Is hydrogen oxygen and water an element compound or mixture?
Hydrogen and oxygen are both elements, but they also normally exist as molecules consisting of two atoms (H2 and O2). Because hydrogen forms bonds with oxygen to make water, water is a molecule. Water is also a compound.
What type of mixture is hydrogen and oxygen?
Oxyhydrogen is a mixture of hydrogen (H2) and oxygen (O2) gases. This gaseous mixture is used for torches to process refractory materials and was the first gaseous mixture used for welding.
Why are hydrogen and oxygen elements and water compound?
Answer : Hydrogen and oxygen are made up of same kind of atom hence these are considered as elements whereas water is made by the combination of different kinds of atoms such as hydrogen and oxygen, hence it is called as a compound and not an element.
What are the examples of element compound and mixture?
Chemistry: 12. Elements, Compounds and Mixtures
Compound | Symbol | Elements in the compound (and state at room temp) |
---|---|---|
Water | H2O | Hydrogen (gas) oxygen (gas) |
Carbon dioxide | CO2 | Carbon (solid) oxygen (gas) |
Magnesium oxide | MgO | Magnesium (solid) oxygen (gas) |
Iron sulphide | FeS | Iron (solid) Sulphur (solid) |
Is water mixture of hydrogen and oxygen?
Water is a chemical compound made up of hydrogen and oxygen combined in the ratio 2:1 by volume or 1:8 by mass (2 g of hydrogen combines with 16 g of oxygen).
Is hydrogen an elements compound or mixture?
Hydrogen, with the formula H2, is an element, not a compound. Compounds can be decomposed into their constituent elements. An example is water being chemically decomposed into its two elements, hydrogen and oxygen, by electrolysis: passing electricity though a water solution.
What mixture is water?
Water, 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.
Can you mix hydrogen and oxygen for water?
In theory, it’s easy to make water from hydrogen gas and oxygen gas. Mix the two gases together, add a spark or sufficient heat to provide the activation energy to start the reaction, and presto—instant water.
What is element water hydrogen and oxygen?
Hydrogen and oxygen are considered as elements which cannot split into different substances by applying any kind of energy like heat or electricity whereas water is a composed of constituents like hydrogen and oxygen in a fixed proportion and it can be split up by applying energy. So, it is not an element.
Is hydrogen an element compound or mixture?
Hence, hydrogen is an element made of an aggregate of hydrogen atoms while oxygen is an element made of oxygen atoms. However, water is a compound made of water molecules. Note that the molecules which form a compound are made of different types of atoms, but molecules can also consist of atoms of the same kind.
When hydrogen and oxygen combine to form water water would be?
When water is formed, a large amount of energy is released. This is a sign that the compound formed is highly stable. Therefore, when hydrogen and oxygen combine to form water, they form (D) an extremely stable compound.
