mittekeemilised

Mittekeemilised, also known as non-chemicals, refer to substances or materials that do not contain any chemical compounds. This category includes elements in their natural, uncombined state, such as oxygen, hydrogen, and gold. Non-chemicals are often used in various applications due to their unique properties and lack of reactivity. For example, noble gases like helium and neon are used in lighting and medical applications due to their inert nature. Additionally, some non-chemicals, like water (H2O), are essential for life and have numerous industrial uses. In contrast to chemicals, non-chemicals do not undergo chemical reactions and do not form new substances. They are often used in scenarios where chemical reactivity is undesirable, such as in certain types of packaging or as inert fillers. The study of non-chemicals is a branch of chemistry that focuses on their properties, behavior, and applications.
