net ionic equation for powdered barium oxide is mixed with water?

Answer 1

BaO + H2O ====> Ba+2 + 2 OH-

Answer 2

a. NH3(aq) + HNO3(aq) ---------> NH4NO3(aq) NH3(aq) + H3O+(aq) + NO3-(aq) --------> NH4+(aq) + NO3-(aq) + H2O(l) NH3(aq) + H3O+(aq) ---------> NH4+(aq) + H2O(l) b. Ba(OH)2(aq) + 2 HCl(aq) -------------> BaCl2(aq) + 2 H2O(l) Ba++(aq) + 2 OH-(aq) + 2 H3O+(aq) + 2Cl-(aq) ----> Ba++(aq) + 2Cl-(aq) + 4 H2O(l) OH-(aq) + H3O+(aq) ------------> 2 H2O(l) c. 3 HClO4(aq) + Fe(OH)3(s) -----------> Fe(ClO4)3 + 3 H2O(l) 3 H3O+(aq) + 3 ClO4-(aq) + Fe(OH)3(s) -----> Fe^+3(aq) + ClO4-(aq) + 6 H2O(l) 3 H3O+(aq) + Fe(OH)3(s) -----> Fe^+3(aq) + 6 H2O(l) d. AgOH(s) + HBr(aq) ------------> AgOH(s) + H2O(l) AgOH(s) + H3O+(aq) + Br-(aq) -----------> AgOH(s) + 2 H2O(l) AgOH(s) + H3O+(aq) + Br-(aq) -----------> AgOH(s) + 2 H2O(l)
