∙ 6y agoThis is not a phrase we use. A chemical change is one which produces a new substance. A state change means conversion between physical states, solid liquid and gas. These are physical changes.

∙ 15y agoChanging from a Solid to a Liquid to a Gas is a physical change.

∙ 11y agoNo. Not necessarily. A substance can change state without a chemical reaction.

What is an indicator of a chemical reaction?
HEAT, Heat is the the number one indication of a reaction. Also, changes of state of matter and mass are also indicators of a chemical reaction. an example is when an iron fence rusts.
Is reaction with acid a physical or chemical property?
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).
Is rain turning to snow a chemical reaction?
No, it is a change of state.
What signs or indicators of chemical changes are shown in these reactions?
Chemical reactions can be obvious. First of all, listen: if you hear any sounds, such as a fizzing sound, that may be one indicator. Another is a change in color, or even state. If a solution is aqueous, and it precipitates (becomes a solid), that's also another indicator of a chemical reaction.
What are the characteristics of a chemical reaction with example?
5characteristics of chemical reaction 1, evolution of gas 2,formation of precipitate 3,change in temperature 4,change in colour 5,change in state

How can you tell the difference between a chemical reaction and not a chemical reaction?
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
Is melting a type of Chemical change?
no- melting is not a chemical change. It is merely a change in state of the same substance not a chemical reaction.
Is evaporation a chemical reaction?
No, it is a physical change of state. There is no change in chemical properties.
Is reaction with acid a physical or chemical property?
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).
Is rain turning to snow a chemical reaction?
No, it is a change of state.
Is water a chemical reaction or a physical 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.
What is chemical and physical reactions?
A physical reaction is were the current substance can be changed in state and then changed back easily to it's previous state, a chemical reaction is the opposite, it is difficult to change it back to its previous state.

What happens to make a chemical reaction?
In A Chemical Reaction the following take place a) there is evolution of a gas b) change in colour c) change in state d) change in temperature
Why isn't a change in mass an indicator of chemical change?
A change in mass is not always an indicator of a chemical change because mass is conserved in chemical reactions. The total mass of the reactants is equal to the total mass of the products. However, there are some exceptions where a change in mass can occur due to the release or absorption of gases or changes in the physical state (such as evaporation or condensation) during a chemical reaction.
What are the characteristics of a chemical reaction with example?
5characteristics of chemical reaction 1, evolution of gas 2,formation of precipitate 3,change in temperature 4,change in colour 5,change in state
