CARBON OXIDES
 Carbon Oxides CO and CO2
• combustion with oxygen in oxygen poor
condition forms carbon monoxide and in
oxygen rich conditions carbon dioxide.
2C(s) + O2(g) ® 2CO(g)    2C(s) + 2O2(g) ® 2CO2(g)
• the chemistry of carbon includes the notable ability to multiple-bond with
other elements.   :CºO:          O=C=O
• carbon monoxide is poisonous as it complexes readily with metals such as Fe;
it is widely used in metallurgy and heating.
• carbon dioxide is non-toxic and is used in
refrigeration, baking soda and Coke®.
