Answer
Please see the work below.
Work Step by Step
a. The required balanced equation is:
$CH_3COOH+KOH\rightarrow CH_3COOK+H_2O$
The required ionic equation is:
$CH_3COOH+K^+ +OH^-\rightarrow CH_3COO^-+K^+ +H_2O$
The net ionic equation is given as
$CH_3COOH+OH^-\rightarrow CH_3COO^-+H_2O$
b. The required balanced equation is:
$H_2CO_3+2Na^+ +2OH^-\rightarrow CO_3^{-2}+2Na^+ +2H_2O$
The required ionic equation is:
$H_2CO_3+2Na^+ +2OH^- \rightarrow CO_3^{-2}+2Na^+ +2H_2O$
The net ionic equation is
$H_2CO_3+2OH^-\rightarrow CO_3^{-2}+2H_2O$
c. The balanced equation is:
$2HNO_3+Ba(OH)_2\rightarrow Ba(NO_3)_2+2H_2O$
The required ionic equation is:
$2H^+ +2NO_3^- +Ba^{+2}+2OH^- \rightarrow 2NO_3^- +Ba^{+2}+2H_2O$
The net ionic equation is:
$2H^+ +2OH^-\rightarrow 2H_2O$
