Minerals are Substance composed of two or more elements bonded together in definite proportions?

Substances composed of two or more elements bonded together in definite proportions are chemical compounds by definition. This is not a correct definition for minerals, because some of them are mixtures of more than one compound, and some minerals, such as gold and diamond, are elements instead of compounds.

But some minerals contain only one element: diamond, graphite, gold, Mercury, etc.

Is a compound a substance of two or more elements bounded together in definite proportions?
A compound is a substance of two or more elements bounded together in definite atomical proportions
What do Chemical composition describes?
"chemical composition" is talking about the individual chemicals that make up a substance. The chemicals it is composed of. eg, wood is mainly carbon, with some water (which is hydrogen and oxygen) and various minerals.
Can the proportions of magnesium and oxygen in magnesium oxide be changed?
No. Magnesium oxide, MgO, is a compound, which means it is a pure substance, in which the magnesium and oxygen are present in definite proportions, in this case 1:1. This is in accordance to the law of definite proportions, which states that every pure substance always contains the same elements combined in the same proportions by weight. Also, magnesium ions have a charge of 2+ and oxide ions have a charge of 2-, so that one magnesium ion combined with one oxide ion balances to an overall charge of zero.
Why is a sample of matter considered a pure substance?
A pure substance is either an element or compound. Elements are composed of only one kind of atom, and compounds are composed of a definite proportion of atoms of different elements that is always the same.
When geologist say that a mineral always contains certain elements in the definite proportions they mean that the mineral has a definite?
A chemical formula.
Is a compound a substance of two or more elements bounded together in definite proportions?
A compound is a substance of two or more elements bounded together in definite atomical proportions
How are compounds diffident from mixtures?
Compounds are composed of atoms of different elements chemically bonded in definite proportions. The components of mixtures are not chemically combined and they do not have definite proportions.
Why is water not a compound?
Water most definitely IS a compound! It is a compound composed of hydrogen and oxygen atoms chemically bonded in a definite proportion of 2H:1O. The molecular formula is H2O. A compound is a pure substance composed of different elements chemically bonded in definite proportions.
What do Chemical composition describes?
"chemical composition" is talking about the individual chemicals that make up a substance. The chemicals it is composed of. eg, wood is mainly carbon, with some water (which is hydrogen and oxygen) and various minerals.
What factors affect the ratio when substance combine to form compounds?
These are the laws of multiple proportions, definite proportions and mass conservation.
What are pure compounds?
A substance made from two or more elements in definite proportions. eg NaCl
What term describes a substance formed by the combination of two ore more elements in definite proportions?
Compound
When was the law of definite proportions developed?
The law of definite proportions was developed by Joseph Proust in 1806.
What is the law that states that a chemical compound always contains the same elements in exactly the same proportions by w eight and mass?
Law of definite proportion, sometimes also called the law of constant composition.
Which of Dalton's four principles support law of definite proportions?
Dalton\'s principle of compounds supports the law of definite proportions.
State the law of definite proportions?
The law of definite proportions states that all chemical compounds have constant proportions of their components.
What is fixed composition?
Today the laws of definite proportions and multiple proportions, applied to chemical compounds, are considered as not genarally valid.Many mixtures (not all !) have a fixed composition depending on the specific application and recipe.
