Explain both in detail please SCH4C-Chemistry Lesson 19 Key Question #19 . Consider the following REDOX reaction: Zn(s) + Pb+2(aq) â Zn+2(aq) + Pb(s) a. Write the oxidation and reduction half-cell reactions. (4 marks) b. Sketch the cell, label the anode and cathode and the direction in which the electrons are flowing. (4 marks) c. Show this reaction in shorthand notation. (2 marks) Some people claim that it is better to leave a car outside overnight during the winter, rather than in a warm garage, especially if salt is used on the roads. Give reasons for and against this claim. (4 marks) 2.
