’’? Describe what metal speciation is. How do the master variables of the environment relate to speciation? Why is speciation important in contaminant transport and in biological contexts? If you had to pick a third “master” variable‚ what would it be? Why is chemistry vital to understanding biological systems? Species refers to the form that a metal takes in the environment. This form can be a cation (ex: Fe2+) or anion form (ex: N3-)‚ or just a bonded form (ex: Fe2O3). Metal speciation‚ then‚ refers

alkali and alkaline earth metal ion 2. Define ground state and excited state of an atom. Ground state- normal configuration of the electrons about the atom or the ion of an element; stable particle electrons are at lowest possible energy level Excited state- when stable particles are heated to very high temperatures some of the electrons leave their ground state and become “excited”; these electrons move to higher energy levels 3. What is flame test? Why do different metals produce different colors

thereof‚ is a consistent motif found within both utopian and dystopian novels and movies. These stories provide a wide array of opinions about the role of machines in life. Certain authors‚ such as Bellamy‚ would argue advancements and use of machinery is necessary to push society to a better‚ brighter future. However‚ reading Forster’s The Machine Stops makes one question the influence of machinery in our lives. Technology‚ like most things in life‚ can be considered both enslaving and liberating

relying on it for essential needs. The Machine Stops is a short story by E.M. Forster that warns us of a possibility of a world that is dominated by a machine. The story is set in the distant future when humans are forced out of the surface of the Earth and depend on a machine housed underneath the surface for their every need; food‚ communication‚ housing etc. In return‚ this dependence has allowed mankind to be controlled by the machine.
