Just use a solubility chart! Find the cation on the far left and the anion on the top and find where they connect. If it says "s," it is not soluble. If it says "aq," it is soluble. Here, ZnF (Zinc Fluoride) is soluble. Hope that helps! :)
P.S. Not all of the compounds above are on this particular chart. In future problems, just google "solubility chart" until you find one with all of the compounds you need to look at.
