For 10 points, name this polyprotic strong acid with formula H2SO4.
In aromatic nitration, this compound deprotonates nitric acid in a classic electrophilic aromatic substitution reaction. This chemical is mass-produced with a process that uses a vanadium oxide catalyst, known as the contact process, which replaced the lead-chamber	 process. Oleum is called the [*] "fuming" type of this compound, and it is also known as "oil of vitriol." This compound is the acid in car batteries and it can be formed by adding sulfur trioxide to water, which occurs in the formation of acid rain.
