Many free radicals combine to form molecules that do not contain any unpaired electrons. The driving force for the radical-radical combination reaction is the formation of a new electron-pair bond. Write Lewis formulas for the reactant and product species in the following chemical equation. Include nonbonding electrons. N(g)-->NO(g)-->NNO(g

1) Free radicals are molecules that contain an unpaired electron. Free radicals are important in many environmentally significant reactions. For example, photochemical smog smog that results from the action of sunlight on air pollutants -forms in part by these two steps: hy NO2 NO O O O2 3 The product of this reaction, ozone, is a pollutant in the lower atmosphere. (Upper atmospheric ozone is a natural part of the atmosphere that protects life on Earth from ultraviolet light.) Ozone...
Free Radicals are molecules or ions that have an unpaired electron. They tend to be very reactive and are thought to contribute to the aging process. A "dimer" forms when two of the same molecules combine (dimerize). Draw a Lewis structure for each of the substances below and indicate which are free radicals. For a free radical the unpaired electron goes on the least electronegative element, which is usually the central atom. Key: ... y = Yes ... n =...
Review Constants Periodic Tab Part A The gas-phase reaction of NO with F to form NOF and has an activation energy of E. = 6.30 kJ/mol and a frequency factor of A = 600-108 M. The reaction is believed to be bimolecular NO(s)+F2(g) NOF(g) + F(g) where NO is a free radical. Free radicals, species with an odd number of unbound electrons tend to be more reactive. This is one reason by NO reacts so readily with gases such as...
The first two pages are the background of the lab. I would
appreciate any help with the pre-lab questions, even if you cannot
answer them all, so I could continue to the post-lab on my own.
Experiment Thermodynamics: Entropy vs. Enthalpy OH, Background The formation of a Lewis Acid-Base complex occurs when you have a lone pair of electrons being donated to an electropositive ion or atom. Common examples are the Lewis Acid-Base complexes that most metal ions form in...
The first two pages are a background of the lab and there is a
page with the results. I would appreciate any help with this. If
needed I have the pre-lab questions as well. I added in the pre-lab
questions I will get them answered and updated again if that is
what is needed.

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
