Sulphuric acid is an important chemical that is used to manufacture fertilizers like ammonium sulphate and potassium sulphate. It is also used to produce detergents, synthetic fibers, paint pigments, as an electrolyte in car batteries, and to prepare metal surfaces for electroplating. Sulphuric acid is manufactured via the contact process, which involves burning sulfur with air to produce sulfur dioxide, converting the sulfur dioxide to sulfur trioxide using a vanadium catalyst, and dissolving the sulfur trioxide in concentrated sulfuric acid to produce oleum and then dilute sulfuric acid. Sulfur dioxide released during the burning of fossil fuels can cause environmental pollution by dissolving in water to form acid

This passage provides a first-person account of a house fire that occurred on November 18, 1994. It describes the events from the perspective of a mother ("Sarah") who is awakened multiple times by a growing sense of panic and smoke in the house. When her husband screams for her to get out, she runs to their bedroom door but is blown back by heat and smoke. Coughing and gagging, she manages to grab her son Ben and get to his bedroom window, where she lowers him out as far as possible while flames grow behind her. In a sickening moment, she hears her husband jump from another window but he does not respond, causing her to scream his name amid the chaos and flames.

Sulphuric acid is an important chemical used to make fertilizers like ammonium sulphate and potassium sulphate through reactions with ammonia and potassium hydroxide respectively. It is also used to make detergents, synthetic fibers, paint pigments, and as an electrolyte in car batteries. Sulphuric acid is manufactured through the contact process, which involves burning sulfur with air to produce sulfur dioxide, converting the sulfur dioxide to sulfur trioxide using a vanadium catalyst, and dissolving the trioxide in concentrated sulfuric acid to produce oleum and then diluting it to make concentrated sulfuric acid. Burning of fossil fuels produces sulfur dioxide pollution which dissolves in water to form acidic rain
