A chemical reaction changes the actual chemical make-up of a molecule while a physical reaction only changed the physical state of a molecule, the atomic make-up in the molecule stays the same. (ex: H20(l) ---heat--> H20(g))
No, it's a physical reaction because it is still water just in a different form.
Color is a physical property of an object that arises from the reflection of light off its surface. It is not a chemical reaction, but rather how our eyes perceive different wavelengths of light interacting with the molecules in the object.
The reaction between aluminum and copper chloride is a chemical change. During the reaction, a chemical reaction occurs resulting in the formation of new substances with different properties than the original reactants. This is different from a physical change where substances maintain their original properties.
a physical reaction for the chemical structure is not changing.
No, freezing involves phase change, which is a physical change. There is no chemical reaction, as the basic chemistry is unchanged it is still the same material in a different physical state.
What do u mean by chemical or physical reaction... Please give me an answer so i can give you the answer.
A product is a substance formed during a chemical reaction. It is the result of the reaction's course and might have different physical or chemical properties than the reactants.
chemical
It's a chemical reaction
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.
It is a physical property not a reaction
In a chemical reaction, atoms are rearranged, such that some atoms get out of some molecules and join other molecules.
