Chemical reactions are at the core of chemistry and the world around us. In a chemical reaction, substances interact and change into new substances, releasing or absorbing energy in the process. From combustion to photosynthesis, reactions are essential for life on Earth.
Understanding chemical reactions helps scientists predict how substances will behave, develop new materials, and create life-saving medicines. Whether it's the reaction between baking soda and vinegar or the complex processes inside our cells, chemical reactions are happening all around us.
