You are a chemical! So actually you are the chemical!
chemical changes affect the chemical properties as well as composition of matter , that result in the formation of a new substance.
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.
Life is a complicated series of chemical reactions.
No, chemical changes cannot be reversed by physical changes. Chemical changes involve the formation of new substances with different properties, while physical changes only affect the state or appearance of a substance without changing its chemical composition. Once a chemical change occurs, it cannot be undone by a physical change.
Well a Chemical change means that what ever changes can't change back. For example if u have normal paper then burn it that's a chemical change and that's why a chemical change is so important.
They don't - which is why radioactive dating works.
A physical change is reversible and does not affect the composition of a substance. On the other hand, chemical change is irreversible and permanent. A substance undergoing a chemical change forms a new substance which has different composition than the original substance.

Changes can affect particles by altering their behavior, arrangement, or properties. For example, changes in temperature can cause particles to move faster or slower, while changes in pressure can affect the density and arrangement of particles. Additionally, changes in chemical composition can lead to the formation of new particles or the dissolution of existing ones.
Freezing/melting or evaporation/condensation, are physical changes that don't affect the chemical nature of the substances.
Chemical changes can be both good and bad. Some chemical changes are necessary for life to exist, such as in the process of digestion. However, some chemical changes can be harmful, such as those that occur in pollution or the degradation of materials.
