Example 1

easy
Define a compound and explain how it differs from both an element and a mixture.

Solution

  1. 1
    A compound is a pure substance composed of two or more different elements chemically bonded in a fixed ratio.
  2. 2
    Unlike an element, a compound contains more than one type of atom. Unlike a mixture, a compound has a definite composition that cannot vary.
  3. 3
    Compounds can only be separated into their elements by chemical means (e.g., electrolysis), not by physical means like filtering or distilling.

Answer

Compound: fixed ratio, chemically bonded, two or more elements\text{Compound: fixed ratio, chemically bonded, two or more elements}
The law of definite proportions states that a compound always contains the same elements in the same proportions by mass, regardless of the source or method of preparation.
