Case Analysis SUMMARY The article Moving U.S. White-Collar Jobs Offshore discusses how free trade is affecting our world today. “In the popular imagination for much of the past quarter century‚ free trade was associated with the movement of low-skill‚ blue-collar manufacturing jobs out of rich countries such as the United States and toward low-wage countries—textiles to Costa Rica‚ athletic shoes to the Philippines‚ steel to Brazil‚ electronic products to Malaysia‚ and so on” (Hill‚ 2011).

order to gain stability with each other (Larsen). To have stability which each other‚ the atoms share electrons so that their outer electron shell is equal. Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions (Larsen‚ 2010). Element that have a positive ion are able to bond with elements with negative ions. This is because the elements share the electrons so that the ionization becomes neutral and both atoms

Explain in your own words what it means for a chemical system to be in the state of dynamic equilibrium. After a reaction has occurred for awhile at a given temperature‚ the forward and reverse reaction rate will eventually be equal. Although you may get this confused‚ the concentration may not be
