Substances burn more rapidly in pure oxygen than in air. Explain why.
Combustion reactions occur when any substance is burned. Research a particular combustion reaction and use any form of media that that explains the reaction itself, what happens when oxygen levels are limited, and the impact of this incomplete combustion.
Which of the following is not true? 1. When conditions are NOX-limited, the excess of VOCs in the atmosphere quickly oxidize available NO to NO2. 2. Reducing the concentration of NOX may lead to an increase in ozone formation when conditions are VOC- limited. 3. Smog episodes are not initiated during nighttime hours, because the hydroxyl radicals necessary to initiate the reactions are formed due to photodecomposition reactions. 4. Photochemical smog never occurs in areas without significant vehicle traffic and power plant emissions. 4. Metropolitan areas surrounded by wooded areas need to focus their smog reduction on limiting NOX concentrations due to the VOCs produced by surrounding trees.
MN IN The 1995 Nobel Prize in Chemistry was shared by Paul Crutzen, F. Sherwood Rowland, and Mario Molina for their work concerning the formation and decomposition of ozone in the stratosphere. Rowland and Molina hypothesized that chlorofluorocarbons (CFCS) in the stratosphere break down upon exposure to UV radiation, producing chlorine atoms. Chlorine was previously identified as a catalyst in the breakdown of ozone into oxygen gas. Using the enthalpy of reaction for two reactions with ozone, determine the enthalpy of reaction for the reaction of chlorine with ozone.
