'Law of multiple Proportion was discovered by whom?
The law of multiple proportions was proposed by John Dalton in the early 19th century. It states that when elements combine to form compounds, the ratio of masses of one element that combines with a fixed mass of the other element can be expressed in small whole numbers.
What pair of substances best illustrates the law of multiple proportions?
Carbon monoxide (CO) and carbon dioxide (CO2) best illustrate the law of multiple proportions. In CO, there is 1 carbon atom to 1 oxygen atom, while in CO2, there are 1 carbon atom to 2 oxygen atoms. This shows that the ratio of masses between the two elements stays simple and consistent, as predicted by the law of multiple proportions.
What is the law that states that a chemical compound always contains the same elements in exactly the same proportions by w eight and mass?
The law you are referring to is the Law of Definite Proportions. This law states that a chemical compound always contains the same elements in the same proportions by mass, regardless of the source of the compound.
Dalton's fourth postulate states that atoms combine?
Dalton's fourth postulate states that atoms combine in simple whole-number ratios to form compounds. This postulate laid the foundation for the law of definite proportions and the law of multiple proportions in chemical reactions and helped in the development of modern atomic theory.
What experiments were used to prove the law of multiple proportions?
The experiments that were done to prove the law of definite proportions are called Proust's Law. These are several experiments conducted to combined different types of atoms in fixed proportions.
Who made the law of multiple proportions?
The law of multiple proportions was proposed by John Dalton in 1804; today this law has not a general validity.
1 Differentiate between The Law of Definite Proportions and The Law of Multiple Proportions?
Well definite is broad and multiple is more exact that's about what I can think of
Who developed the multiple proportions law?
The Law of Multiple Proportions was developed by John Dalton based on the Law of Definite Proportions, was part of what laid the groundwork for his atomic theory, and for the basis of chemical formulas for compounds.English chemist John Dalton
What is evidence that led to the law of multiple proportions?
the block wall
Who came up with the law of multiple proportions?
John Dalton
Who came up with law of multiple proportions?

What types of compounds are compared in the law of multiple proportions?
Water and hydrogen peroxide

What is multiple proportions?
The law of multiple proportions states that if two elements form more than one compound between them, then the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers. Two examples of the law of multiple proportions are carbon monoxide, CO, and carbon dioxide, CO2, and water, H2O, and hydrogen peroxide, H2O2.
How does hydrazine and ammonia illustrate the law of multiple proportions?
Hydrazine and ammonia are composed of the same elements but have different chemical and empirical formulas. Ammonia is NH3, Hydrazine is N2H4 they have the same elements but in a different ratio.
What are the experiments John Dalton carried out that led to the law of multiple proportions formulation.?
his nipples were hard
What proportions mean?
Two quantities are proportional if they vary in such a way that one of them is a constant multiple of the other.
