Compound:
* Definition: A substance composed of two or more different elements chemically bonded together in a fixed ratio.
* Examples: Water (H₂O), salt (NaCl), glucose (C₆H₁₂O₆)
* Key Feature: A compound's properties are distinct from the elements it contains. For instance, water is a liquid at room temperature, while hydrogen and oxygen are gases.
Formula:
* Definition: A symbolic representation of a compound or molecule, showing the types and number of atoms present.
* Examples: H₂O (water), CO₂ (carbon dioxide), CH₄ (methane)
* Key Feature: A formula provides a concise way to describe the composition of a substance.
Connection:
A compound and a formula are connected because a formula describes a compound. The formula tells us what elements are present in the compound and in what ratio. For example, the formula H₂O tells us that water is made up of two hydrogen atoms and one oxygen atom.
To summarize:
* A compound is a substance with a specific composition and unique properties.
* A formula is a symbolic representation of a compound's composition.
