8 HNO3(aq) + 3 Cu(s) + O2(g) => 3 Cu(NO3)2(aq) + 4 H2O(l) + 2 NO2(g) Considering which elements are being oxidized and reduced, determine how many moles of electrons are transferred between the elements being oxidized and reduced. Scoring Scheme: 3-3-2-1 In step 2 of the experimental procedure, you added 6 M sodium hydroxide to the copper(II) nitrate solution to form copper(II) hydroxide. You added a minimum amount of sodium hydroxide, but enough to complete the reaction. How do you determine that enough sodium hydroxide has been added? In step 2 of the experimental procedure, you added 6 M sodium hydroxide to the copper(II) nitrate solution to form solid copper(II) hydroxide. What is the BALANCED chemical equation for the reaction in this step? Your Answer: c. Cu(NO3)2(aq) + 2 NaOH(aq) => Cu(OH)2(s) + You Scored 3 points out of 3 Possible 2 NaNO3(aq) 9) Scoring Scheme: 3-3-2-1 In step 3 of the experimental procedure, the copper(II) hydroxide was heated and decomposed to copper(I
