A compound is a pure chemical substance that consists of two or more different chemical elements. It contains a fixed ratio of atomsthat are held together in a defined spatial arrangement by chemical bonds.
The statement that all compounds have a composition of ionic compounds is false. Many compounds can be covalent in nature, where atoms share electrons instead of transferring them. On the other hand, it is true that compounds have a definite composition with fixed ratios of elements and compounds are formed by the bonding of two or more different elements.
Yes, compounds have a definite chemical composition. This means they are made up of a specific ratio of elements that are bonded together in a fixed arrangement. This composition can be represented by a chemical formula.
Coal tar is a complex mixture of organic compounds derived from the distillation of coal. It contains various hydrocarbons, phenolic compounds, and heterocyclic compounds. The specific composition of coal tar can vary depending on the source and method of production.
Crude oil consists of thousands of different compounds, including hydrocarbons, sulfur, nitrogen, and oxygen compounds. The exact number of compounds in crude oil can vary depending on its source and composition.
A chemist studies the composition, structure, properties, and changes of matter. They explore the elements, molecules, and compounds that make up substances and how they interact with each other.
the composition varies from one compound to another
Nonstoichiometric compounds have a variable composition.
The statement that all compounds have a composition of ionic compounds is false. Many compounds can be covalent in nature, where atoms share electrons instead of transferring them. On the other hand, it is true that compounds have a definite composition with fixed ratios of elements and compounds are formed by the bonding of two or more different elements.
No,Law of constant composition is valid only for compounds made from the specified isotopes of the element.
Compounds differ from mixtures because compounds have a fixed chemical composition with elements chemically bonded in a specific ratio, while mixtures can vary in composition with no fixed ratio. Compounds have specific properties different from their constituent elements, while mixtures retain the properties of their components.
This law is not valid for all chemical compounds (ex. nonstoichiometric compounds).
Yes, compounds have a definite chemical composition. This means they are made up of a specific ratio of elements that are bonded together in a fixed arrangement. This composition can be represented by a chemical formula.

No. A compound will always have the same composition.
Coal tar is a complex mixture of organic compounds derived from the distillation of coal. It contains various hydrocarbons, phenolic compounds, and heterocyclic compounds. The specific composition of coal tar can vary depending on the source and method of production.
The composition of an object refers to the materials it is made of. This includes the elements, compounds, or substances that form the object's structure and properties.
what are the composition of organic compounds? "Carbong, Hydrogen and oxygen with small amount of halogen, nitrogen, sulfur and phosphorus are the chief elements found in organic compounds." No, A composition of organic compounds are carbohydrates, lipids, proteins, nucleic acids. Source: In AP Biology.
