 P: 4 1. The problem statement, all variables and given/known data For each of the following situations, identify those for which a reaction is liely to occur. For those that do occur, write a net ionic equation a) Chromium dipped into silver nitrate. b) 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. 2. Relevant equations solubility charts 3. The attempt at a solution I can't really figure out how to form a net ionic equation or how to get the charge but here is my attempt so far a) Cr(s) + 2 AgNO3(aq) -> Cr(NO3)2(aq) + 2 Ag(s) b) Au(s) + HCl(aq) -> no reaction c) Ni(s) + Ca(C2H3O2)2(aq) -> no reaction d) 2 Al(s) + 3H2SO4(aq) -> Al2(SO4)3 + 3 H2 e) Zn(s) + Pb(NO3)2(aq) -> Zn(NO3)2(aq) + Pb(s) if anyone can look over this i'd really appreciate it
 P: 4 i attempted to form the net ionic equations i'm just still not sure if this is correct. a) Chromium dipped into silver nitrate. Cr(s) + 2 AgNO3(aq) -> Cr(NO3)2 (aq) + 2 Ag(s) Therefore the net ionic equation is Cr(s)+2 + Ag(aq)+ -> Cr(aq)+2 + Ag(s)+ b) Gold immersed in hydrochloric acid. Au(s) + HCl(aq)-> no reaction c) Nickel pellets dropped into calcium acetate, Ca(C2H3O2)2. Ni(s) + Ca(C2H3O2)2 -> no reaction d) Aluminum dropped into a bath of sulphuric acid. 2 Al(s) + 3 H2SO4(aq) -> Al2(SO4)3 + 3 H2 Therefore the net ionic equation is 2Al(s)+3 + H2(aq)+ -> Al2(aq)+3 + H2(g)+ e) Zinc dipped into a solution of lead (II) nitrate. Zn(s) + Pb(NO3)2(aq) -> Zn(NO3)2(aq) + Pb(s) Therefore the net ionic equation is Zn(s)+2 + Pb(aq)+2 -> Zn(aq)+2 + Pb(s)+2
