In the titration of the dry unknown sample with the secondary standard solution, sodium EDTA, we must examine each of three acceptable trials. Enter the mass of your dry unknown sample in GRAMS, for each your three acceptable trials. Your mass precision should be reported to a thousandth of a gram

The equation below shows the reaction of zinc with hydrochloric acid (hcl). zn (s) + 2 hcl (aq) —> zncl2 (aq) + h2 (g) what will happen if the concentration of hcl is decreased? a. more zncl2 will be produced. b. the reaction rate will slow down. c. the hydrochloric acid will become more acidic. d. the reaction will produce water instead of hydrogen gas.
