Well, the only equation that seems to fit is the one with the strarting products on the left-hand side of the equation.

When you're starting these types of problems first write down the equation in words and substitute the formulas into the equation. (We also have to know that acid-base reactions always produce a salt and water). \(\sf sodium~ bicarbonate + lactic ~acid \rightleftharpoons sodium ~lactate+carbonic~ acid \) salt (will break down further) Substitute formulas \(\sf NaHCO_3+\color{red}HC_3H_5O_3\rightleftharpoons NaC_3H_5O_3+ H_2CO_3\) salt (the \(H^+\) lost by lactic acid is highlighted in red) So where's the water (from the acid-base reaction)? Carbonic acid breaks down into water and carbon dioxide. \(CO_2\) gas is actually responsible for making the bread rise. \(\sf H_2CO_3 \rightleftharpoons CO_2+H_2O\) If we put these together we get \(\sf NaHCO_3+HC_3H_5O_3\rightleftharpoons CO_2+H_2O +NaC_2H_5O_3 \) Removing the spectator ions and showing the charges makes it a net ionic equation. \(\large \sf HCO_3^-+HC_3H_5O_3\rightleftharpoons CO_2+H_2O +C_2H_5O_3^- \)
