Please show me how to combine these ions and elements

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 themaking 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 ofan 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 fromcombining the ions at the intersecting rows and columns. Remember chemical formulas of ionic compounds do not show charges!CO32-PO 3-HCO 3FchemPadHelpchemPadHelpchemPadHelpchemPadHelpGreekXox" - =+GreekGreekGreekBaBaF2BaF 2Correct.chemPadHelpchemPadHelpchemPadHelpchemPadHelpGreekGreekGreekCsX_X" - -+GreekCSFCSFCorrect.chemPadHelpchemPadHelpchemPadHelpchemPadHelpGreekGreekGreekKXox" - =+GreekKFKECorrect.
