State the Law of Multiple Proportion?
Law of Multiple Proportions – Example: The law of multiple proportions states that when two elements form more than one compound, the masses of one element that combine with a fixed mass of the other element are in simple whole number ratios.
Examples of Law of Multiple Proportions
In chemistry, the law of multiple proportions states that when two elements form more than one compound, the masses of one element that combine with a fixed mass of the other element are in ratios of small whole numbers.
For example, when chlorine and potassium combine to form two different compounds, potassium chloride (KCl) and potassium chromate (K2CrO4), the ratios of chlorine to potassium are always 1:1 in KCl and 2:1 in K2CrO4.
Dalton’s Atomic Theory
Dalton’s Atomic Theory is the theory that states that all matter is composed of atoms and that atoms are indivisible and indestructible.
Important Points of Dalton’s Atomic Theory
Dalton’s Atomic Theory was an important scientific advance because it provided new way of thinking about structure of matter. Dalton’s theory proposed that atoms were indivisible and indestructible, and that all atoms of a given element were identical. This was a major departure from prevailing view that atoms were made up of smaller particles. And therefore they could divided and destroyed. Dalton’s theory also proposed that atoms of different elements had different weights, and that these weights determined the properties of the elements. This was a major advance over the previous view that all atoms were the same.
FAQs
1. What is the law of multiple proportions?
The law of multiple proportions is a chemical law that states that when two or more elements combine to form more than one compound. The ratios of the masses of the elements in the different compounds are simple whole numbers.
2. What are some examples of the law of multiple proportions?
One example of law of multiple proportions is that when carbon and oxygen combine to form carbon dioxide and carbon monoxide. The ratio of mass of carbon to mass of oxygen in carbon dioxide is always 1:2. While the ratio of the mass of carbon to the mass of oxygen in carbon monoxide is always 1:1.
3. What is the significance of the law of multiple proportions?
The law of multiple proportions significant because it helps to establish the atomic theory of matter. Which states that matter made up of atoms that cannot divided into smaller particles. The law of multiple proportions provides evidence for this theory by showing that when elements combine to form compounds, the ratios of masses of the elements in the different compounds are always simple whole numbers.
