  what can we see? and what are the reactions?

Can you try to write the ingredients as a chemical reaction, and see what the possible products are, or maybe why there wouldn't be a reaction.

well i guess it shud be like
Na2CO3 + Co2 + H20 ----> 2NaHCO3

but im not sure....

I am rewriting your formula using the feature of this forum that allow subscripts and superscripts and special characters like arrows.
Also be careful with capital and small letters your Carbon dioxide looked like Cobalt according to the way you typed it.

Na₂CO₃ + CO₂ + H₂O 2NaHCO₃

By the way there are WIKI articles that may be of interest for this question
http://en.wikipedia.org/wiki/Sodium_bicarbonate
http://en.wikipedia.org/wiki/Sodium_carbonate

As a side note

I searched thru yahoo answers too but I couldn't get a satisfactory answer but I was able to ask from one of my chemistry teachers. He said that there is an equilibrium this way.
Na₂CO₃ + CO₂ + H₂O  2NaHCO₃

Did you read this paragraph
http://en.wikipedia.org/wiki/Sodium_bicarbonate#Production

Also from the WIKI

Sodium carbonate
Solubility in water    
71 g/L (0 °C)
215 g/L (20 °C)
455 g/L (100 °C)[1]

Sodium bicarbonate
Solubility in water
69 g/L (0 °C)[2]
96 g/L (20 °C)[3]
236 g/L (100 °C)[2]

Do you think that might influence the reversibility of the reaction
Let us assume room temperature
 
By the way good job at using the subscript and arrows

[yasas.w]

Oh thank you 

Well I guess because of the solubility of Na₂CO₃ in room temperature, for sure it has a considerable effect on the forward reaction.

[Borek]

Na₂CO₃ + CO₂ + H₂O  2NaHCO₃

Details will depend on the initial concentration of carbonate, CO₂ pressure and temperature, but the reaction as written is exactly what will be responsible for any effects visible.
