In a lab about the activity series, a solution of copper(ii)chloride is placed in a test tube with zinc metal. if zinc is higher up on the activity series, it will produce a reaction and replace the copper. bits of copper are seen in the bottom of the test tube. a good conclusion would be? a) zinc is lower on the activity series because there is no evidence of a reaction. b) zinc is higher on the activity series because there is no evidence of a reaction. c) zinc is lower on the activity series because there is clear evidence of a reaction. d) zinc is higher on the activity series because there is clear evidence of a reaction.
