i.e. the chemicals change.
It is a chemical change because it has oxidation and combustion.Both. There's a rapid chemical change which liberates a lot of heat quickly and some of the material may become a gas, the physical change.Read more: When_firework_explodes_is_physical_change_or_chemical_changeNote: release of heat is not a physical change but only a consequence of a chemical change.
The explosion of fireworks is a chemical change. This occurs because the combustible materials in the fireworks undergo a chemical reaction when ignited, resulting in the production of new substances, such as gases and light. The release of heat and light is also indicative of this chemical reaction. Physical changes, in contrast, do not involve the formation of new substances.

A physical change stays the same like tearing paper A chemical change makes the substance something new like fireworks explode (fireworks change to explosion)

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.

Are fireworks a chemical change or a physical change? Fireworks are a chemical change because once you lite it, it reacts to the fire.eat dodo doodadsdodo doodads

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.
Use of fireworks is a chemical change.
It is a chemical change.
