When ##"H"_2"SO"_4"## reacts with sodium hydrogen carbonate there is no reaction at all. What is the chemical equation for this?

There is a reaction between sulfuric acid and sodium bicarbonate (also called sodium hydrogen carbonate and baking soda). This reaction produces sodium sulfate, carbon dioxide, and water. The general equation for this reaction is:

acid + carbonate ##rarr## salt + carbon dioxide + water

The balanced chemical equation for this reaction is:

##"H"_2"SO"_4("aq")## + ##"2NaHCO"_3"(aq")"## ##rarr## ##"Na"_2"SO"_4("aq")## + ##"2CO"_2("g")## + ##"2H"_2"O"("l")##
