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?
The ions ClF2 and ClF2+ have both been observed. Use the VSEPR model to predict the FClF bond angle in each.
9.10 The kinetic energy of molecules is often used to induce chemical reactions. The bond energy in an O1 molecule is 8.221019J . Can an O2 molecule traveling at 780 m/s provide enough energy to break the O = O bond? What is the minimum velocity of an O2 molecule that would give a kinetic energy capable of breaking the bond if it is converted with 100% efficiency?
Which has the greater O—N—O bond angle, NO2− or NO2+? Explain briefly.
