Cu(s) + HCl(aq) ---> No reaction
The net ionic equation for the reaction between HPO42- and HCl is: HPO42- + 2H+ -> H2PO4- + Cl-. The spectator ion in this reaction is Cl-.
Apparently this is a trick question. Cu is too low in reactivity to actually have a reaction with the acid. So there is no reaction. Cu + HCl --> N/R
Nothing happens:Br- + I- + HCl --> Br- + I- + H+ + Cl-
The ionic equation for HCl and KHCO3 is H+(aq) + Cl-(aq) + K+(aq) + HCO3-(aq) → KCl(aq) + H2O(l) + CO2(g). The net ionic equation is H+(aq) + HCO3-(aq) → H2O(l) + CO2(g).
HCl + NH4OH -> NH4Cl + H2O

HCl + NH4OH -> NH4Cl + H2O
The net ionic equation for the reaction between HCl and Na2CO3 is 2H+ (aq) + CO3^2- (aq) -> H2O (l) + CO2 (g). This indicates the formation of water and carbon dioxide gas as products.
Only H+ (from the strong perchloric acid) and H2PO4- will react, but ClO4- and Na+ will not and stay unchanged in solution.H+ + H2PO4- --> H3PO4
The net ionic equation for iron II chloride (FeCl2) and copper (Cu) is: Fe2+ (aq) + Cu(s) → Fe(s) + Cu2+ (aq)
Molecular equation: CuSO4 + Na2CO3 → CuCO3 + Na2SO4 Net ionic equation: Cu2+ + CO3^2- → CuCO3
2 HCl + Pb --> PbCl2 + H2 (for Pb 2+) 4 HCl + Pb --> PbCl4 + 2 H2 (for Pb 4+)
The net ionic equation for the reaction between NaOH and HCl is: OH- + H+ --> H2O. This equation represents the formation of water from the combination of hydroxide ions and hydrogen ions. Sodium and chloride ions are spectators in this reaction and are not involved in the formation of the products.
The net ionic equation for the reaction between hydrochloric acid (HCl) and magnesium (Mg) is: 2H⁺ + Mg(s) -> Mg²⁺ + H₂(g)
