This law is not valid for all chemical compounds (ex. nonstoichiometric compounds).
A compound has a definite composition, while a mixture's composition can vary.
No,Law of constant composition is valid only for compounds made from the specified isotopes of the element.
A poptart is a pastry, it is an artifact constructed of various compounds. It not only has a chemical composition, it has a structure as well. It fits in your toaster.
A pure substance is a material that is composed of only one type of particle or element. It has a definite and constant composition with uniform properties throughout. Examples include elements like gold or compounds like water.
Definite chemical composition is when a mineral is made of the same material throughout. Basically when a mineral is only made of one material all the way through, not part iron in one part and then gold in the rest.
Today this assertion is only partially valid; many nonstoichiometric compounds are known.
Only after experiments and determination of the chemical composition.
A pure substance is a substance that is made up of only one type of particle, either an element or a compound. It has a consistent and definite chemical composition and physical properties. Examples include elements like gold and compounds like water.
A substance that always has the same composition is called a pure substance. This means it is made up of only one type of atom or molecule, leading to consistent characteristics like melting point and boiling point. Examples of pure substances include elements like gold and compounds like water.
Elements and compounds are considered substances because they have distinct chemical properties and compositions. Elements are pure substances made up of only one type of atom, while compounds are composed of two or more different types of atoms chemically bonded together. Both elements and compounds have specific physical and chemical characteristics that distinguish them from mixtures.
Some examples of pure compounds include water (H2O), table salt (NaCl), sugar (C12H22O11), and carbon dioxide (CO2). These compounds consist of only one type of molecule and have a fixed chemical composition.
No, compounds do not always contain the same elements in the same ratio. Compounds are formed by the combination of two or more elements in fixed proportions by mass. The ratio of elements in a compound is determined by the chemical formula of the compound.
