Study Notes
Differences Between Organic and Inorganic Chemistry
- Organic chemistry studies substances containing carbon, essential for all living organisms.
- Organic compounds include gasoline, synthetic fabrics, plastics, and pesticides, originating from fossilized plants and animals.
- Most organic substances are flammable due to their chemical structure.
- Inorganic chemistry focuses on substances that do not contain carbon but may include hydrogen.
- Inorganic compounds encompass metals, minerals, water, air, and ammonia and are not derived from living organisms.
- Inorganic substances are non-flammable and do not exhibit the same biological processes as organic compounds.
Definition of Matter
- Matter is anything that occupies space and has mass.
- Exists in three states: solid, liquid, or gas.
- Physical properties of matter include qualities that can be perceived through the senses, such as touch, taste, smell, and sight.
- Energy, such as light and electricity, is not classified as matter since it does not possess mass, though it can affect matter.
- The chemical properties of matter can only be observed during chemical changes or reactions.
Elements
- An element is the most basic form of chemical matter, consisting of only one type of atom.
- It cannot be chemically broken down into simpler substances without losing its identity.
- There are currently 118 known elements, of which 98 occur naturally on Earth.
- Synthetic elements are artificially created through chemical processes or synthesis.
