2hbr(aq)+ba(oh)2(> 2h2o(l)+babr2(aq) write the net ionic equation, including the phases.

The net ionic equation is

2H+ (aq) + 2OH-(aq)→ 2H2O (l)

explanation

2HBr (aq) +Ba(OH) (aq)→ 2H2O (l) + BaBr2 (aq)

from the chemical equation above write write the ionic equation

2H +(aq)  +2Br-(aq) + Ba2+ (aq) +2OH-(aq)→ 2H2O(l)  +Ba2+(aq) +2Br-

cancel the spectator ions in both side( Ba2+ and 2Br-)

the net ionic equation is therefore

2H+ (aq) + 2OH-(aq)→ 2H2O (l)
