Reaction is more often used for chemical change, but it is also used in the physics law, "For every action there is an equal and opposite reaction."
a physical reaction for the chemical structure is not changing.
In a chemical reaction something new is created. A chemical change is inreversible where as a physical change is. In a physical change nothing new is formed.
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.
A physical change is one in which the chemical composition of the substance does not change. A chemical change is one in which new products are formed with their own unique chemical compositions and properties.
Both. A chemical reaction occurs & a physical change is noticeable.
Chemical change
This is a chemical reaction, a chemical change.
A physical reaction is when no new substances are formed, there is a change of state eg ice melting to a liquid. A chemical change is when the reaction forms a new substance. eg gas bubbles. An acid reaction can be both. You need to look at the reaction taking place, look for change of state (physical) or any colour change or gas bubbles (chemical).
no its a chemical reaction
It is considered a physical change. A chemical change involves chemical reactions that change the substance into another substance. A physical change typically only modifies the form or phase.
It is a physical change. There is no chemical reaction whatsoever.
A chemical reaction will do the following; Change colour Create smoke A non chemical reaction (Physical Reaction) will do the following; Change State Be able to change back to the original materials
