Are elements that make up a compound always present in the same proportions?
No, elements in a compound are not always present in the same proportions. The ratio of elements in a compound is determined by its chemical formula.
John Dalton observed that elments always combine in the same ratio to form a particular?
compound. This led to the development of the Law of Multiple Proportions, which states that when elements form different compounds, the ratios of the masses of one element that combine with a fixed mass of the other element can be expressed in simple whole numbers.
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 always true of a binary compound?
A binary compound always contains two different elements. This means it will have a chemical formula consisting of two elements in fixed proportions. Binary compounds typically involve a metal and a nonmetal.
When two or more different atom combine together in a fixed ratio they produce?
a compound. Compounds are formed when two or more different elements chemically bond together in a specific ratio, creating a new substance with unique properties. The combination of atoms in compounds follows the law of definite proportions, meaning the ratio of elements in the compound is always the same.
Who proposed the theory that the elements in a compound always combine in the same fixed ratio?
Dalton
Who proposed the theory that elements in a compound always combine in the same fixed ratio?
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.
Which best describes john Dalton's observations of elements in any given compound?
Dalton discovered that the atoms that combine to form compounds are distinguished from one another by their atomic weights. He also learned that all atoms of a given element are identical.
Are elements that make up a compound always present in the same proportions?
No, elements in a compound are not always present in the same proportions. The ratio of elements in a compound is determined by its chemical formula.
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.
A given compound is always made of the same elements in the same?
A given compound is always made of the same elements in the same proportion.
Who determined that an element in a compound will always combine in the same whole number ratios?
Prous proposed this. he didn't prove it for all elements.His opponent was Berthollet who said he was wrongWe now know that the vast majority of compounds contain fixed whole number ratios of elements, but there are a few cases where there is some variability.
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.
John Dalton observed that elments always combine in the same ratio to form a particular?
compound. This led to the development of the Law of Multiple Proportions, which states that when elements form different compounds, the ratios of the masses of one element that combine with a fixed mass of the other element can be expressed in simple whole numbers.
Are Compound and elements always solid?
No, compounds and elements are not always solids. For example, hydrogen is a gas.
What are the masses of elements in a compound always in?
a cmpound
