diamonds are also formed by carbon, but is carbon available at 200 kms below the earth's crust? or are there other gases that make up carbon, and through which carbon is made? carbon is formed by living organisms and a diamond is formed by carbon, so a diamond should be organic, but...
Mark Patel:The concept of carbon dioxide removal is, if we can’t entirely cut out the activities that are causing emissions, then let’s instead find other mechanisms in which we can remove carbon dioxide, or gases that are equivalent to carbon dioxide. We use the term “carb...

compound In chemistry, a compound is a substance made up of two or more different chemicalelementscombined in a fixed ratio. When the elements come together, they react with each other and form chemical bonds that are difficult to break. These bonds form as a result of sharing or exchanging...
(including coal, petroleum, and natural gas) and is released as the harmful toxin carbon dioxide (CO2) when this kind of fuel is burned. CO2is the compound primarily responsible for the "greenhouse" effect of trapping heat within the Earth's atmosphere, and is thus one of the primary ...
(although not agreed upon). An organic compound must contain at least carbon. Most chemists agree hydrogen must also be present. Even so, the classification of some compounds is disputed. Major classes of organic compounds include (but are not limited to)carbohydrates,lipids,proteins, andnucleic ...
