TITLE: Toxicity Testing and Determining the LC50 INTRODUCTION: Our main objective for this experiment was to determine which three chemicals were going to be the most toxic to the brine shrimp by adding drops of vinegar‚ bleach and ammonia to the controlled water. We found that the vinegar was the most effective and the quickest. The ending results were very interesting when being compared to our hypothesis and we learned that some chemicals can react faster than others and each contains a different

Aishwarya Rana Professor Edison Williams English 101 09/09/2014 Why This Major? I entered this university with the sole purpose of getting a degree in the major I chose for myself. But this fall trimester‚ I came across some freshmen that had not decided their major yet. Watching them confused and lost‚ I caught myself thinking about different subjects and fields I could have taken. Not that I’m having second thoughts or anything but‚ I just wonder how I ended up taking business studies and not

Preparation of an Acetic Acid Ester Abstract: 14.1 g of octyl acetate were synthesized from the esterification process using 20.0 ml of acetic acid and 17.9 g of n-octanol. The theoretical yield was 23.8 g of octyl acetate. The percent yield was 59.2%. The purification of the final ester was confirmed by boiling point (186-199°C) and infrared index (nD=1.419). It was a colorless liquid that had a slight fragrance of orange and indescribable chemicals. The Infrared spectra confirmed ester

Dear diary‚ I was reading one of the latest teenage magazines today. I find them rather interesting and informative because they are full of very compelling articles about role models in sport and culture. in this generation. There was a very amusing article on a singer called Miley Cyrus. She is an interesting character. It is amazing to watch what happens to young celebrities‚ as they get older. Often‚ after many years in the spotlight‚ some celebrities appear to develop a very undesirable image

Michelangelo’s Sogno is a black chalk drawing on unprepared‚ cream-colored paper. Slightly larger than 8 x 12 inches‚ the drawing requires close-hand examination. At the center of the Sogno‚ an idealized male nude perches precariously on an open box filled with masks. His upper torso twists to his left as he leans on a sphere for support. He turns his head in the opposite direction‚ looking upward and over his right shoulder to watch a winged creature descent from above. Considerably smaller

Thermochemistry Laboratory Report Abstract The purposes of these three experiments are to determine the heat capacity of a calorimeter and with that data‚ confirm Hess’s Law and observe enthalpy changes within reactions. By measuring the change in temperature that occurs with the interaction of two different reactants‚ we were able to determine both the calorimeter constant and the change in enthalpy of a given reaction. The results were rather mixed‚ as some numbers more closely resembled the

In this local experiment‚ the goal was to use a polyacrylonitrile (PAN‚ (C3H3N)n) in addition to a chalcogel. This chalcogel is efficient at adsorbing I2 gas. Although just the chalcogel itself isn’t mechanically stable especially if it is to be used in the field for actual radioactive iodine capture. By creating a hybrid substance with the PAN and the chalcogel in a mixture‚ the theory is that they can create a mechanically stable efficient iodine capture method. This experiment did not study the
