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.


Is blowing up a balloon a physical or chemical change and why?

Blowing up a balloon is a physical change because the air being blown into the balloon does not alter the chemical composition of the balloon material. The change is reversible, as the balloon can be deflated and reinflated multiple times without changing its chemical makeup.


Is breaking a glow stick a chemical or physical change?

It's a chemical change--there's a glass ampule in the glow stick. and it's got one chemical in it. Around it is another chemical. When you break the glow stick the two chemicals mix, and the glow happens.


What is the difference between physical and chemical changes in terms of what happens to the matter involved in each change?

In a physical change, the chemical composition of the substance does not change, it merely changes form. In a chemical change, the chemical formula changes so that fundamental properties such as density and molar mass change.

physical change since the egg and the contents inside do not become a new substance they remain the same only thing is that the shape or the appearance or the physical structure changes that is why it is called as a physical change not chemical because its internal composition is the same

Is a pellet of sodium is sliced in two a physical change or a chemical change?

Physical, because each slice of pellet is still the same chemically: you have merely divided your one sodium block into two blocks of sodium. If it were chemical, some kind of notable chemical difference would have occurred (you would no longer have sodium, but something else).
