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.
During a chemical change the existing atoms of the products (the chemicals of the fireworks) are rearranged to form new combinations of atom. This new substances created usually have much different properties than the original substances. You can often tell that a chemical change has occurred if there is a large change in temperature (think fire in the firework) or a phase is produced (the expanding gases that blow the firework apart). The emission of light is also an indication that new substances have been produced.
Burning a sparkler is chemical change because once you have burned it you cannot re-burn it again and therefore it is chemical change and not physical change because physical change means you can physicaly seperate the different particles like if you have a bag full of jelly tots and smarties you can physically take out the smarties. Chemical change however is when a new product is formed meaning it cannot be taken back to its original form.
Explosiveness (not oxploziveness!) is a property, not a change. But it is a chemical property.
Fireworks involve both physical and chemical changes. The initial explosion and creation of light is a chemical change due to the combustion of materials in the fireworks. The colors produced by different compounds burning are a result of the release of energy and are considered a physical change.
Fireworks involve both chemical and physical changes. When the fireworks explode, chemical reactions occur between the different compounds in the fireworks, resulting in new substances being formed. Additionally, the release of light and heat during the explosion is a physical change.

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
chemical
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.
