refractive index were measured for unknown liquid #16. The infrared (IR) spectrum of the compound was also taken. Based on the data collected‚ it was determined that the compound was likely to be salicylaldehyde. Introduction The purpose of this experiment was to determine the identity of an unknown organic liquid by measuring some of its physical properties. The properties were then compared to those of known compound to make an identification. The properties determined included density‚ boiling point

Down with the Top Ten Percent Many colleges try to have a racially diversified environment by using affirmative action. Some colleges used the point system which would give an edge to minorities over Caucasians. The supreme court of Texas prohibited colleges to use affirmative action. When affirmative action was prohibited‚ minority enrollments at colleges decrease. To racially diversify colleges‚ Legislature passed the top ten percent rule. The top ten percent rule states any high school
