The Vespiary

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

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

thanks for clarifying that with me. can you suggest any book on Math of Chemistry?

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

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  ;)  you might want this
