Chemical changes are considered unseen because they occur at the atomic level, changing the actual structure of the thing. This is in comparison to a physical change, which is visible.

Is changes in energy a chemical change?
Changes in energy themselves are not considered chemical changes. Instead, changes in energy may occur as a result of a chemical change taking place, such as in an exothermic or endothermic reaction where energy is either released or absorbed.
Why are changes considered unseen?

When is a reaction considered chemical?
A reaction is considered chemical when bonds between atoms are broken and new bonds are formed, resulting in a change in the chemical composition of the substances involved. Physical changes, on the other hand, do not involve changes in the chemical composition of the substances.
Are the changes in the state of matter chemical changes?
No, changes in state of matter (such as melting, freezing, boiling) are physical changes, not chemical changes. Chemical changes involve the formation of new substances with different chemical properties.
Differences between physical changes and chemical changes?
Physical changes are changes that affect the form of a chemical substance, such as changes in state or shape, without changing its chemical composition. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are often irreversible.

Why is burning of gas considered a chemical change?
All burning reactions involve chemical reactions (chemical changes).
When is a reaction considered chemical?
A reaction is considered chemical when bonds between atoms are broken and new bonds are formed, resulting in a change in the chemical composition of the substances involved. Physical changes, on the other hand, do not involve changes in the chemical composition of the substances.
What is The difference of physical science and chemical science?
Chemical science is the study of chemical changes, i.e. changes that involve electron transfer, bond formation and the thermodynamics and kinetics involved in these changes. Physical science is a broader term that encompasses the study of natural phenomena. Chemical science can be considered as a part of physical sciences.

Why is density considered physical property rather than a chemical property of matter?
The density doesn't involve chemical reactions, chemical changes. The density is a measurable property.
Are the changes in the state of matter chemical changes?
No, changes in state of matter (such as melting, freezing, boiling) are physical changes, not chemical changes. Chemical changes involve the formation of new substances with different chemical properties.
What are the chemical and physical changes of photosynthesis?
There are no physical changes. there are only chemical changes.
do oreos undertake any chemical changes?
Do Oreos undertake any chemical changes? Yes. How can Oreo be a chemical changes? Cooking involve chemical reactions, modifications of chemical molecules.
