A chemical reaction is a process that involves the rearrangement of the molecular or ionic structure of a substance, resulting in the formation of one or more new substances. During a chemical reaction, the original substances, called reactants, are transformed into different substances, known as products. This transformation occurs due to the breaking and forming of chemical bonds within the reactant molecules. Chemical reactions are essential for various natural processes and industrial applications, including the production of energy, food, and materials.
Key Concepts:
Reactants: The original substances that participate in a chemical reaction.
Products: The new substances formed as a result of the chemical reaction.
Chemical Bonds: The forces that hold atoms together in a molecule or compound.
What are the different types of energychanges that can occur during a chemical reaction?
Can you identify examples of different types of chemical reactions in everyday life?
What are the factors that can affect the rate of a chemical reaction?
By studying these concepts, you will gain a comprehensive understanding of chemical reactions and their significance in various natural and human-made processes.
History and Nature of Science: A student should understand the history and nature of science. A student who meets the content standard should:
Develop an understanding that historical perspectives of scientific explanations demonstrate that scientific knowledge changes over time, building on prior knowledge.
Develop an understanding that scientific knowledge is ongoing and subject to change as new evidence becomes available through experimental and/or observational confirmation(s).
