This experiment was a Landolt Iodine clock reaction - Oxidation of Bisulphite by Iodate. It involved conducting three measured experiments. The first variable tested was concencentration. This was tested by conducting two experiments‚ each varying the concentration of either the NaHSO3 or KIO3. The varying of NaHSO3 involved using 0.1 Molar of KIO3 against decreasing concentrations of NaHSO3 (0.25 M‚ 0.125 M‚ 0.0625 M and 0.03125 M). When decreasing the concentration of KIO3‚ 0.25 M of NaHSO3 was

be God during these awful catastrophes? Why doesn’t God intervene and stop the evil before it happens? John K. Roth expresses his opinion on God and Evil in the book Encountering Evil. Roth explains God in the midst of evil by a Theodicy of Protest‚ which he mentions can also be expressed as an anti-theodicy. Roth easily gets flustered at other theodicies because they defend God. Roth quotes‚ “Most people want a totally good God or not at all” (Pg. 7). He believes in God but also believes God should

Introduction Reduction/Oxidation (Redox) reactions are ones that change the oxidation state of a compound. The oxidation state refers to the acquired charge (gained or lost electrons) of an element in relation to its original charge (i.e. S + 2e- S2+); in a compound‚ the overall oxidation state is calculated by adding all the charges of the elements present. The addition of electrons makes the element “reduced” and the loss of electrons is called “oxidized”. These reactions can be carried out

Module 16 Notes Reduction/Oxidation Reactions • Oxidation number: The charge that an atom in a molecule would develop if the most electronegative atoms in the molecule took the shared electrons from the less electronegative atoms. • Oxidation numbers are not real; they are only based on assumptions. They are useful bookkeeping tools though‚ and can help us keep track of electrons during a reaction. • The sum of all oxidation numbers in a molecule must equal the charge of that molecule. • Rules

Think Like a Freak “What Do King Solomon and David Lee Roth Have in Common? Jayla Helton ECON 202 Summary The beginning of this chapter starts off talking about Solomon wanting to have judgment over something. He was given that opportunity when 2 women came to him saying how they had both given birth to a baby boy. This encouraged one to become guilty‚ and one to be innocent. This chapter continues on giving stories discussing the idea of being innocent‚ and guilty

More so than I expected while reading Joseph Roth’s The Emperor’s Tomb was the extent that class divisions contributed to the cultural climate of pre-1914 Austria. While modern-day scholars may be interested in studying the rise of anti-Semitism‚ especially considering the rise of Nazi Germany in the aftermath of World War I‚ certain passages of The Emperor’s Tomb show that amongst the aristocratic intellectual elite‚ class divisions overcame anti-Semitic sentiment. Class divisions were engrained
