Problem 79E

Make a sketch of a concentration cell employing two Zn/Zn2+ half-cells. The concentration of Zn2+ in one of the half-cells is 2.0 M and the concentration in the other half-cell is 1.0 x 10-3 M. Label the anode and the cathode and indicate the half-reaction occurring at each electrode. Also indicate the direction of electron flow

Chemistry 1010 8/30/2017-9/1/2017 “Are all rocks the same”  Granite -Heterogeneous: we can see boundaries. Mixtures. Can separate -granite is composed of different rocks that have been crushed together  Chert -Homogeneous: we don’t see boundaries -property: if striked just right it will fall into flakes Distinguish Properties into 2 types 1. Physical -Changes that do not alter composition 2. Chemical -properties that a substance has that is involved in changing into another substance Techniques used for separating samples of matter  Heterogeneous separated by -sorting, decanting, filtration  Homogeneous separated by -distillation, crystallization (salt, sugar), chromatography Greek Philosophy Ideas of science go back to the Greeks. Best Greek Philosophers come from Athenian school.  Socrates  Plato First of the Greek Philosophers to start writing extensively. Explains many of the ideas that Socrates introduced. Theory of Form basic idea: there must be fundamental explanations for matter we experience. We can’t see the nature of matter but we can argue what it can be. The real world we experience is built up from a smaller and more perfect world.  Thales of Miletus He believed: Every sample of matter that we observe, is built on the fundamental essence of water.  Aristotle -His books become the essence of all western science till the Renaissance. -Chemistry of Aristotle science is based on the
