In a biochemistry laboratory, carbon dioxide gas is generated to maintain specific incubator conditions. This can be achieved by reacting solid potassium hydrogencarbonate, KHCO3\text{KHCO}_3KHCO3, with dilute sulfuric acid, H2SO4\text{H}_2\text{SO}_4H2SO4.
Write the balanced chemical equation for this reaction.
