Complete and balance each of the equations below, Refer to Figure A (the activity series page EX6-3) to determine if a single-displacement reaction will occur. If you determine that there will be no reaction, write "NR" next to the balanced equation. [For this experiment only, assume that copper a and lead will form +2 cations.)
