1. The problem statement, all variables and given/known data For each of the following situations, identify those for which a reaction likely to occur. For those that do occur, white a net ionic equation. a) Chromium dipped into silver nitrate. b) Gold immersed in hydrochloric acid c) Nickel pellets dropped into calcium acetate, Ca(C2H3O2)2. d) Aluminum dropped into a bath of sulphuric acid. e) Zinc dipped into a solution of lead(II) nitrate. 3. The attempt at a solution This is what I got: a)Cr(s) + 2AgNO3(aq) --> Cr(NO3)2 + 2Ag(s) Separate the aqueous ions: Cr(s) + 2Ag(aq) + 2NO3(aq) --> Cr(aq) + 2NO3(aq) + 2Ag(s) Then I'm supposed to remove the ions common to both sides...but then I end up with none at all b/c each one is on both sides...??? b) no reaction c) no reaction d) 2Al(s) + 3H2SO4(aq) --> Al2(SO4)3(aq) + 3H2(g) Here I get the same problem as in (a) when I separate them. e) Zn(s) + Pb(NO3)2(aq) --> Zn(NO3)2(aq) + Pb(s) Again, same problem....if I separate the aqueous ions and get rid of the common ones I end up with nothing. What am I doing wrong? If someone can show me how to do this that would be great, thanks!
