Answer:
Common examples are water (H2O), salt (sodium chloride, NaCl), methane (CH4). The symbols indicate which elements the compounds contain and the number tells you the ratio in which the atoms of the elements combine. A mixture is made by simply mixing together elements and compounds. No new chemical bonds are formed.
