When a firework explodes, a series of chemical reactions occur, primarily involving the rapid combustion of oxidizers and fuels. The heat from the ignition initiates these reactions, producing gases, light, and heat. This results in the release of energy, which creates the vibrant colors and loud sounds associated with fireworks. Additionally, the formation of new compounds, such as metal salts, contributes to the visual effects.

Most chemical changes happen between molecules, so they are unseen.
Chemical changes in a structure are most likely to happen during a chemical reaction where bonds are broken and formed between atoms. This can occur when new substances are formed, leading to a change in the composition and properties of the structure.
No, chemical changes can occur at various temperatures depending on the specific reaction. While many chemical reactions do happen at higher temperatures to provide enough energy for the reaction to occur, there are also reactions that occur at lower temperatures. Temperature is just one factor that can influence the rate of a chemical reaction.
Food undergoes physical, chemical, and biological changes during storage and preparation. Physical changes may include freezing, heating, or grinding. Chemical changes involve oxidation, browning, or fermentation. Biological changes occur when microbes grow and spoil the food.

Cytoplasm
A fire is a chemical change due to the irreversible changes that happen.
Cooking involves chemical changes.
volcanic eruption
The majority of these changes are recognized.
it explodes....yay.
something
It begins to boil.
magnesium sulphate
It explodes
