Ivan pavlov was born in Rtazan,Russia in 1849. His father was a priest and wanted Ivan to become a priest as well( Famous scientists.org,2016) . His father's name was Peter Dmitrievich Pavlov, and his mother's name was Varvara Ivanovna Uspenskaya(Ivan Pavlov,2016). Ivan was one of eleven children, Ivan was the eldest sibling in the group(Ivan Pavlov,2016). As a young boy he spent a lot of time in the garden, which got him interested in science(). He attended Ryazan Ecclesiastical high school;…

Reflection Paper Being completely undecided in my career path, and since I have taken all of the available chemistry classes, when the opportunity to job shadow a water operator at the Emlenton Water Treatment Plant arose, I took advantage of it. Even with my knowledge in chemistry, I went into the experience knowing only that they use chemicals, such as chlorine, to treat the water from the river. I came out of the experience with a more selective career path and a much greater knowledge and…

By using the pseudo first-order kinetics method, you are able to determine the rate law for the reaction between crystal violet and hydroxide ion. crystal violet hydroxide CV+ + OH- ————> CVOH Rate=k[CV+]m [OH-]n The objective for this experiment was to analyze the absorbance of the dyed molecule crystal violet using a colorimeter and the molar absorbance of the reactant. This data was used to calculate the concentration of…

In this experiment, we set out to determine the osmolarity of a potato. In order to do this, we placed potato pieces in seven different solutions of varying sucrose molarity. First, we weighed each potato piece to obtain the initial weight, shown in Figure 1. Then, we split the pieces vertically before placing them in the cubs containing the sucrose solutions. In each cup was a solution of sucrose with a molarity ranging from 0.0M to 0.6M. After placing the potatoes in the cups, we allowed them…

What I have found about this experiment is some really interesting ideas and other ways to the experiment. Some other people use Sodium or other words, for Sodium on the periodic table this chemical is called “Na” other people use that to make the Elephant Toothpaste. The call it Elephant Toothpaste because it’s supposed to look like toothpaste and since it's so big and it looks like toothpaste so the first thing people thought of was Elephant Toothpaste. Is that it was so deadly and that it…

Chemistry is a world many of us forget exist in our daily lives. We go about our routines, forgetting that chemistry plays a key role in our lives. As a skier, I noticed the unseen world of chemistry when I am preparing for ski races, waxing my skis. Preparing my skis for a race weekend requires applying multiple layers of wax to my skis. The wax we use is commonly a fluorocarbon mixture. In order for the wax to be saturated into the ski, the block must be melted with an iron. Once the…

the hair follicles, skin and the retina. Tyrosinase is also responsible for the brown color that forms on the inside of fruits and vegetables after they have been cut. The tyrosinase catalyzes the reaction with oxygen and catechol. Catechol is an organic alcohol found in most plants. Tyrosinase and catechol oxidases have a binuclear type 3-cooper center.…

This experiment monitored the synthesis of uridine from the deamination of cytidine through separating the contents of the reaction mixture using HPLC (High-performance liquid chromatography) at various time intervals since the start of the reaction. Cytidine and uridine standards are ran and the output of the HPLC will show two peaks based on the retention times of each compound. Identified the peak with the retention time of 2.422 minutes is cytidine and uridine has a retention time of 2.716…

1. 4 agar plates were poured several days ahead in preparation for this experiment. They were stored in a Ziploc bag in the refrigerator until ready to use. 2. To perform this experiment are the: cultures of E. coli, S. cerevisiae, and S. epidermidis, three plastic inoculation loops, candle and lighter, three poured nutrient agar plates, a disposable cup, alcohol, paper towels, bleach, a permanent marker, gloves, mask, apron, and goggles. 3. Be sure to wash hands carefully with disinfectant…

Emma Kilgore Science Period 2 January 12, 2016 The Evaporation of Liquids When a liquid is left in a warm car over a certain period of time some people might notice that the liquid seems to have lessened. This is because of evaporation, evaporation is when a liquid changes into a gas because of an increase in temperature or pressure. This brings up many questions having to do with liquids and evaporation so, do all liquids take the same amount of time to evaporate?…
