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
What are the drawbacks of law of constant composition?
kill kill king king
The first chemist to formally state the law of constant composition was?
Proust
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.
Evidence that supports the law of constant composition?
A piece of evidence that is commonly used to prove the law of constant composition is that any sample of water is 88. 71 percent oxygen and 11. 19 percent hydrogen. It was formulated by Joseph Proust.
What would Proust say about the composition of all carbon dioxide molecules?
He would insist that all Carbon Dioxide molecules have the same composition, by his Law of Constant Composition.
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.
What data does a sample of pure water irrespective of its source contains 11.1 hydrogen and 88.9 oxygen support?
It might have supported Proust's law or the law of definite composition, or law of constant composition. But unfortunately the data used are not accurate. The correct proportions, based on relative atomic masses of hydrogen and oxygen being 1.008 and 15.999 give the results as 11.2% and 88.8%.
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.
Why is the law of definite composition important?
Think of it in terms of a scientist performing a lab experiment. He/she will need to know the specific amounts of substance required to obtain the desired reaction. The law is fundamental for stoichiometry operations.
