WebNitrogen oxides are produced in the combustion process by two different mechanisms: (a) burn-ing the nitrogen in the fuel, primarily coal or heavy oil (fuel NO x); and (b) high-temperature oxidation of the molecular nitrogen in the air used for combustion (thermal NO x). Formation of fuel NO x depends on combustion conditions, such as WebSulfur dioxide. Sulfur dioxide is a colourless, pungent smelling gas that is a major air pollutant responsible for acid rain The sulfur dioxide released mixes with clouds and readily dissolves in rainwater SO 2 is a non-metal oxide so it forms an acidic solution in water, hence forming acid rain; Sources: combustion of fossil fuels - especially coal
