You need to be able to write the formulae of the compounds from their ions, unless you are given them already and you just have to balance them.
Here goes ...
Na2SO4(aq) + BaCl2(aq) --> BaSO4(s) + 2NaCl(aq)
It's a precipitation reaction - you'll see cloudy white barium sulfate forming. Take a look at this Bitesize page: www.bbc.co.uk/school...
I hope this helps.
