The propylene glycol is considered to be one of the common organic compounds which can be used in many life applications. It can be used in antifreeze, pharmaceuticals and many applications as well. It can be produced by hydrolysis of propylene oxide that is accelerated by the catalysis of base or acid. The goal of the experiment is to produce propylene glycol using water and propylene glycol as a reactant to synthesis propylene glycol. The purpose of doing this experiment is to converge and…

Jessica Vandeventer April 13, 2016 Energy Comparison of Fuels Purpose/Question- The Purpose of the lab is to see a comparison of fuels using a home made calorimeter. Hypothesis– The burner fuel is going to be a better source of fuel than the tea candle. Data Tables/ Graphs – Data Table 1. Mass and Density of Distilled Water. Mass of 10.0 mL of distilled water (g) Density of water (g/mL) 9.2g .92g/mL Data Table 2. Calorimetric Data. Fuel Source: Initial mass of fuel (g) Final mass of fuel (g)…

MATERIALS AND METHOD FOR BURN SCAR BIOMECHANIC BURN WOUND GENERATION All experiments and data collection were performed following approved protocols of the Ohio State University Institutional Laboratory Animal Care and Use Committee. A female red Duroc pig was maintained on standard chow ad libitum and being fasted overnight at other piggery. The animal had been anesthetized with Telazol and isoflurance. Anesthetic is a rapid and reversible drug-induced change in behavior or perception. Then…

African American women go through trial and error just to make sure their hair meet society standards. In the late 1940s, St. Paul, Minneota chemist and Jose Braquiel Calva invented the "chemical straightener", known as a hair relaxer today, has became very popular in the black communities over the years (Thompson 1). . Hair relaxers are designed to “glorify” and straighten the hair in a fast and easy process. Since the creation of hair relaxers, straight hair has been one of the many…

Vinegar Dilute and Impure Acetic Acid or better known as vinegar is a compound formed by the chemical reaction of carbon, hydrogen and oxygen. The composition of vinegar is acetic acid (C2H4O2) and water. Also, the formula for this compound is CH3COOH. These elements are nonmetals,so the type of bond that this substance made is covalent. Vinegar has many kind of properties and utilization in several ways. For example, it can be use for food preparation, cleaning and health. When added in…

Twenty kids one answer, who will figure it out. Everyone has been given the task to find the mystery mixture. At first they all had different clams. But now it is getting narrowed down. But there are some people that had different opinions. Everyone have been given water, a well tray, and a vial, along with other chemicals. I will explain how the class had gotten answer they did. And how they think it is right. The claim that will be explaining will be citric acid and baking soda. One of the…

We ran MgCl2 through various tests to see if its properties match our UWC. the first test was to compare the solubility of UWC and MgCl2. We added 1mL of distilled water to two different beakers each and gradually added 1g of MgCl2 and 1g of our UWC to each beaker. Approximately after 15 minutes, both solids dissolved in the water and MgCl2 passed this test. The second experiment was the halide test to determine if there are any Cl- ions in both solutions. We added 1 mL of 6M HNO3 and 1mL of…

Procedure: To begin this experiment all of the equipment was collected. The materials used in this experiment were a small plastic weighing dish, oxalic acid, a 250 mL Erlenmeyer flask, distilled water, a buret, NaOH solution, a 150 mL beaker, funnel, and phenolphthalein indicator. Before the experiment began the buret was cleaned with distilled water, a buret brush, and dish soap. The buret was completely washed out in order to not cause any faults in the results of the experiment. Once the…

In this experiment, the goal was to figure out which solute would be the best at neutralizing stomach acid the quickest. As baking soda was added to stomach acid, then the time for neutralization was the quickest. From the data chart, baking soda had the largest average pH of 6.6. On the graph, it show how baking soda had the highest peak and how it was the closest to reach 7 than any other substance. The hypothesis is supported because baking soda was the antacid that was closest to…

The number of moles of hydrochloric acid neutralizes for the three trials (2,4,5) were calculated using stoichiometry. It was calculated for trial 2 by convert 4.88 mL NaOH to L by divide by 1000 mL. Then, to get to mol of NaOH the molarity of NaOH was multiplied by 0.00488. Then to get from NaOH to HCl, the mole ratio 2 HCl to 1 mol NaOH was multiplied by 0.00122. To get the amount of HCl per beaker, 100 mL of HCl was divided by 1000 mL to get 0.1 L. Then, the liters were converted to moles by…
