- 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 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:

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
