3. Suppose you pour 20 mL of silver nitrate into a beaker with 80 mL of water (H20) in it. You also pour 20 mL of silver nitrate into a separate beaker, but this one contains 80 mL of salt water (NaCl). Is the percent strength of the silver nitrate the same in both of these solutions

what two stable compounds when combined approximately 60 min later will form a strong solution of hydrochloric acid? 26 percent if possible

Can you please put the following that react with hydrogen peroxide (FeCl2, FeCl3, CuCl2, CuCl,ZnCl2) in an order from slowest to quickest decomposition? Please state an explanation to your answer as I am totally confused about the free radicals that are formed in each case that cause the reaction to speed up.

Thanks for any help that you can give!
