The Irish are a remarkable people. By that‚ I mean other people often make remarks about them. Remarks such as "Hey‚ that’s my bicycle!"‚ or "That’s the one‚ officer. He did it." But of course I’m joking. The Irish have many extraordinary talents. They are unsurpassed in the arts of literature and story-telling‚ and when they sing they will make you cry for losses you don’t understand but which need no understanding to be real. They are master brewers and distillers. They can wipe the morning dew

Identification of Unknown Organic Compounds by Melting Point‚ Boiling Point‚ and Infrared Spectroscopy Methods and Background The goal of this laboratory experiment was to determine the structure and identity of an unknown solid and an unknown liquid by using elemental analysis‚ index of hydrogen deficiency‚ infrared spectroscopy‚ melting point (for solid)‚ and boiling point (for liquid). In this laboratory‚ we were given unknown solid “C” and unknown liquid “D”. The empirical formula

Experiment No. 1: MELTING POINT AND BOILING POINTS OF ORGANIC COMPOUNDS ABSTRACT The properties of organic compounds depend on their chemical structures. Intermolecular forces of attraction affect physical properties such as melting and boiling point. Through the Thomas Hoover apparatus‚ the melting point of 8 test compounds was determined. Salicylic acid exhibited the highest melting point while naphthalene‚ the lowest. The stronger the intermolecular forces of attraction‚ the higher the melting

Laboratory Apparatus Beakers are useful as a reaction container or to hold liquid or solid samples. They are also used to catch liquids from titrations and filtrates from filtering operations. Bunsen burners are sources of heat. Burets are for addition of a precise volume of liquid. The volume of liquid added can be determined to the nearest 0.01 mL with practice. Clay triangles are placed on a ring attached to a ring stand as a support for a funnel‚ crucible‚ or evaporating dish.

have been theories developed on this idea throughout history from Descartes’s dualism to the common modern day theories of materialism‚ but even to this day there is the ongoing debate of which theory is right. Searle has a unique view called non-reductive materialism which challenges the premise of all other theories. To start off Searle points out the most commonly discussed issue of dualism‚ one even Descartes
