Answer :
The reaction equation is written as; SO3(aq) + H2O(l) ----> H2SO4(aq).
- The basic law in writing a chemical reaction equation is that the equation must be written in such as to ascertain that the number of atoms of each element on the right hand side of the equation is equal to the number of atoms of the same element on the left hand side of the reaction equation.
- For the reaction between water and sulfur trioxide, the reaction is written as follows; SO3(aq) + H2O(l) ----> H2SO4(aq).
