most any material. GOOD LUCK! Abstract: In this lab we determined the freezing point‚ and Kf‚ of pure 2‚4‚dichloralbenzne as well as a 2‚4‚dichloralbenzne/biphenyl solution. We used this information to determine the molar mass of an unknown (#24) by the 3rd step in the experiment which was a 2‚4‚dichloralbenzne/unknown solution. All of the above we charted the time temperature for the later calculations. I. Introduction A. Background This experiment shows how one determines the temperature-composition

A New Addition I remember a long time ago‚ when my dad brought home a new addition to our family. She was about six weeks old and very afraid of everything around her. She was in a new world‚ a place that was an awakening in her eyes. Her fur was as soft as a cotton blanket and her attention span lasted as long as a blink of an eye. I remember watching my mom walk into the living room‚ with her hands on her mouth as she fell to her knees. A beautiful brown and white kitten‚ with streaks of golden

Nutritional qualities of dehydrated sapota Divya‚ A. R.‚ Manjunath‚ V.‚ Usha Ravindra Department of Agricultural Engineering‚ UAS‚ Bangalore-65 ABSTRCT To standardize a recipe for the preparation of sapota candy‚ the fruit was steeped in three different combinations of sugar syrup concentrations (20/30/400Brix‚ 30/40/500Brix and 40/50/600Brix) for osmotic concentration. The osmosed sapota slices were then dried at two different temperatures 55 and 600C. It was observed that candy product processed

Summary: Experiment 9 is conducted to identify the importance of intermolecular forces and how they affect molecules. Intermolecular forces are forces between molecules that determine whether the molecule is a solid‚ liquid‚ or gas under standard conditions. In our lab‚ we measured the maximum and minimum temperature reached and time it took to reach it of alcohols and alkanes. In addition‚ we measured the vapor pressure of the liquid at different temperatures. Through Experiment 9‚ we concluded
