The AP Chemistry Exam has one question that requires you to write balanced equations for chemical reactions. In all cases, a reaction occurs. Assume the solutions are aqueous unless otherwise indicated. Represent substances in solutions as ions if the substances are extensively ionized. Omit formulas for any ions or molecules that are unchanged by the reaction. You need not balance the equation.

The question clearly says equimolar, hence:
Na2CO3 + HCl -----> NaHCO3 + NaCl

HCl+NaCO3 -> NaCl + CO2 + H20 this is the chemical equation (no longer balanced). It shows that the two hydrogen atoms bond to an oxygen atom to make water, the sodium bonds to the chlorine to make sodium chloride which leaves the carbon and leftover oxygen to bond to make CO2. With lots of those reaction it incredibly is often: acid + steel carbonate -> a salt + water + carbon dioxide i'm hoping that I replied it in the variety you have been searching for
