Is water considered a mixture or a pure substance?
Water is a pure substance as much as pure Oxygen is pure oxygen. If you have air dissolved in the water, it is indeed a mixture or if you have salt dissolved, it is then a solution. Pure degassed water is a pure substance. Find, evaluate and source engineering materials online.
Why is water considered a compound?
Water is considered a compound because it is made of two elements hydrogen and oxygen combined in the ratio 1:8 by mass. Components of water cannot be separated by physical methods but can be separated by electrolysis of water. Why water is a compound Give 3 reasons? all compound are molecules but not all molecules are compounds.
Is water a compound or a molecule or both?
Thus, water is a compound. It's also a molecule, which is any chemical species formed by two or more atoms chemically bonded to each other. The terms "molecule" and "compound" mean the same thing and can be used interchangeably. Sometimes confusion arises because the definitions of molecule and compound haven't always been so clear-cut.
How is water a molecule and a compound?
Some examples of molecules include:
- Water: H 2 O
- Oxygen: O 2
- Ozone: O 3
Is water a mixture?
Water is a substance; more specifically, because water is composed of hydrogen and oxygen, it is a compound.

Is water a pure or mixture?
compoundWater, H2O, is a pure substance, a compound made of hydrogen and oxygen. Although water is the most abundant substance on earth, it is rarely found naturally in its pure form. Most of the time, pure water has to be created. Pure water is called distilled water or deionized water.
Why is water a compound?
Water is a compound because: It cannot be separated into its constituent elements by physical methods. The property of water is completely different from its constituent elements hydrogen and oxygen.
What is water mixed with?
Water is often found to be mixed up with minerals, salts, or other substances which have dissolved into the liquid.
What is a mixture?
Next, let’s talk about what a mixture is. A mixture is a material that is formed by more than one substance. Those substances are not chemically bonded together, and they can easily be separated. The usually retain their original characteristics.
Is Tap Water a Mixture?
Yes, tap water is a mixture. Unless your tap water source, pipes, and all the other transportation of the water from its source to where it is sampled is completely and totally free of substances that dissolve into the water, the water will contain other substances.
Is Water a Compound?
Yes, pure water is a compound. However, pure water rarely exists on Earth. As a result, if the water contains any ‘extras,’ it will be considered a mixture.
How is water made?
A compound is formed when two or more elements come together and bond to each other chemically. Water is formed when two hydrogens connect up with one oxygen, forming H2O.
Is pure water a mixture or compound?
So theoretically, pure water is just a compound and not a mixture.
Is distilled water pure water?
That being said, it is really unlikely that distille d water, even with an attempt to remove impurities, is completely and totally “pure” water.
What are the characteristics of water?
Though water is everywhere on Earth, it is a very unusual compound because of the nature of the chemical bonds between its atoms. Here are a few of its eccentricities: 1 Water is denser in its liquid state than in its solid state, which is why ice can float on or in liquid water. 2 Water has an unusually high boiling point based on its molecular weight. 3 Water is often referred to as the "universal solvent" because of its amazing ability to dissolve so many substances.
Why is water considered a universal solvent?
Water is often referred to as the "universal solvent" because of its amazing ability to dissolve so many substances. These unusual properties have had a profound impact on the development of life on Earth and on the weathering and erosion of Earth's surface.
What are some examples of compounds?
An example of a compound would be table salt, NaCl. However, as scientists came to understand chemical bonding better, the line between ionic and covalent bonds became fuzzier. Also, some molecules contain both ionic and covalent bonds between the various atoms. In summary, the modern definition of a compound is a type of molecule consisting ...
Why is water so unusual?
Though water is everywhere on Earth, it is a very unusual compound because of the nature of the chemical bonds between its atoms. Here are a few of its eccentricities: Water is denser in its liquid state than in its solid state, which is why ice can float on or in liquid water. Water has an unusually high boiling point based on its molecular weight.
Is a compound the same as a molecule?
It's also a molecule, which is any chemical species formed by two or more atoms chemically bonded to each other. The terms "molecule" and "compound" mean the same thing and can be used interchangeably. Sometimes confusion arises because the definitions of molecule and compound haven't always been so clear-cut.
Is water an element?
Before mankind knew about atoms and molecules, water was considered an element. Other elements included earth, air, fire, and sometimes metal, wood, or spirit. In some traditional sense, you could consider water an element, but it doesn't qualify as an element according to the scientific definition—an element is a substance consisting ...
Is water a chemical compound?
It would be logical to think that water must be one of the basic elements. But in reality, water is a chemical compound.
What is the chemical composition of water?
The chemical composition of water is H20 .
What is a compound?
Compound- A compound is a substance formed when two or more chemical elements are chemically bonded together. ... The type of bonds holding elements together in a compound can vary: two common types are covalent bonds and ionic bonds. The elements in any compound are always present in fixed ratios.
What is the symbol for water?
Two or more elements can combine to form a compound.And water is the compound having symbol H2O and it containing a elements hydrogen and oxygen.so,it called to be a compound.
What is diamond made of?
Diamonds are an allotrope of carbon, as is coal. An "Allotrope" implies a different bonding structure in coal than is in diamond. Carbon is the element common to both. Many people think of diamonds as coal that was compressed over millions of years and tonnes of pressure generated from the earth's repeated deposits of layers of soil and sediment onto layers deposited previously over vast periods of time.Mines run deep into the earth: in some places mines cut miles below the surface of the earth at a given location. Inclusions in diamond material are often small particles of carbon almost invisible to the naked eye but easily seen under 10x magnification- or with a jeweller's loupe ( graded diamonds are based on the quality or clarity of the diamond material as well as colour, and cut if it is a faceted stone used most commonly in jewellery). The more included a diamond is - or the higher the number of particles of carbon it contains- the lower its value.
What is a mixture characterised by?
Mixtures are characterised by being able to separate the components.

Is Water A Homogeneous mixture?
- While water as a whole is not a homogeneous mixture, smaller samples of water could be. It really depends on what the water contains, and the physical characteristics of those substances. A homogeneous mixture is a mixture that has a consistent composition throughout. You could take samples from one end of a pool and then the other, and get results showing that the chemical c…
