Chemicals

Chemicals are substances with a defined molecular composition, produced or used in a variety of industrial, scientific, and everyday applications. They exist in solid, liquid, or gaseous forms, often interacting with other substances to create new compounds or effect changes. The term encompasses both naturally occurring substances and those synthesized by humans. Understanding chemical properties, reactions, and their effects is fundamental to fields such as medicine, agriculture, manufacturing, and environmental science. The study of chemicals contributes significantly to advancements in technology and helps us comprehend the intricate world around us, including living organisms and inanimate matter. Chemical safety and the responsible handling of these substances are paramount, given their potential to pose risks to human health and the environment if not properly managed.
