chemical
This is a chemical change because a chemical reaction occurs, creating a whole new substance (carbon dioxide).
a physical reaction for the chemical structure is not changing.
The reaction of chemicals in a battery to power a flashlight is a chemical change. This is because the chemicals in the battery undergo a chemical reaction to produce electricity, which powers the flashlight.
What do u mean by chemical or physical reaction... Please give me an answer so i can give you the answer.
Water is not a reaction at all. If you mean to ask if a state change in water is chemical or physical, it is physical.
chemical
It's a chemical reaction
It is a physical property not a reaction
Electricity is not a physical or chemical change itself, but rather a form of energy that can result from both physical and chemical processes. When electrons flow through a conductor, it is a physical change, as the electrons are simply moving from one place to another. However, in some cases, electricity can also be produced through chemical reactions, such as in batteries, in which case it involves a chemical change.
Scientists make a distinction: physical absorption (without chemical reaction) and chemical absorption (involving a chemical reaction).
Vapor is not a chemical reaction itself. It is the gaseous state of a substance that was previously in liquid or solid form. The process of creating vapor from a liquid or solid can involve a physical change (such as evaporation) rather than a chemical reaction.
A battery produces electricity through a chemical reaction that occurs inside it. When the battery is connected to a circuit, the reaction causes electrons to flow from one terminal to the other, creating an electric current. This flow of electrons is what we perceive as electricity.
