Compounds containing the carbon atom are called "organic" compounds. The term "organic" is used because at one time it was believed that carbon occurred only in living matter.
Wood isn't an element because it contains different types of atoms. It is a substance made of all sorts of various elements, such as carbon, hydrogen, oxygen and nitrogen. These elements form compounds, which are then built up to make materials such as wood.
They are built of complex hydrocarbons and trace minerals, and contain water, all of which are chemical compounds (of elements). They also need oxygen - itself an element.
there are 4 elements on a state people, territory, sovereignoity and government :)
Carbon dioxide and water
All of them since they are organic. Lipids, proteins, carbohydrates and nucleic acids are considered to be the 4 groups of biological macromolecules.
Carbon!

When it says 'life is carbon-based', it literally means just that. All forms of life are built off of the element Carbon, which is number 6 on the periodic table. All life is built off of carbon. Nothing can be considered life unless it has traces of carbon. For example, DNA is the base of human life, and carbon makes up most of the DNA, so when it says 'life is carbon-based', it means that all life depends on the element carbon, nicknamed 'the element of life'.
Chlorine is the element and CFC is the compound. They are built as refrigerating compounds. These compounds are used in AC's, Deodorants etc.The compound causing ozone depletion is CFC. They are chemicals of Fluorine. They form oxides with ozone.CFCs (chlorofluorocarbons).

Molecular compounds are built upon molecules that consist of more than one element such as water (H2O) or carbon dioxide (CO2). The common properties are low melting and boiling points, poor electrical and thermal conductivity, soft or brittle solid forms and low enthalpies of fusion and vaporization.
Carbon is an element and the definition of an element is that it cannot be broken down into any other element using chemical means. through fusion and fission it could be broken down or built up into oxygen or nitrogen or any number of other elements. But not without unearthly large amounts of energy (usually from a supercollider)
There are NO compounds IN CaCO3 and Mg(OH)2, they are two different compounds by themselves. Each compound is built up of two ore more differentelements, so in CaCO3 are calcium, carbon and oxygen (3x) and in Mg(OH)2 are magnesium (1x), oxygen and hydrogen (both 2x).
The phenomena of formation of large carbon compounds by the addition of small molecules is called polymerization and the molecules are come under macromolecules as they possess molecular weight several to hundred thousands

The strength of an item is just as much about its design as it is about the material, so there's no way to tell. A poorly built alloy fork, will be weaker than a well built carbon fork as well as the other way around.
Organic molecules are substances found in living things, the four main classes are carbohydrates, proteins, lipids, and nucleic acids.The original definition of organic chemicals were ones that could only be made by living things (organisms, thus the name) never in a lab. Then chemists gradually learned how to make a few of them. The definition was changed to complicated compounds containing the element carbon. This usually requires a minimum of 2 carbon atoms per molecule. Now we can make many of them in industrial quantities. An organic molecule are built around chains of carbon atoms and are the molecules of life. The four main groups of organic molecules are proteins, nucleic acids, lipids, and carbohydrates.
