Fill in the blanks in the following table: Cation Anion Formula Name Lithium oxide 2+ 3- Fe? PO?4? Al? (SO? )? 2? 4? 3 Copper(II) nitrate Cr?3+ I? MnClO? 2 Ammonium carbonate Zinc perchlorate
Solution : Step 1: Let’s consider 1st set of data, i.e row 1 : Here we are given the name of the compound from which we have to predict the cation, anion and the molecular formula. The name of the compound is Lithium oxide. This compound is made of Lithium ion + 2- (Li ), which is a cation as it is metal and oxide ion(O ), which is a anion. Since the charges of the ions are not equal, the charge of one ion becomes the subscript of another. Hence, we write the molecular formula for L ithium oxide is Li O2
