Question

Review Constants One of the highest concentrations of peroxyacyl nitrates has been found in the Los Angeles (LA) basin at 30 ppb, reaching its peak at mid-afternoon. Most of the pollution in the LA basin is created in an area below the inversion layer is normally about 500 m. This concentration was therefore found in 1500 km of air above Los Angeles. Periodic Table only 3000 km and the pollution depth micl cmoe Free radical reactions catalyzed by ultraviolet light from the sun oxidize unburned hydrocarbons ketones, and dicarbonyl compounds, whose secondary reactions create peroxyacyl radicals, which combine with nitrogen dioxide to form peroxyacyl nitrates. These dissociate only slowly aldehydes, Part A On a day with a temperature of 15 °C and a pressure of 790.0 torr, how many grams of peroxyacyl nitrates are found in the air above Los Angeles (1500. km3) if the concentration is 30.0 ppb by moles? The molar mass of the major peroxyacyl nitrate, peroxyacetyl nitrate, is 118.03 g/mol. carry nitrates to sites other than their place or origin regions in the troposphere where ozone can be produced more readily. Peroxyacyl nitrates are both toxic and irritating and even dissolve more readily in water than ozone. Even a few parts per billion can cause eye irritation and higher Express your answer to three significant figures and include the appropriate units.
