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: \text { I) } 2 \mathbf{A}(\mathrm{s})+\mathrm{C}(\mathrm{NO3}) 2 \text { (aq) } \rightarrow \mathrm{No} \text { Reaction } \text { II) } C(s)+2 \text { BCl (aq) } \rightarrow C C l 2(a q)+2 \text { B (s) } \text { III) D (s) + B2SO4 (aq) } \rightarrow \text { DSO4 (aq) + 2 B (s) } \text { IV) } 2 \mathrm{~B}(\mathrm{~s})+2 \mathrm{HCl}(\mathrm{aq}) \rightarrow \mathrm{BCl2}(\mathrm{aq})+\mathrm{H} 2 \text { (g) } \text { V) D }(s)+2 \text { ANO3 (aq) } \rightarrow \text { No Reaction } a) Based on the above results, indicate the more reactive metal for each reaction:

b) Would you expect A to react with sulfuric acid? Explain.
