They list the elements in a molecule, numbers of each, and positive or negative charges.
Formulas for covalent compounds are called molecular formulas. They show the types and numbers of atoms in a molecule.
All chemical compounds will have a chemical formula. For instance, the calcium chloride has formula CaCl2. Elements, on the other hand, have chemical symbols. Chemical reactions can be represented by chemical equations.
the composition varies from one compound to another
Nonstoichiometric compounds have a variable composition.
Organic Compounds.
Prefixes in compound names are used to indicate the number of each element present, similar to how subscripts in chemical formulas specify the quantity of each element in a molecule. Both prefixes and subscripts help provide important information about the composition of compounds in a clear and concise manner.
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.
Assigning a symbol to represent each element allows for a more concise and universal way of referring to elements in the periodic table. It also simplifies chemical formulas and equations, making it easier to communicate and understand the composition of compounds.
Yes, all compounds are molecules, but not all molecules are compounds
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).
