Textbook Question
Chapter 8, Problem 91IL
A paper published in the research Journal Science in 2007 (S. Vallina and R. Simo, Science, Vol. 315, p. 506, January 26, 2007) reported studies of dimethylsulfide (DMS), an important green-house gas that is released by marine phytoplankton. This gas “represents the largest natural source of atmospheric sulfur and a major precursor of hygroscopic (i.e., cloud-forming) particles in clean air over the remote oceans, thereby acting to reduce the amount of solar radiation that crosses the atmosphere and is absorbed by the ocean.”
- (a) Sketch the Lewis structure of dimethylsulfide, CH3SCH3, and list the bond angles in the molecule.
- (b) Use electronegativities to decide where the positive and negative charges lie in the molecule. Is the molecule polar?
- (c) The mean seawater concentration of DMS in the ocean in the region between 15° north latitude and 15° south latitude is 2.7 nM (nanomolar). How many molecules of DMS are present in 1.0 m3 of seawater?

Consider the following chemical reaction between component A and B:
A(?) + 2B(g) → C(g)+ 3D(l) …..ΔH°r = −2253.2 kJ
i. State whether the reaction is exothermic or endothermic.
ii. Based on the value of heat of reaction, explain the chemical reaction above in terms of the energy associated with breaking or formation of molecular bonds.
iii. Consider a similar reaction of A and B as the one shown above. However, the reaction now generates D in vapor form instead of liquid. Explain how the heat of reaction value differs from the one shown above.
iv. If the above reaction occurs in an isothermal system where there is no work interaction and both kinetic and potential energy changes are too small such that they are negligible, write the energy balance for the system.
Hydrocarbons are not the only things subject to combustion. Elemental sulfur will burn brightly to form a combination of sulfur dioxide and sulfur trioxide. The electronegativities of oxygen and sulfur are 3.5 and 2.5, respectively.
Write two separate balanced equations for combustion of sulfur to these respective products
Assuming only combustion to sulfur dioxide, how many moles of sulfur dioxide are formed when 20 moles of sulfur react with 21 moles of oxygen gas?
Now assume 25% of the sulfur instead combusts to sulfur trioxide, and the remaining reactants combust to sulfur dioxide. Now how much of each product is formed from the same amount of the reactants?
Atmospheric sulfur trioxide is a major pollutant and cause of acid rain. Why might this be? (Hint: Consider the result of combining a molecule of sulfur trioxide with a molecule of water.)
Determine the molecular geometries of sulfur dioxide and sulfur trioxide. Are these molecules polar or non-polar?
