5.(2 points) Most of the sodium chlorate, NaCIOs, produced in the United States is converted into chlorine then used for bleaching wood pulp. luced in the United States is converted into chlorine dioxide, which is NaClO3(aq) + 2HCl (aq) - CIO, (g) + Cl2(g) + NaCl (aq) + H20 (1) a. How many milliliters of 12.1 M HCl are necessary to react completely with 35.09 g of sodium chlorate, NaCIO,? b. What is the maximum mass, in grams, of CIO, that can be formed from the complete reaction of 65 mL of 12.1 MHCI?
