What is meant by law of constant proportion and how is this law applied in experiment empirical formula of a compound?
The law of constant proportion states that a pure chemical compound always contains exactly the same proportion of elements by mass.This information, together with the atomic masses of the elements in the compound enable scientists to determine the formula of a compound.
What is the law of proportions?
A chemical compound always contains exactly the same proportion of elements by mass. ---------------------------------------------------------------------------------------------------- A law that states that a compound always contains the same elements in the same proportions. Source: e2020
Is h2 so4 a binary ionic compound?
No. Bianry compounds contain exactly two elements, an example is NaCl. H2SO4 has three elements and is a ternary compound.
Is calcium sulfate binary compound?
No. Calcium sulfate contains 3 elements (calcium, sulfur, and oxygen). A binary compound contains exactly two elements.
What is the law of definite proportions?

What is the relationship between atoms elements compounds and mixtures explain?
- The atom is representative for a chemical element (more exactly for an isotope); elements are formed from atoms. - A chemical compound contain two or more chemical elements. - A mixture contain two or more compounds.
A binary ionic compound is made of two components Name one of them?
A binary compound will contain atoms of only two elements. If the binary compound only contains nonmetal elements its name will begin with the prefix tetra.
Do compounds always contain the same elements in the ratio?
Yes because no samples are exactly the same.
The statement that a chemical compound always contains the same elements in exactly the same proportions is called the law of?
"In chemistry, the law of definite proportions and also the elements, sometimes called Proust's Law, states that a chemical compoundChemical_compoundalways contains exactly the same proportion of elementsChemical_elementby 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." - Wikipedia
Is 02- a binary compound?
A binary compound is a chemical compound that contains exactly two different elements. O2 has one, so its not a binary compound.
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:
Is cytoplasm a compound?
cytoplasm is a mixture because it is not exactly made of elements straight.....like a compound would.....
