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
What else can I help you with?
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
Is chemical reaction alive?
No. A chemical reaction is not alive.
If you say 'oxygen gas supports combustion' are you talking about a chemical or physical reaction?
Combustion is a hemical reaction.
What is the chemical reaction called where water is removed during the reaction?
This chemical reaction is called dehydration.
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?
How can you know this is a 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.
How does an engine have a chemical reaction?
Combustion is a chemical reaction.
Is chemical reaction alive?
No. A chemical reaction is not alive.
In a chemical reaction the reaction must do what?
The reaction must change the chemical nature of reactants.
What is cheamical reaction?
a chemical reaction is a reaction were the two chemicals change into a new chemical.
What are the five ways to know that chemical reaction happened?
don't know
What is a chemical change also referred to as?
Chemical reaction
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
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.
If you say 'oxygen gas supports combustion' are you talking about a chemical or physical reaction?
Combustion is a hemical reaction.
