3 short answer questions about pollutants and detergents

1) Free radicals (see Problem 115) are also important in many environmentally significant reactions. For example, photochemical smog, which forms as a result of the action of sunlight on air pollutants, is formed in part by the following two steps. X NO2 NO O O O2 O3 UV light Ozone damages rubber products. The product of this reaction, ozone, is a pollutant in the lower atmosphere. Ozone is an eye and lung irritant and also accelerates the weathering of rubber products. Write Lewis structures for each of the reactants and products in the preceding

2) Aerosol cans carry clear warnings against incineration because of the high pressures that can develop upon heating. Suppose a can contains a residual amount of gas at a pressure of 755 mm Hg and a temperature of 25 °C. What would the pressure be if the can were heated to 1155 °C?

3) Water does not easily remove grease from dirty hands because grease is nonpolar and water is polar; therefore they are immiscible. The addition of soap, however, results in the removal of the grease. Examine the following structure of soap and explain why soap works. CH3(CH2)16C ONaO Nonpolar tail Polar head Sodium stearate a soap

1) Please see the attached image for lewis structures of each compound. Please let me know if something is lacking here!

2) We can use the relationship P1/T1=P2/T2. Also make sure to change the temperatures to kelvin and the pressures to atm!

755 ...

Solution Summary

In this solution we consider how to write lewis structures for NO2, NO, O, O2, and O3 in clear detail. We also apply a gas law to figure out the pressure after heating a can of spray. Finally, a brief discussion about how a detergent works is given.
