carbon is very valuable as most of the compounds in nature (including human body) contains carbon
Carbon credits and the Renminbi. The Carbon credit is far more valuable though.
they are used for radio carbon dating....and carbon 14
Anthracite is the highest carbon coal, and therefore the most valuable.
Diamond is considered the most valuable form of carbon due to its exceptional hardness, brilliance, and clarity. Its rarity and desirability as a gemstone contribute to its high value in the market.
One form of carbon, such as diamonds, can be more valuable due to its rarity, hardness, and optical properties. The unique characteristics of diamonds make them desirable for use in jewelry and industrial applications, driving up their value compared to other forms of carbon like graphite or coal.
Deforestation is a serious problem for the world. It removes valuable trees that absorb carbon dioxide from the air and store the carbon. This extra carbon dioxide in the atmosphere is one of the reasons we have global warming.
A hydrocracker is a high-pressure, high-temperature catalytic reactor that uses hydrogen in the presence of a catalyst to break down heavy hydrocarbon molecules into lighter and more valuable products like gasoline and diesel. The process involves breaking carbon-carbon bonds and saturating carbon-carbon double bonds with hydrogen, resulting in improved fuel quality and increased yield of valuable products.
Probably the diamond, which is pure Carbon. I don't know offhand if its the only single element gemstone.
An extremely thin coating of carbon on rock is called carbon film. It forms when organic matter decomposes and leaves behind a thin layer of carbon on the surface of the rock. Carbon films are often preserved in fossils and can provide valuable information about the ancient environment.
No, carbon is not an ore. Ores are naturally occurring rocks or minerals from which a valuable substance can be extracted, whereas carbon is a chemical element commonly found in the Earth's crust and atmosphere.
The chief isotopes, carbon-12 and carbon-13, are not. However, carbon-14, a heavier isotope, is unstable and slowly decays, with a half-life of 5730 years. This makes it valuable to determine the age of fossils, by measuring their C-14 content.
The Carbon-Oxygen cycle is valuable to the biotic community because it helps regulate the levels of carbon and oxygen in the atmosphere, which are essential for the survival of many organisms. Plants take in carbon dioxide during photosynthesis and release oxygen, while animals and microorganisms release carbon dioxide during respiration. This cycle maintains the balance of gases necessary for life on Earth.
