Study Notes
Chemical Reactions
- A chemical reaction involves a transformation process where one or more reactants are converted into products.
- Reactants are the initial substances that undergo change during the reaction.
- Products are the new substances formed as a result of the chemical reaction.
- Substances involved in chemical reactions can be chemical elements (e.g., oxygen, hydrogen) or compounds (e.g., water, carbon dioxide).
- The process of a chemical reaction includes rearranging the atoms of the reactants to form different substances.
- Chemical reactions are fundamental processes in chemistry that illustrate how matter changes and interacts.
