This is my last chance on homework. Please make sure your correct. Thank you! :)

Answer 1

A) Balanced ionic reaction

HNO2 + KOH ------> KNO2 + H2O

The reaction is WEAK ACID + STRONG BASE reaction.

The extent of this reaction is above 50% as acid is weak , so won't dissociate completely.

B) Balanced ionic equation is

HNO3 + KOH -----> KNO3 + H2O

The reaction is of STRONG ACID + STRONG BASE.

The extent of reaction is 100% as components will dissociate completely.

C) Balanced ionic reaction is

2NH4Cl + Ba(0H)2-------> BaCl2  + 2NH3 + 2 H2O

The reaction is of STRONG (ACIDIC) ELECTROLYTE + STRONG BASE.

The extent of reaction is 100% as components will dissociate completely.
