# What is the chemical equation of potassium oxide and sulphuric acid?

$\text{K"_2"O(aq)+H"_2"SO"_4("aq")}$$\rightarrow$$\text{K"_2"SO"_4("aq")"+H"_2"O(l)}$
This is a type of double replacement (double displacement) reaction called a neutralization reaction. An acid and a base react to form an aqueous salt (in this case $\text{K"_2"SO"_4}$) and water.
