Heading 1 Heading 2 Title Paragraph Styles 2) Four metals (A, B, C, and D) were studied for activity, and the following information was collected on the reactions between the metals and their salts: I) 2 A (s) + C(NO3)2 (ag) → No Reaction II) C (s) + 2 BCI (ag) → CC12 (ag) + 2 B (s) III) D (s) + B2S04 (ag) → DSO4 (ag) + 2 B (s) IV) 2 B (s) + 2 HCI (ag) → BC12 (ag) + H2 (g) V) D (s) + 2 AÑO3 (ag) → No Reaction a) Based on the above results, indicate the more reactive metal for each reaction: Most reactive> least reactive b) Would you expect A to react with sulfuric acid? Explain. 3)

4. Determine the oxidation numbers of each of the elements in the following reactions, and identify which of them are oxidized reduced, if any. a) 2 MNCOS(g)+ O:(g) 2 MnO:(s) + 2 CO:(g) b) 3 NO:(g) + H:O(1) 2 NO5 (aq)+ NO(g) + 2 H*(aq)

Consider the reaction below. Is this an oxidation-reduction? What information are you using to determine if this is an oxidation-reduction reaction.2 H2 (g) + O2 (g) à 2 H2O (l)
