All physical changes are reversible.
chemical reactions are irreversible but physical changes are reversible
No, not all chemical reactions are reversible. Some reactions are irreversible, meaning they cannot easily be reversed to reform the original reactants.
Reversible reactions reach chemical equilibrium because the forward and reverse reactions occur at the same rate, leading to a balance in the concentrations of reactants and products.
Cooking involve irreversible chemical reactions.
irreversible
Yes, reversible chemical reactions exist.
some chemical changes can be reversed but they are hard to reverse usually
In a reversible reaction, the products can convert back into the reactants given appropriate conditions. This is often seen in chemical equilibrium where the forward and reverse reactions occur at the same rate.
Reversible reactions usually involve a reaction that changes the physical state of the substance, not the chemical properties
Digestion involve chemical reactions, it is a chemical and mechanical process and is irreversible.
Most cooking processes are chemical reactions. Generally, the reactions are non reversible and once cooked, food cannot be returned to an uncooked state. So, frying potatoes causes a non reversible chemical reaction. The question is not as precise as it might be. Changes can be physical or chemical. They can also be reversible or non reversible but it is important to note that many chemical changes are reversible just as many physical changes are reversible.
Chemical changes that involve physical changes, such as melting, boiling, or dissolving, are generally reversible. Reactions involving phase changes or reversible reactions where products can revert back to reactants under certain conditions are reversible. An example is the reaction between water and carbon dioxide to form carbonic acid, which can decompose back into water and carbon dioxide.
