       i know this is a really stupid question ,but ...     

Sorry , i know this a waste of peoples time.
but me and someone are in a little stupid argument.

someone said

NaOH + CO2 -> NaHCO3

i said

NaOH + CO2 -> NaCO2 + H2O

       Sodium Hydroxide + Carbon Dioxide => ?     

NaOH + CO2 -> NaCO2 + H2O

The above equation is incorrect, because:
  • There are two hydrogens on the right side and only one at the left side.
  • "NaCO2" is a non-existant compound.
However, the following equations are correct descriptions of reality:

NaOH + CO2 -> NaHCO3
NaOH + NaHCO3 -> Na2CO3 + H2O

Hence, the sum of those two equations gives this:

2 NaOH + CO2 -> Na2CO3 + H2O

       balancing chemical equations     

If you mean stoichiometry (i.e. balancing chemical equations), begin with with  and if you want other here are a few:

http://hmchemdemo.clt.binghamton.edu/zumdahl/docs/chemistry/03stoichiometry/library/0307.htm
http://www.chemistry.ohio-state.edu/betha/nealChemBal/
http://newtraditions.chem.wisc.edu/FPTS/fbeqns/chemeqnf.htm
http://dbhs.wvusd.k12.ca.us/webdocs/Equations/Balance-Equation.html

Also, if you search google.com for "balancing chemical equations" you will find 50+ pages with that as title.
There is no need to buy an actual book on the topic with so much free tutorials online.

Finally, if you want to cheat wink you might want this Shareware Equation Balancer (http://www.molecularsoft.com/balanceequation.htm)
