**Question #3: Completing and Balancing the Equation** **a) Write the balanced chemical equation for the reaction that occurs when an aqueous solution of iron(III) oxalate is combined with an aqueous solution of calcium bromide by filling in the boxes below.** For each pair of boxes, write the numeric coefficient needed to balance the equation in the first box and the chemical formula of the reactant or product in the second box. Be sure to use the smallest possible integer coefficients. A coefficient of 1 must be entered. Do not include phases. Canvas will not allow you to enter a subscript for a chemical formula; to show subscripts, use the underscore. For example, CaCl₂ would be entered as CaCl_2, N₂S₃ would be entered as N_2S_3, and Al₂(SO₄)₃ would be entered as Al_2(SO_4)_3. There is a table with pairs of input boxes for entering coefficients and chemical formulas, but the table itself is not detailed in the instruction text.
