Who is results demonstrated that elements combine in specific proportions because they are made of individual atoms?
The law of definite proportions was proposed by Joseph Proust, a French chemist, in the late 18th century. He demonstrated through experiments that elements combine in specific proportions by mass because they are composed of individual atoms with fixed ratios.
Who said that Elements combine in specific proportions?
John Dalton
What scientist said that elements combine in specific proportions?
The scientist who proposed the law of definite proportions was Joseph Proust. He stated that elements always combine in specific and fixed proportions by mass to form compounds.
Who wanted to know why elements combine in specific proportions?
John Dalton in 1803
Is a compound a substance of two or more elements bounded together in definite proportions?
A compound is a substance of two or more elements bounded together in definite atomical proportions
Do elements always combine in specific ratios?
The Law of Definite Proportions says that a given chemical compound always contains the same proportion by mass of its constituent elements. This is NOT the same as saying that elements always combine in a specific ratio, because they can combine in different ratios in different compounds. An example of this might be copper oxide which can be CuO or Cu2O, showing a different ratio of copper to oxygen. So, the answer to the question, as asked, is no, elements do not always combine in specific ratios.
Can any of the 112 known elements combine to form a mineral?
No. There are 13 elements that are either noble gases or are unstable in nature.
Elements combine in a specific proportion?
Chemical elements combine in specific ratios to form compounds. This is governed by the principles of stoichiometry and reflects the fixed ratio of atoms in a compound's chemical formula. The specific proportion of elements in a compound determines its properties and behavior.
What is stoichiomtry?
Stoichiometry is the study of the relative proportions of elements that combine during chemical reactions.
What is the law of multiple proportions in chemistry and examples of it?
When elements combine,they do so in a ratio of small whole numbers.
Is it true that the elements that make up a compound are always present in the same proportions?
Yes, that is true for compounds with a fixed chemical formula. In a compound, elements combine in specific ratios based on their valencies to form stable structures. This is known as the law of definite proportions.
What Elements combine in fixed mass ratios to form compounds This must mean that elements?
In chemical compounds, elements combine in fixed ratios by mass to form stable, distinct substances. This observation is summarized in the law of definite proportions, which states that a compound is always composed of the same elements in the same proportions by mass. This principle demonstrates the predictable and reproducible nature of chemical reactions.
