this is because the body needs to keep on growing hence the chemical processes that result to growth should keep reacting to support metabolism and life,incase we say the chemical reactions are reversed, then it would mean that we grow back to young from old age which is totally impossible....For processes like respiration and excretion in the body, main source of energy which is food must be broken down to give out energy, in case we say the energy could be reversed back to food and vomited out then that would mean no energy to support life hence automatic death. what do you think??
some chemical changes can be reversed but they are hard to reverse usually
All chemical changes involve the formation of new substances with different properties. They typically involve changes in the arrangement of atoms and the breaking and forming of chemical bonds. Chemical changes are often irreversible and are accompanied by changes in energy.
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.
irreversible
Irreversible changes.
Irreversible changes are changes which can not be turned back yo normal. These are chemical changes because the particles of the material have changed completely.

A fire is a chemical change due to the irreversible changes that happen.
chemical reactions are irreversible but physical changes are reversible
Rusting is a chemical property because it is irreversible. It changes the identity of the substance.
Yes because it is a chemical reaction and these reactions are irreversible

"The problems you caused are irreversible; they can never be remedied."
no, physical. The steam can return to water if cooled. Chemical changes are irreversible.

Yes. Chemical changes are irreversible, but physical changes can easily be changed back
