Compounds are substances that can be broken down through various chemical processes into elements. Elements are substances that cannot be broken down any further; all the atoms of an element are identical. However, a compound contains at least two different kinds of elements. Combinations of the various elements creates compounds. Different ratios of those same elements creates different compounds.
Water, being composed of the elements hydrogen and oxygen, is therefore a compound, as is carbon dioxide, which is composed of the elements carbon and oxygen. Ammonia, composed of the elements nitrogen and hydrogen, is also a compound. Adding an additional atom of oxygen to a water molecule creates a new compound -- although it still just contains hydrogen and oxygen, like water (H2O), it has two atoms of each. This is the compound hydrogen peroxide (H2O2).
Compounds are substances that have molecules containing atoms of more than one elements. Compounds are formed by chemical combination of elements.
Perhaps the most common compound we know is water, which has the chemical formula H2O. water is formed when hydrogen gas reacts chemically with oxygen. Each molecule of water contains two atoms of hydrogen and one atom of oxygen. Some other common compounds include the following:
- Carbon dioxide gas (CO2) formed by combination of carbon and oxygen. Human beings absorb oxygen from the air they breathe, which combines with carbon present in the food in the body to produce energy. During this process carbon dioxide is produces which is released with the air we breathe out.
- Common salt (NaCl), which has the chemical name of sodium chloride and is composed of sodium and chlorine.
- Alcohol (C6H5OH) is an organic compound composed of carbon, hydrogen and oxygen.
A compound, when we are talking about chemistry, is simply any substance that is made up of two or more elements which react with one another. The elements must be present in fixed ratios.
So water is an example of an element. In all pure water, there are two parts of hydrogen to one part of oxygen.
Similarly, carbon dioxide fits the criteria for being a compound. You have two elements -- carbon and oxygen that react to bond to one another. There is always two parts oxygen to one part carbon in this compound.
Compounds are pure chemical material that consists of two or more elements combined together. There are many compounds such as Aluminum nitride, Aluminum oxide, Aluminum chloride, Aluminum hydroxide, Aluminum nitrate, Chromium(III) chloride, Cerium(III) chloride, and Cacodylic acid.
Some of the more common compounds are table salt which is NaCl.
Soidium Nitrate is also known as Salt Peter and when combined with sugar makes smoke bombs. They are relatively safe to make but should be lit outside. To make them take 1 teaspoon of sugar and one teaspoon of Sodium Nitrate (found at a pharmacy and costs about ($8-$10). Take a frying pan and heat the two ingredients until they melt and look Carmel colored. Put onto tin foil in small clumps. Take outside and light.
Compound is a chemistry term, which refers to a pure substance that contains two or more elements chemically combined together during a chemical reaction. It must be in a fixed composition, and can be broken down by heat during thermal decomposition or by using electricity.
There are many types of compound, like carbon dioxide (carbon and oxygen), common salt (sodium, chlorine), marble ( calcium, carbon, oxygen), copper (II) sulphate (copper, sulphur, oxygen) and hydrogen chloride (chlorine and hydrogen).
Here's a example. Water (H2O) is a compound made by joing together two atoms of hydrogen to one atom of oxygen and the ratio between them is 2:1
Examples of compounds:
Baking Soda (NaHCO3)
Coumpounds is a substance made up of two or more elements that are combined! Example of a compund could be water (H2O), Carbon Dioxide (CO2) e.t.c.
Compound is made up of two or more elements. Examples include water.
Compound is made up more than 2 elements and compound can be broken up. Ex: H20(Water); NaCl(salt)
A compound is substances made up of 2 or more elements chemically combined like: Salt, water and Carbon dioxide
If you're looking into the chemistry definition of a compound, then, a compound is any equal ratio of two different substances reacting to each other. Some examples may include:
A compound in chemistry is when you have two or more elements that are bonded together .
Examples of compounds :
- H20 = water
- C6H12O6 = sugar
- NaCl = salt
- C2H6O = alcohol
- C4H10= butane
- NaHCO3 = baking soda
- N20 = nitrogen
- CH4 = methane
- C8H18 = Octane
Examples of some compound:
- Carbon Dioxide
NaCl = Salt
H20 = water
CO2 = Carbon dioxide.
If you are looking at compounds from the chemistry point of view/perspective, compounds are essentially just two or more different chemical elements combined to make one. Salts are a great example of a compound. Many different elements can make up a salt but here are a couple:
NaCl (You have sodium and chloride together)
KI (You have potassium and iodine together)
A compound is a result of 2 or more elements combined. An example would be Co2 for carbon dioxide -- a mixture of carbon and oxygen.
A chemical compound is a chemical substance that is made of two or more atoms of different elements that share a chemical bond. A chemical formula represents the ratio of atoms per element that make up the chemical compound. This is done via the use of subscripts. The subscript that lies to the right of the symbol for each element indicates the number of atoms of that element that make up that chemical compound.
Examples of chemical compounds are as follows:
- Water (H2O, consisting of 2 hydrogen atoms and one oxygen atom)
- Carbon dioxide (CO2, consisting of one carbon atom and two oxygen atoms)
- Sodium Chloride (NaCl, consisting of one sodium atom and one chloride atom)
- Methane (CH4, consisting of one carbon atom and four hydrogen atoms)
The second link provided below show a slue of other examples of chemical compounds.
A compound is made up of two or more elements.
some examples are
H2O - Water
NaCl - Salt
N20 - Nitrogen
