2NaCl+H2SO4=Na2SO4+2HCl

Explanation:

Since we have Na2SO4 on the right side
the left side must have a multiple of 2 NaCl's

Trying the minimum of 2NaCl on the left implies we will need to have a multiple of 2 Cl's in HCl on the right;

but the H2 in the H2SO4 on the left provides the 2H's needed for 2HCl to work out.
