change the actinic flux of ultraviolet (UV) radiation. Observations and numerical models show that UV-scattering particles in the boundary layer accelerate photochemical reactions and smog production‚ but UV-absorbing aerosols such as mineral dust and soot inhibit smog production. Results could have major implications for the control of air pollution. ABSTRACT Photochemical smog‚ or ground-level ozone‚ has been the most recalcitrant of air pollution problems‚ but reductions in emissions of sulfur

I am going to investigate the enthalpy change of combustion for the alcohol homologous series. I will investigate how alcohols with increasing number of carbons affect the enthalpy change when an alcohol goes under combustion. The energy that alcohols release when being used is called the enthalpy change of combustion. This is defined as "Standard enthalpy change of combustion‚ is the enthalpy change when one mole of a substance burns completely in oxygen under standard conditions (298K‚ 100 KPa

300‚000 dollars would go to children labor laws. Lewis Hine’s picture of the breaker boys is a very dismal image. The idea that children of age 14 are working in dark cramped spaces and that they are using dangerous machinery is scary. Also‚ the soot and dirt that is in the air gets into the kids lungs. This could stunt there growth and/or shorten their lives. Therefore‚ I find it very important for kids to have a healthy‚ growth-filled childhood and is why the 300‚000 dollars should go here.
