Why do equations A and D have reverse reaction arrows?


A H2CO3(aq) + H2O (l) Arrow H3O+(aq) +HCO3-(aq)

B LiOH(aq) →Li+(aq) +OH-(aq)

C HBr(aq)+H2O(l)→ H3O+(aq)+ Br-(aq)

D C5H5N(aq) + H2OArrowC6H6N+(aq)+OH-(aq)




because the products can recrystallize either way depending on the saturation


because water causes the reactions to reverse


because the reactions contain water and water never makes a good solvent for forming acids


because the reactants only partially ionize in the solution


because the reactions can proceed either way depending on the temperature

Answer 1

Answer:

answers in order C,A,B,D,because the reactants only partially ionize in the solution,none of these( SO4 2- is a strong one),none of these( all are weak),same(beacause both Ka and Kb values are equal in those subtances),di,mono,tri,mono,mono,mono,di,di,mono,Na2Be(OH)4(aq)...

Explanation:

this quiz doesnt worth my time...but have a nice day.
