A chemical formula.
When geologists say that a mineral always contains certain elements in definite proportions, they mean that the mineral always has a specific chemical composition. This composition is a key characteristic that helps identify and classify minerals. Minerals are composed of specific elements arranged in a precise crystal lattice structure.
"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
This is a chemical compound.
A compound is a substance of two or more elements bounded together in definite atomical proportions
This is a chemical compound (a molecule).
Yes
yes, it is true!
The law of definite proportions states that a compound always contains the same elements in the same proportion by mass, regardless of the source of the compound. This means that for a given compound, the ratio of the masses of the elements is always constant.
The law you are referring to is the Law of Definite Proportions. This law states that a chemical compound always contains the same elements in the same proportions by mass, regardless of the source of the compound.
A mineral always contains certain elements in definite proportions
This statement was made by French chemist Joseph Proust and is known as the Law of Definite Proportions. It states that a compound always contains the same elements in the same proportions by mass regardless of the source of the compound.
Yes, minerals have a specific chemical composition, meaning they contain certain elements in definite proportions. This is a characteristic feature of minerals that distinguishes them from other natural substances.

No, a mineral does not always contain certain elements in definite proportions. While minerals have a specific chemical composition, the proportions of elements can vary within certain limits and still be considered the same mineral.
