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 chemiluminiscence
- formation of new compounds
Transmutation of elements refers to the conversion of one chemical element into another. This occurs in nuclear reactions or through radioactive decay.
Chemical.
In a chemical reaction the actual reactants are also called the starting materials or interactants. These are the materials necessary for the reaction to happen and undergo chemical change.
If you mean changing one element into another, like uranium 238 into plutonium 239, which happens in nuclear reactors, the word is 'transmutation'. Otherwise many chemical reactions form new substances, without the elements involved changing, and these would be called 'chemical reactions'.
this is a chemical change cause you can't return it back to solid salt
This is a chemical property of an element. It indicates how an element interacts with other substances. In this case, the element does not undergo a chemical change when exposed to hydrogen.
A chimical property that indicates weather a substance can undergo chimical change
Hg is not a change, it is an element. It can undergo changes, both physical and chemical.
I believe the word you are searching for is Reactivity?
Magnesium is not a change of any sort. It is a metallic element that can undergo both physical an chemical changes.
Catalysts doesn't undergo a chemical change during a chemical reaction.
Substances that undergo chemical change are called reactants.
An element is a pure substance that is the simplest form of matter and cannot be broken down into simpler substances by chemical means. Therefore, an element is not considered to undergo a physical or chemical change. Additionally, elements are considered homogeneous because they consist of only one type of atom throughout.
A chemical property of a substance refers to its ability to undergo a chemical change or reaction to form new substances. This property is related to the substance's composition and arrangement of atoms. Examples of chemical properties include reactivity with other substances, flammability, and acidity or basicity.
A catalyst doesn't undergo a chemical change during a chemical reaction.
A catalyst undergoes no chemical change during a chemical reaction.
Bread is not a change. It is a mixture of substances that can undergo physical and chemical changes.
