For 10 points, name this strong acid with chemical formula H2SO4.
This substance is added to chromium trioxide in order to form Jones' reagent. An alkyne can be converted to a ketone using a mercury-containing catalyst in a solution of water and this substance. The fuming type of this molecule is created when a certain trioxide is dissolved in it. In addition to forming oleum, this substance can be created using the lead chamber process. However, a process that supplanted it involves a vanadium oxide catalyst; that method is known as the contact process. For 10 points, name this strong acid with chemical formula H2SO4.
