Explanation / Answer

Molecular equaton:

KF(aq) + HBr(aq) --------> KBr(aq) + HF(aq)

2 HBr(aq) + Ba(OH)2(aq) -------> BaBr2(aq) + 2 H2O(l)

Ionic equation:

K+ (aq) + F- (aq) + H+ (aq) + Br-(aq) -------> K+(aq) + Br-(aq) + HF(aq)

2 H+ (aq) + 2 Br-(aq) + Ba+2 (aq) + 2 OH-(aq) -------> Ba+2(aq) + 2 Br-(aq) + 2 H2O(l)

after canceling the common ions then we will get,

Net ionic equations:

F-(aq) + H+(aq) ------> HF(aq)

H+(aq) + OH-(aq) ------> H2O(l)
