Consider the following reaction: Zn      +     2 HCl     -->    ZnCl2     +     H2   Assign oxidation numbers to each element in the following chemical reaction, state whether each reaction is a redox or a non-redox reaction. Indicate which species are oxidized and reduced in the spaces.  Oxidation number of zinc on the reactant side: Oxidation number of zinc on the product side: Oxidation number of chlorine on the reactant side: Oxidation number of chlorine on the product side: Oxidation number of hydrogen on the reactant side: Oxidation number of hydrogen on the product side: Is this a redox reaction?

Using the 5 types of reactions discussed in lecture, classify the following reactions andidentify whether or not they are REDOX reactions a. Fe(s) + Au(NO3)3 → Fe(NO3)3 + Aub. C5H10 + O2 → CO2 + H2Oc. H2CO3(aq) → CO2(g) + H2O(g)d. HNO3(aq) + Ca(OH)2(aq) → H2O(l) + Ca(NO3)2(aq)

Balanced net ionic equation: 3) Get two medium test tubes. Into one, place about 2 mL of a solution of hydrochloric acid. Into the other add a small amount of solid sodium carbonate. Note the appearances of the contents in the two test tubes and then mix them together noting any changes that have taken place. Change(s) that took place when the test tube contents were mixed: Balanced chemical equation: Balanced ionic equation: Balanced net ionic equation:

ment Booklet A2 1 - 12. A student listed the following possible reactants in redox reactions: 1. Iron and copper(II) sulfate solution II. Silver and calcium nitrate solution 13. The Reduction and Oxidation of Metals III. Zinc and lead(II) nitrate solution IV. Copper and lead(II) nitrate solution V. Magnesium and zinc nitrate solution Which combination will reacts spontaneously in a redox reaction? A. I and II B. I, III, and IV C. I, III, and V D. V only Which is least reactive with aqueous solutions of metal ions? A. Tin B. Zinc C. Gold D. Calcium 14. A block of magnesium attached to an iron pipeline running through moist soil may prevent the pipeline from oxidizing and corroding. Magnesium is a very reactive metal. When attached to the pipeline, the magnesium will corrode and keep the pipeline a cathode. Based on this form of protection, which of these metals can protect an iron pipeline from corrosion? A. Zinc B. Lead C. Copper D. Silver
