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.
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.
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.
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.
Does evidence prove or disprove evolution?
Law and math prove things. Science supports tentative ( more or less ) explanations of natural phenomenon with evidence. The evidence overwhelmingly supports evolutionary theory. PS Evolution itself is a observed and observable fact.
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.
