Who said that a given compound always contains the same elements in the same proportions by mass?
This statement was made by French chemist Joseph Proust and is known as the Law of Definite Proportions. It states that a compound always contains the same elements in the same proportions by mass regardless of the source of the compound.
Are all elements made up of different elements combined?
No, each element is in basic form and are always only made up from themselves. When elements are combined this is a compound.
Is a compound made up od at least 3 elements?
a compound can be made out of 2 or more elements
Which describes john daltons observation of elements in any given compound?
One of the best ways to describe John Dalton's observations of elements is that they are made of small particles. The atoms join in simple whole number ratios when the elements react.
What is a compound substances?
A compound substance is one that is made up of two or more elements.
What is different between element amd compound?
A compound is made up of two or more elements (water is a compound, made up of two elements: oxygen and hydrogen).
Who developed the law of definite composition?
In chemistry, the law of definite proportions and also the elements, 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.This observation was first made by the French chemist Joseph Proust based on several experiments conducted between 1798 and 1804. Based on such observations, Proust made statements like this one, in 1806:
What is the relationship between a compound and the elements from which it is made?
A compound is made up of two or more elements that are chemically bonded together. The elements in a compound are combined in specific ratios to form a new substance with unique properties different from the individual elements.
Do compounds always contain the same elements in the ratio?
No, compounds do not always contain the same elements in the same ratio. Compounds are formed by the combination of two or more elements in fixed proportions by mass. The ratio of elements in a compound is determined by the chemical formula of the compound.
Is metal a compound?
No, a compound is something made out of two or more elements.
Is magnesium compound or element?
it is a compound as it is made up of two elements
Is a molecule a form of compound?
A compound is a substance made up of elements that have combined; a molecule is the smallest unit of which the compound is made.
