Ozone Decomposition: Ozone formation is faster during the day due to the action of sunlight on NO, molecules. Thus, Os(g) accumulates in the troposphere and its concentration peaks sometime in the afternoon. During the night, ozone reacts with NO(g) according to the following reaction: NO(g) + O.(B) NO,() + O2(g). This is a single-step process with an activation energy E. = 12.5 kJ/mol and a AH-199.5 kJ/mol. PPB 5. Build potential energy diagram that represents the transformation of reactants to...

Atmospheric ozone plays a UV-A (320-400 nm), UV-B (280-320 nm), and UV-C (200-280 nm)
Atmospheric ozone plays a UV-A (320-400 nm), UV-B (280-320 nm), and UV-C (200-280 nm). Unfortunately, human-caused pollution has eroded the ozone layer in the stratosphere, allowing a greater amount of ultraviolet radiation to reach the Earth's surface. The damaging effects of the radiation can be related to it's photon energy. Arrange the regions of UV radiation from overall lowest to highest photon energy. role in absorbing high-energy and damaging UV radiation, including Lowest Photon Energy Highest Photon Energy. Which region of...

Sodium dodecylsulfate (SDS) plays an important role in SDS PAGE. Select each correct description of what SDS does in denatured electrophoresis. Choose one or more: A. Because SDS is a detergent, it supports the native state by interacting with the nonpolar portions of a protein, stabilizing the three-dimensional structure of a protein. B. SDS is an amphipathic compound that binds to the hydrophobic portion of the protein, coating the mixture and giving the protein an overall negative charge proportional to...
