It's black and it come out in a powder form
The physical description of carbon : It is black and it comes in a powder form A form of carbon is diamond.
oxygen and carbon dioxide
That's a reasonable description of a "hydrocarbon"
Molecules made of carbon and hydrogen are various and diffuse. The best description is that they are hydrocarbons and they burn well.
Glucose lose electrons and hydrogen to form Carbon dioxide.
A polymer would fit this description.
That sounds like a description of Venus.
Sounds like a description of amino acids.
The carbon-carbon bonds in ethene (C2H4) are classified as double bonds. This means that each carbon atom forms two covalent bonds with the other carbon atom, resulting in a strong and stable connection. Double bonds are characterized by the sharing of two pairs of electrons between the carbon atoms.
Compounds that contain carbon-hydrogen bonding are collectively termed organic compounds. These are simply compounds that would contain hydrogen and carbon elements.
Venus would be the terrestrial planet that fits that description, while Jupiter would be a gas giant that has similar properties.
No, it is not.Rain forests take in carbon dioxide from the atmosphere and release oxygen. Human and animal lungs do the exact opposite.
