What law states that if two or more compounds are made up of the same two elements the ratio of the masses of the second element is always a ratio of small whole numbers?

In a molecule there will always be integer numbers of a certain atom, and you can never have 3.5 oxygen atoms or 2.493 chlorine atoms in a compound. Atoms are singular units of molecules. Therefore a ratio of integers is always present for all types of atoms in a molecule.

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.
What Compounds contain carbon element?
There are plenty of compounds that do: ethanol-AKA Jack Daniels/beer/vodka rubbing alcohol sugar proteins carbohydrates fats
What is the difference between inorganic compounds and organic compounds?
In general, organic compounds are those compounds which contain both carbon and oxygen, and inorganic compounds lack these atoms. Of couse, this does not always apply, as carbon dioxide and carbon monoxide also contain both these elements and are still labeled as inorganic.
Substance in which all atoms are alike?
A substance in which all atoms are identical is called an element.
Can you always determine an element by the number of neutrons?
No, because some elements have Isotopes, with the same Proton number but different Neutron numbers. Sometimes therefore, the neutron number can overlap with that of isotopes of other elements. For example, two of Helium's isotopes share neutron numbers with two of Hydrogen's isotopes. Deuterium has 1 neutron, and so does 3He, Tritium has 2 neutrons, and so does 4He. It is the number of protons which determines which element it is.
Are elements denser than compounds?
Elements are often denser than compounds, but not always. In fact the least dense substance known is hydrogen, which is an element.
What element do organic compounds always contain?
Organic compounds always contain the element carbon.
What is the answer to oxides are compounds that always have the element in them?
Oxygen.
Are compounds always the same as their elements?
Not necessarily
Are Compound and elements always solid?
No, compounds and elements are not always solids. For example, hydrogen is a gas.
What do compounds always contain exact ratios of?
elements
What element do all inorganic compounds lack?
There is no element that is always found in inorganic compounds. However, organic compounds always contain carbon and hydrogen, so they would not be found together in an inorganic compound.
What two elements organic compounds always contain?
Organic compounds always contain Carbon and Hydrogen. Most organic compounds contain elements like Oxygen,Nitrogen,Phosphorus and sulphur. Organic compounds are found in living things.

Is a mixture always made up of a combinations of elements?
rtyuikl
Organic compounds always have what two elements in them?
carbon and hydrogen
When elements that are never found free in nature but are always found combined in a compound are the?
Any element that's not a noble gas has to form compounds, because all non-noble elements have to fill its outer orbital and the only way they can do that is to form compounds--even with themselves, like H2 or O2.
