Chemical transformations

Chemical transformations occur when substances change their structure at the molecular level, forming new substances with different properties. This involves breaking old bonds and forming new ones, often influenced by factors like heat, light, or catalysts. For example, burning wood turns it into ash, gases, and heat—distinct new substances. These processes are essential in nature and industry, enabling the creation of medicines, fuels, and materials. Overall, chemical transformations are the fundamental changes that turn raw materials into useful products by rearranging their atoms.
