There are a huge number of chemical reactions, and the outcomes can vary widely from something that can hardly be noticed to a violent explosion.
some chemical changes can be reversed but they are hard to reverse usually
This name is chemical reactions.
Do Oreos undertake any chemical changes? Yes. How can Oreo be a chemical changes? Cooking involve chemical reactions, modifications of chemical molecules.
Chemical bonds always break in chemical reactions, causing changes in energy.
Chemical reactions are of course chemical changes.
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
No, chemical reactions do not produce new atoms. Atoms are rearranged in chemical reactions to form new substances, but the number of atoms remains constant before and after the reaction. This is known as the Law of Conservation of Mass.
yes chemical reactions in order to induce a chemical reaction that might normally take a long time
Chlorine
It is not mandatory.
Yes. Refer to endothermic and exothermic reactions to learn more.
