67 Resure ne shew ell mur calculations end te include units end errorr sixeificant ficures fer ell econcreas celculariens For Port A: What observations did you make that indicated a chemical change had occurred ? Did a reaction occur for Cu metal in (a) zinc nitrate? (b) In lead nitrate? Did a reaction occur for Zn metal in (a) copper (ii) nitrate? (b) In lead nitrate? Did a reaction occur for Pb metal in (a) copper (ii) nitrate? (b) In zine nitrate? Write the balanced chemical equation for each spontaneous reaction which occurred. What is the activity series for the three metals

tested? Are the metals

which did react being oxidized or reduced in these reactions? What does that mean in terms of electrons?
