$$Na_2SO_3_{(aq)} + 2HCl_{(aq)} \rightarrow 2NaCl_{(aq)} + SO_2_{(g)} + H_2O_{(l)}$$
In this reaction, \(Na_2SO_3\) reacts with \(HCl\) to produce \(NaCl, SO_2\), and \(H_2O\). The coefficients in the balanced equation are adjusted to ensure that the number of atoms of each element is the same on both sides of the equation.
