Some indicators of a chemical reaction are:
- change of color
- change of odor
- release of a gas
- change of the temperature
- change of the viscosity
- formation of a precipitate
- change of general appearance
- possible explosion - possible chemiluminescence - formation of new compounds
When there is no observable change in the physical or chemical properties of the reactants after they are mixed together, it indicates that there is no reaction occurring. This lack of reaction can be confirmed by the absence of any signs such as color change, gas evolution, temperature change, or formation of a precipitate. In such cases, the reactants typically remain chemically unchanged.
A colour change occurs. A precipitate can be seen. Gas bubbles can be seen.

Is chemical reaction alive?
No. A chemical reaction is not alive.
How can you know this is a chemical reaction?
Evidence of a chemical reaction include the following: formation of a precipitate formation of a gas change in temperature change in color
What is the chemical reaction called where water is removed during the reaction?
This chemical reaction is called dehydration.
If you say 'oxygen gas supports combustion' are you talking about a chemical or physical reaction?
Combustion is a hemical reaction.
When energy is absorbed during a chemical reaction the reaction is classified as what reaction?
Endothermic reaction.
What is the correct balanced chemical equation for this reaction?
To provide the balanced chemical equation, I would need to know the specific reaction you are referring to. Can you please provide the reactants and products involved in the reaction?
Is chemical reaction alive?
No. A chemical reaction is not alive.
How does an engine have a chemical reaction?
Combustion is a chemical reaction.
What is cheamical reaction?
a chemical reaction is a reaction were the two chemicals change into a new chemical.
In a chemical reaction the reaction must do what?
The reaction must change the chemical nature of reactants.
How can you know this is a chemical reaction?
Evidence of a chemical reaction include the following: formation of a precipitate formation of a gas change in temperature change in color
What is a chemical change also referred to as?
Chemical reaction
An amtom undergoes a reaction ant attains a more stable from how do you know is it was chemical or nuclear reaction?
If an atom undergoes a chemical reaction, it involves rearrangement of electrons in the outer shell to form new chemical bonds. On the other hand, if it undergoes a nuclear reaction, it involves changes in the atomic nuclei, resulting in the formation of different elements or isotopes. To determine whether it was a chemical or nuclear reaction, observe whether there are changes in the electron configuration or in the atomic number and mass of the atom.
Is something rotting a chemical reaction?
yes, something rotting is a chemical reaction because it undergo oxidation reaction. the reaction is a part of redox reaction
What are the five ways to know that chemical reaction happened?
don't know
How does a chemical equation show that a chemical reaction has occurred?
A chemical equation shows that chemical reaction has occurred as new substances have been formed from the reagents. A chemical equation has two sides before reaction and after reaction, if there is any change from the before reaction side to the after reaction side, it indicates that a chemical reaction has just occurred.
What is the chemical reaction called where water is removed during the reaction?
This chemical reaction is called dehydration.
