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.
Because chemical potential energy stored in the fireworks is transferred into heat, sound, kinetic and light energy when the fireworks explode.
Yes, fireworks are an example of a chemical change because they involve one compound in a combustion reaction to form another.
Simply the burning of the explosive. Combustion is a chemical change.
because with burning oxides are created - so all burning is a chemical change.
when a chemical change takes place, there is formation of gas, light and sometimes sound,as per the statement ad properties of chemical change
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.
Fireworks that are set off are a chemical 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

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

No. Fireworks are an example of a chemical change called combustion.

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.
when fireworks go off, the energy released show a chemical reaction. gasses such as carbon dioxide and particles of smoke go up in the air.
