Qualitative Analysis of Cations Short Overview The most common cations have been placed into five groups based upon solubility in aqueous solutions when different reagents are added. The reactions which occur are useful in identifying the presence of these cations in unknown samples. The process of identifying the cations is called qualitative analysis. The purpose of this experiment is to identify which cations are present in unknown solutions. A data sheet was not prepared for this experiment

Giant covalent structures: Diamond & Graphite They are both allotropes of carbon‚ meaning they are both different types of the physical form of Carbon. Diamond Structure: Giant covalent lattice of carbon atoms. Each Carbon atom is bonded to 4 others which tetrahedrally surround the atom. They have a high melting point as a large amount of heat energy is needed to break their bonds. They are unable to conduct electricity as they have no free mobile electrons to carry the current. Diamond

CHEM RESEARCH TASK 1. INDICATORS Identify and describe some everyday uses of indicators including the testing of soil acidity/basicity. • Indicators are used regularly in chemical laboratories during chemical reactions. One important use is to determine the end point of a titration when an acid reacts with an alkali. The reactants and products of such a reaction are colourless so an indicator is a useful way to visually determine when the reaction is complete. Chemists also need to monitor

Communication in Individualistic and Collective Societies CO 2520 Analysis 4.1 Shawn Fye-Potter Mr. Fey 8/5/2015 1. How do people in “individualist” cultures behave differently to people in “collectivist” cultures? People from individualist cultures tend to more independent and self-centered. The focuses on their cultural values tend to be related to their lives and what makes them happy as an individual. Collectivist cultures tend to revolve more around the family or community. Decisions

4’33”‚ a brief introduction to John Cage’s life is mandatory. Born in 1912‚ it can be deduced that most of Cage’s creative thoughts originated from his father‚ who invented the submarine that held the world’s record of staying underneath water (Nicholls 4). At a young age‚ Cage learned piano from his aunt who exposed him to music of the 19th Century and laid his foundation in music theory (Haskins 19-20). Despite being a top student‚ Cage dropped out of college after realizing that the education system
