Kate Kirby June 6‚ 2013 Title: Extraction of an Unknown Compound Purpose: The purpose of this experiment was to separate a mixture of two or more unknown compounds and identify them based on their melting point and reactivity with an acid or a base. Compound studied/Reactions: The organic solvent used in this experiment was methyl t-butyl ether (MTBE‚ 2-methoxy-2-methylpropane). The unknown that dissolved in the MTBE‚ but was insoluble in water. MBTE is very volatile and flammable. It was

Carbon and Its Compounds Carbon: Introduction Atomic Number: 6 Electronic Configuration: 2‚ 4 Valence electrons: 4 Property: Non-metal Abundance: Carbon is the 4th most abundant substance in universe and 15th most abundant substance in the earth’s crust. Compounds having carbon atoms among the components are known as carbon compounds. Previously‚ carbon compounds could only be obtained from a living source; hence they are also known as organic compounds. Bonding In Carbon: The Covalent Bond

The compound pendulum Consider an extended body of mass with a hole drilled though it. Suppose that the body is suspended from a fixed peg‚ which passes through the hole‚ such that it is free to swing from side to side‚ as shown in Fig. 98. This setup is known as a compound pendulum. | Figure 98: A compound pendulum. | Let be the pivot point‚ and let be the body’s centre of mass‚ which is located a distance from the pivot. Let be the angle subtended between the downward vertical (which passes
