Daphny Maldonado Bio Lab 2107 Kiah Britton W 10-12:30 Is H20 Bad for You? Abstract: In the village of Gopher Hollow there’s a cluster of Blue Baby Syndrome. There were four infants affected by this cluster. The families from the infants would collect their water from wells. We have to determine what’s the source of the high levels of nitrites in the water. The four sources that could be the point of contamination are a new subdivision‚ textile plant‚ an organic farm‚ and a mountain lake

Date of Experiment: September 10th‚ 2013 Organic Chemistry II – CHLB330 Name: Symone E. MoxeyLab Partner: Lynden Cooper Synthesis of Aspirin (Acetylsalicylic Acid) Abstract:- Aspirin (acetylsalicylic acid) is produced experimentally in the lab. The resulting percentage yield is 65.5%. The purity of the obtained product is tested using the melting point and Ferric Chloride Test (FCT). The aspirin was massed‚ and the melting point was determined. Based on the data collected‚ there was a total

Comparison between unconditional acceptance of death by Simone Weil and Buddhist concept of passing away. "There is not any love or truth without an unconditional acceptance of death" Simone Weil "Gravity and grace" "I wonder if you have ever known what love is? Because I think death and love walk together. Death‚ love‚ and life are one and the same...To love‚ one must die." Jiddu Krishnamurti "On Living and Dying" Experiencing the death of a loved person‚ or witnessing

search- specific latent heat Q. Value for the specific latent heat of fusion of water: Specific latent heat is where the amount of energy (in joules) needed to change the state of 1Kg of a substance is called its specific latent of heat. You can calculate the amount of energy needed using the equation: energy (J) = specific latent heat (J/Kg) X mass (Kg) Material Specific heat of fusion (J/Kg) Specific latent heat of vaporisation (J/Kg) Water 334000 2260000 Lead 24500 871000 Ethanol

were conducted to find the specific heat of a metal as well as the heat of solution of a solid. Both experiments required the use of calorimetry to measure heat flow and temperature change. The specific heat of the metal was found by heating it in boiling water before transferring it to the calorimeter that was partially filled with water. After shaking the calorimeter‚ the temperature change was measured and recorded. This information was used to calculate the specific heat. The heat of solution
