2HCl (aq) + Na2SO3 (aq) - > 2NaCl (aq) + H2SO3 (aq)

Explanation:

HCl (aq) + Na2SO3 (aq) - > NaCl (aq) + H2SO3 (aq)

Let us balance the equation. This is illustrated below:

There are 2 atoms of Na on the left side of the equation and 1atom on the right side. It can be balance by putting 2 in front of NaCl as shown below:

HCl (aq) + Na2SO3 (aq) - > 2NaCl (aq) + H2SO3 (aq)

Now, we have 2 atoms of Cl on the right side and 1 atom on the left side. Thus, it can be balance by putting 2 in front of HCl as shown below:

2HCl (aq) + Na2SO3 (aq) - > 2NaCl (aq) + H2SO3 (aq)

A careful look at the equation proved that the equation is balanced as the numbers of the different atoms of the element on both side of the equation are the same.
