Two amazing analytical chemistry students from a few years ago got the following results from the titration of an hcl sample: student 1: n = 8, x = 0.088713 m, 8 = 0.001006. student 2: n=6, t = 0.088293 m, s = 0.001441. are the two results statistically the same or different?

This statement about matter and its behavior is best classified as a

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.
