Which is the correctly balanced chemical equation for the reaction of KOH and H2SO4? Which is the net ionic equation for the rea
NeX [460]

Answer:

See explanation

Explanation:

A balanced chemical reaction equation has the same number of atoms of each element on both sides of the reaction equation.

Hence, for the reaction between KOH and H2SO4, the balanced chemical reaction equation is;

H2SO4(aq) + 2KOH(aq) ---------> K2SO4(aq) + 2H2O(l)

Complete ionic equation;

2H^+(aq) + SO4^2-(aq) + 2K^+(aq) +2OH^-(aq) -------> SO4^2-(aq) + 2K^+(aq) + 2H2O(l)

Net ionic equation;

2H^+(aq) + 2OH^-(aq) -------> 2H2O(l)
