5 - What is the name of Co(CN)3?
6 - What is the name of CuF2?

9 - The chemical substances in the first column of the table are either already shown as cations (because they are either polyatomic ions or variably valent elements), or they are known to form cations during the making of an ionic compound. The chemical substances in the first row of the table are either already shown as anions (because they are polyatomic ions), or they are known to form anions during the making of an ionic compound. When no charge is shown, you'll have to figure out what charge the element is expected to carry as an ion. Complete the table by writing the chemical formula of the compound resulting from combining the ions at the intersecting rows and columns. Remember chemical formulas of ionic compounds do not show charges.
