Here we go.
Balance Sulfuric Acid + Sodium Carbonate in symbol equations
I got the following

H2SO4 + Na2 Co3 --> NaS + H2O +CO2

I am told that I need a salt, water (h2o) and Co2 as the products. I think my Salt is incorrect.

How do I go about balancing acid base reactions

[Hijacker]

I just realise this is a Acid- Carbonate reaction

Hint: You must have the same overall number of elements on both sides.

2xH 1xS 1xC 2XNa 7xO = 2xH 1xS 1xC 1xNa 3xO

Acid + Metal carbonate --> Carbon dioxide + Water + Metal Salt (from acid, either chloride, nitrate, etc... )

Hope it helped!:)
