7. For each of the following reactions, balance the net ionic equation on your own, reducing all coefficients to the smallest possible whole number ratios (no fractions) Then, write the correct coefficient X of the named substance. If the substance does not appear in the net ionic equation exactly as named, list the coefficient as zero. Read carefully each substance and the phase given in parenthesis. a. Solutions of dilute barium hydroxide and ammonium carbonate are mixed. i. X ammonia(aq) = b. Solutions of hydrocyanic acid and ammonia are mixed. i. XHCN = c. Barium iodide solution is added to solid silver sulfate. Hint: Silver iodide is insoluble. . X silver ions =
