2NaOH(aq) + H2SO4(aq) → Na2SO4(aq) + 2H2O(l)
In this reaction, sodium hydroxide (NaOH) and sulfuric acid (H2SO4) react to form sodium sulfate (Na2SO4) and water (H2O). The reaction involves the exchange of ions between the two reactants, resulting in the formation of new compounds. The coefficients in front of the chemical formulas ensure that the equation is balanced, meaning that the number of atoms of each element is the same on both sides of the equation.
