Law of Multiple Proportions
- Two elements, A and X, can form different compounds by combining in different proportions.
- These combinations can be represented as a ratio.
- For example
- A molecule of carbon dioxide (CO2) has a ratio of one C atom to every two atoms of oxygen or 1:2.
- A molecule of hydrogen peroxide (CO) has a ratio of one C atom to one atom of oxygen or 1:1
