Because silicon is a metalloid/semi-metal and carbon is a nonmetal, the bond is covalent.
A single carbon can make four bonds but they may not all be single i.e it could make 4 single bonds (as in methane) or 2 double bonds (as in cardon dioxide) or one triple bond and a single bond (as in Ethyne).
A plant cell.
It makes a covalent bond. This means a bond between a metal and non-metal element.
Respiration - make carbon in carbon dioxide
Roots do not make carbon dioxide.
solar
carbon dioxide
carbon dioxide :p
Plants don't make carbon dioxide.
Two oxygen atoms hooking up with a lone carbon atom equals......carbon dioxide!!To be truthful, Oxygen is usually found as a diatomic element (O2), so when it goes though bonding with a non-metal (such as carbon), it becomes carbon dioxide, the di- indicating that in this covalent bond, there are two oxygen atoms. Nitrogen Dioxide forms in the same manner.
For the applications of carbon monoxide see the link below. Carbon Dioxide is taken in by green plants and used to make Oxygen that we breathe. Carbon Dioxide is used to make 'Carbonated' beverages. Carbon Dioxide is used in many industrial applications, such as welding. Carbon Dioxide is used to make Dry Ice. Carbon Dioxide is used in Fire Extinguishers.
