The products are sodium nitrate and barium sulphate.
balanced equation :
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
when Cl2 is dissolved in water it generates ClO which is a good oxidizing agent since it gives out atomic oxygen. but dissolution of F2 cannot generate atomic oxygen since F is more electronegative than O
