Part B Refer to the observations of the test tubes from part A. Determine which metal (or hydrogen)

in each test tube is more reactive. Remember that the less reactive metal (or hydrogen) will

typically end up in pure form as an element, so no reaction will occur if the less reactive metal

(or hydrogen) is the one that begins in pure form.
