Some of the most common carbon compounds are: carbon dioxide (CO2), carbon monoxide (CO), carbon disulfide (CS2), chloroform (CHCl3), carbon tetrachloride (CCl4), methane (CH4), ethylene (C2H4), acetylene (C2H2), benzene (C6H6), ethyl alcohol (C2H5OH) and acetic acid (CH3COOH).

There are more carbon compounds than for any other element except hydrogen. The majority of these molecules are organic carbon compounds (e.g., benzene, sucrose), although a large number of inorganic carbon compounds also exist (e.g., carbon dioxide).

An organic compound must contain carbon and hydrogen. The four major categories of organic compounds that are present in all living things are carbohydrates, lipids, proteins and nucleic acid.

A compound is a unique substance that forms when two or more elements combine chemically. Compounds form as a result of chemical reactions. The elements in compounds are held together by chemical bonds.

On first glance, elements and compounds might appear different, yet they share many similarities, like being made up of atoms and having bonds linking their atoms together. Elements and compounds also share the qualities of being both pure and homogeneous substances.

Compounds are substances made from atoms of different elements joined by chemical bonds. They can only be separated by a chemical reaction. Common examples are water (H2O), salt (sodium chloride, NaCl), methane (CH4).

Potassium permanganate, also known as permanganate of potash or Condy’s crystals, is a chemical compound with a chemical formula of KMnO4, made of a potassium (K+) ion and a permanganate (MnO4-) ion. It is a strong oxidizing agent, so it readily takes or accepts electrons from other substances.

Pure substances can be either elements or compounds. Gasoline is thus a blend of different compounds, so it is a mixture.

Main compounds of milk are lactose and casein. And it is also called a colloidal mixture (i.e. in which one substance of microscopically dispersed insoluble or soluble particles is suspended throughout another substance). Therefore milk is regarded as a mixture not as a pure substance.

Milk is not a solution because it has more than one phase suspended in it — it has a liquid phase and a solid phase. Unhomogenized milk is not a solution, it’s a suspension because the fat (aka cream) will separate from the rest of the milk and rise to the top, since fat is less dense than water.

Mixtures. Vinegar is an example of a homogeneous mixture, and not a pure substance since water, its solute, is dissolved in the solvent, being acetic acid.

Only reagent grade elements could be called ‘pure’ or 100%. These would be used for analytical purposes or where other elements or compounds could contaminate a process. Cooking food does not require pure metal. Retail foil is apparently 92–99% pure.

Aluminum foil is made from an aluminum alloy which contains between 92 and 99 percent aluminum. Usually between 0.00017 and 0.0059 inches thick, foil is produced in many widths and strengths for literally hundreds of applications.

Since we know the composition of aluminum foil, which is basically Al, our response to the question is YES. That means it’s a SUBSTANCE. That means aluminum foil is an ELEMENT.

Dry ice is the solid form of carbon dioxide (CO2), a molecule consisting of a single carbon atom bonded to two oxygen atoms.

Dry ice, carbon dioxide in its solid form, a dense, snowlike substance that sublimes (passes directly into the vapour without melting) at −78.5 °C (−109.3 °F), used as a refrigerant, especially during shipping of perishable products such as meats or ice cream.

The quick answer is: Diamond is a pure element, carbon; gold is a pure element, gold; and rust is a compound, Iron Oxide, of iron and Oxygen. Diamond is pure elemental carbon, compressed to its crystal form, under extreme heat and pressure deep within the Earth.

The diamond is LIGHT, life, the SUN; it is an emblem of purity and perfection, of invincible spiritual power, and it is the stone of committment, faithfulness, and promise between husband and wife. Symbol of light and brilliance; unconquerable; treasures, riches, intellectual knowledge.

Elements and compounds are the two types of pure substances.

Air is considered as a mixture because of the following reasons: > It is possible to separate air into its constituent gases by means of physical methods like fractional distillation. The boiling point of nitrogen (77.3 K) is less than that of oxygen (90 K). This is the property of a mixture.

The two components of a solution are the solvent and the solute.
