Question

a.Write balanced molecular and ionic equations for eachreaction of a solid with HCl. HCl + CaCO3 HCL + precipitate form Ni(NO3)2 +NaOH b. Write balanced molecular and ionic equations for eachneutralization reaction in which heat was evolved. HCL + NH3 HC2H3O2 + NaOH a.Write balanced molecular and ionic equations for eachreaction of a solid with HCl. HCl + CaCO3 HCL + precipitate form Ni(NO3)2 +NaOH b. Write balanced molecular and ionic equations for eachneutralization reaction in which heat was evolved. HCL + NH3 HC2H3O2 + NaOH HC2H3O2 + NaOH

Explanation / Answer

a) 2HCl (aq) + CaCO3 (aq) ---> CaCl2 (aq) +CO2 (g) + H2O (l) Net Ionic: 2H+ (aq)+ 2Cl- (aq) +Ca2+ (aq) +CO3-2 (aq) --->Ca2+ (aq) + 2Cl-(aq) + CO2 (g) +H2O (l) 2HCl (aq) + Ni(OH)2 (s) ----> NiCl2 (aq) +2H2O (l) Net Ionic: 2H+ (aq)+ 2Cl- (aq) +Ni2+ (aq) +2OH-1 (aq) --->Ni2+ (aq) + 2Cl-(aq) + 2H2O(l) b) HCl (aq) + NH3 (aq) ---> NH4+(aq) + Cl-1 (aq) + Net Ionic: H+(aq) + Cl- (aq)+ NH3 (aq) --->NH4+ (aq) +Cl- (aq) + HC2H3O2 (aq) + NaOH (aq) --->NaC2H3O2 (aq) + H2O(l) Net Ionic:HC2H3O2 (aq) +Na+ (aq) + OH- (aq) --->Na+ (aq) + C2H3O2 (aq) + H2O(l)
