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.
What else can I help you with?
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
When geologists say that a mineral always contains certain elements in definite proportions they mean that the mineral always has what?
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.
Minerals are made in what definite proportion?
Minerals are made of specific chemical elements in fixed proportions, which gives them their unique composition and properties. These proportions are determined by the mineral's crystal structure and the way the atoms are arranged within it.
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.
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.
Is it true that a mineral always contains certain elements in definite proportions?
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.
When geologists say that a mineral always contains certain elements in definite proportions they mean that the mineral always has what?
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.
What are pure compounds?
A substance made from two or more elements in definite proportions. eg NaCl
Does a mineral always contain certain elements in definite proportions?
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.
Minerals are made in what definite proportion?
Minerals are made of specific chemical elements in fixed proportions, which gives them their unique composition and properties. These proportions are determined by the mineral's crystal structure and the way the atoms are arranged within it.

What term describes a substance formed by the combination of two ore more elements in definite proportions?
A compound is a substance formed by the combination of two or more elements in definite proportions. Each compound has a specific chemical formula that indicates the types of atoms present and the ratio in which they are combined.
When was the law of definite proportions developed?
The law of definite proportions was developed by Joseph Proust in 1806.
What is Substances composed of 2 or more elements chemically united in a definite proportion by mass?
A compound is a substance composed of two or more elements chemically bonded in a fixed ratio by mass. This means that compounds have a specific chemical formula that indicates the types and proportions of elements present in the compound.
