How is photochemical smog formed? What kinds of harm does it cause? When fossil fuels burn, some of the hydrocarbons in the fossil fuels are not fully burned. The heat causes nitrogen to combine with oxygen. The nitrogen oxide, hydrocarbons, and other air pollutants react with each other and the sunlight to form photochemical smog. The smog irritates breathing passages, harms plants, and damages rubber, paint, and some plastics. What substances can bind to form acid rain? Nitrogen oxides and sulfur oxides combine with water vapor to form nitric acid and sulfuric acid. The end The harmful effects of acid rain
