The statement that a chemical compound always contains the same elements in exactly the same proportions is called the law of?
"In chemistry, the law of definite proportions and also the elements, sometimes called Proust's Law, states that a chemical compoundChemical_compoundalways contains exactly the same proportion of elementsChemical_elementby mass. An equivalent statement is the law of constant composition, which states that all samples of a given chemical compound have the same elemental composition." - Wikipedia
Who proposed the law of definite proportion?
The law of definite proportions was proposed by the French chemist Joseph Proust in the late 18th century. It states that a compound will always contain the same elements in the same proportion by mass, regardless of the amount of the compound.
Which type of substance is composed of two or more different kinds of elements always in the same ratio?
Two or more different elements that are chemically combined in a definite ratio is a compound. Based on the nature of the bonds, it can be called an ionic compound (i.e. atoms bonded together by ionic bonds) or an molecular compound (i.e. atoms bonded together by covalent bonds).
Why is the law of definite proportion important.?
In chemistry, the law of definite proportions, sometimes called Proust's Law, states that a chemical compound always contains exactly the same proportion of elements by mass. An equivalent statement is the law of constant composition, which states that all samples of a given chemical compound have the same elemental composition by mass. For example, oxygen makes up about 8/9 of the mass of any sample of pure water, while hydrogen makes up the remaining 1/9 of the mass. Along with the law of multiple proportions, the law of definite proportions forms the basis of stoichiometry.
When two or more elements combine chemically it is called?
When two or more elements combine chemically, it is called a chemical compound. In a chemical compound, the elements are bonded together in specific ratios to form a new substance with unique properties.
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.
What is made of two or more of something in exact proportions?
Physically, a mixture. Chemically, a compound.
What edvidence convinced Dalton that elements must be made of individual particles called atoms?
He deduced that from the law of definite proportions.
Substance made up of two or more elements is called?
A compound. A compound is a substance composed of two or more different elements chemically bonded together in fixed proportions.

What is the result called when elements are mixed chemically?
When elements are mixed chemically, the result is called a compound. A compound is a substance formed when two or more elements are chemically bonded together in a fixed ratio.
What is substance containing two or more elements chemically combined in a fixed ratio?
It is called a compound
What substance in which elements are chemically combined called?
Compound

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.

What is a group of elements that are chemically bonded called?
I believe it's called a compound.
