This follows from the law of constant proportions which was discovered by the French chemist Joseph Proust. His law states that a chemical compound always contains the same elements combined together in the same proportion by mass.
Because that's the definition of a compound. Two substances are considered distinct if they have distinct compositions.
Today this affirmation is only partially valid; many nonstoichiometric compounds are known.
It shows the composition and the ratio of each element to one another within the compound.
A pure substance is composed of only one type of compound. Pure substances have a fixed composition and distinct chemical properties.
Prefixes in the name of a binary molecular compound indicate the number of atoms of each element present in the compound. The prefixes specify the quantity of each element in the compound, such as mono- for one, di- for two, tri- for three, and so on.
compound, expressed as a percentage. It can be calculated by dividing the molar mass of the element in the compound by the molar mass of the compound overall and multiplying by 100. This helps in determining the amount of each element present in a compound.
A mineral is defined as a compound having a fixed chemical composition ... Thus an element is not a mineral.
the composition varies from one compound to another
It shows the composition and the ratio of each element to one another within the compound.
the composition varies from one compound to another
It means that you have one atom of each element in the formula
there is only one atom of each element
A mineral is defined as a compound having a fixed chemical composition ... Thus an element is not a mineral.
This means that each molecule or formula unit of the compound contains only one atom of each element in the compound.
A pure compound is made up entirely of one substance that has a single chemical property. A mixture is made up of two or more pure compounds with distinct chemical properties.
Evaporites typically consist of minerals such as halite (rock salt), gypsum, anhydrite, and various carbonates like calcite and dolomite. These minerals are formed through the evaporation of water from an isolated body of water, leaving behind the dissolved salts and minerals.
To create a musical composition with a violin, only one string is ultimately necessary. You can create enough sounds with one string that you can create a composition with only one.
A homogenous compound is defined as that substance that only contains one kind of element or a compound. A homogeneous compound can be separated into its constituent components by physical means.
If it is a pure substance, than only one! Now that pure substance may contain many different elements (as many elements can make up a single pure compound), but a pure substance means only one compound.
