What else can I help you with?
What is evidence that supports the law of constant composition?
The mass ratio of carbon to oxygen in carbon dioxide is always 3:8 In a molecule of water, the mass of oxygen is always 8 times the mass of hydrogen
If Law of constant composition true for all types of compounds?
No,Law of constant composition is valid only for compounds made from the specified isotopes of the element.
Does compound follow the law of constant composition?
because 789
Atoms of different elements combine in whole number what?
That is the law of constant composition.
What is meant by the law of constant composition for compounds?
The law of constant composition for compounds is a law in chemistry according to which any given compound always contains the same component elements in the same ratios, by mass. The ratios do not depend on where the compound comes from or the way in which it was produced.
Who stated the law of constant composition?
Joseph Louis Proust (1754-1826), In 1799 Proust stated that "Compounds always contain the same elements in a constant proportion by mass." This statement is now called law of definite composition or the law of constant proportion.
The first chemist to formally state the law of constant composition was?
Joseph Louis Proust.
What does law of constant composition applies to?
The law of constant composition applies to chemical compounds, stating that a compound is always made up of the same elements in the same proportion by mass. This means that the ratio of elements in a compound is fixed and does not change regardless of the source or method of preparation.
Which is supported by the law of constant composition?
In water, there is always 8 times the mass of oxygen than there is of hydrogen.
What are the drawbacks of law of constant composition?
One drawback of the law of constant composition is that it may not hold true for all substances, especially those with variable composition such as alloys or solid solutions. Additionally, it assumes that compounds are made up of discrete units, which may not always be the case at the molecular level. Finally, the law does not account for isotopic variations in elements.
Who was the scientist that helped prepare the way for daltons work by developing the law of constant composition?
The scientist who helped prepare the way for Dalton's work by developing the law of constant composition was Joseph Proust. Proust formulated this law, also known as the law of definite proportions, which states that a given compound always has the same elements in the same proportion by mass.
Why is the law of constant composition important to chemistry?
It means that in any pure compound, the proportion of constituent elements (by mass) is a constant. This allows their chemical formulae to be determined.
