Causes: The first element is a “lack of fit” between the people‚ particularly‚ Barbara‚ because she is not getting along with the new employees. The second element is the task of placing drink orders and as a result of the process not being fully mechanized‚ there were missing chits. The third element is the pattern of drink order incidents between two staff members resulting in poor service. Goals: The goal

Dynamics of mercury in the environment Mercury is a persistent‚ mobile and bio-accumulative element in the environment and retained in organisms. Because mercury is an element it is ultimately persistent; it cannot be converted to a non-mercury compound. Mercury in the aquatic environment is changed to various forms‚ mainly methylmercury. Once mercury enters into the environment‚ mercury permanently exists in the environment by changing its chemical forms depending on the environment. Figure as

hands. Background Information: When chemical compounds are heated‚ hey gain energy. The electrons in some of these chemicals will jump from their ground state electron configuration (such as the electron configurations we have ben drawing for the elements) to higher energy levels. As these electrons fall back to their original positions in the atom‚ they emit energy. One form of this energy is light energy. This is what you will be observing in this experiment.
