   The chemical properties of carbon compounds (and everything else) will   
   be the same as well. The physical properties (e.g., the state and   
   density) could vary depending on air pressure and temperature. I would   
   suspect that a "heavy" Earth (i.e., solid body 6-10 times Earth's mass)   
   could have lakes of liquid carbon dioxide.
