Svetach [21]
All life as we know it is carbon-based, so what scientists could determine is that there is no carbon-based life at the origin of the meteorite. However, this does not necessarily mean that there is no life there; our knowledge is only based on our experiences of life on Earth, so it is possible that life has developed in other regions of space upon other elements and formations.

Make a decision about the molecule NaHCO3 classification organic or inorganic
motikmotik

<u>Answer:</u>

NaHCO_{3} is an inorganic compound.

<u>Solution:</u>

  1. Firstly, all the known definitions of organic compounds excludes Carbonic acid and it's salt from organic compounds except if 'C' is present in the cation.  
  2. Secondly, Sodium is a metal which organic compounds cannot posses as a compound.  
  3. Lastly, there is absence of C-H bond which is present in all the organic compounds.

Hence, we can conclude that NaHCO_{3}is an inorganic compound though there is presence of Carbon atom in it.
