Baking Soda and Vinegar Rockets Introduction: Baking soda and vinegar are both compounds that can go off at any moment when it is applied. We had to see what would happen is we added 10mL of vinegar in the canister and see what amount of baking soda could make the canister go the furthers. We found out that this whole turning baking soda and vinegar to a rocket was going to be a chemical change. The chemical name for baking soda is (NaHCO3) and the chemical name for vinegar is (CH3COOH) and both…
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…
The percentage of uncertainty evaluates my data by showing how accurate my results are. The Sarsons and Pickling vinegar I titrated were extremely accurate as there was 0.04% and 0.05%of uncertainty, whereas the ASDA vinegar I titrated was 0.20% uncertainty; this was the highest percentage of uncertainty which shows that this vinegar is the most unreliable in order to compare to the results of the market stall vinegar titration. Conclusion: In conclusion trading standards believe that the…
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 first reasons that it is alike is when you turn the vial upside down it makes a does not stick to the sides of the vile. The same thing happens when you have citric acid and baking soda. When you shake the vial with the substance, it does not make a loud…
idea may be very simple, but requires great efforts because some developed countries have become so dependent on the combustion of hydrocarbons as an energy source. By limiting pollution such as sulfur oxides, nitrogen oxides, and carbon dioxide, acids would not be able to form within the atmosphere to create acidic solutions. The cut-off of air pollution would also solve other environmental problems. The solution seems to be to turn to renewable sources quickly to avoid further ocean…
It is well known that all organisms require at least some water to survive, even the most hardy creature on the planet earth, the tardigrade, Hypsibius dujardini, which can survive near complete dehydration, exposure to extreme radiation, vacuum, temperature and pressure, must be rejuvenated with water if it is to resume life after near complete desiccation (Gabriel, et al. 2007). H. dujardini, famous for surviving some of the harshest conditions of any organism we know of, is a perfect example…
either acid or base. Note: This activity may take more than one lessons. On the first lesson, students group, discuss and prepare their experiment. On the second lesson, students will have opportunities to carry out the investigation, then record, process, and evaluate their data. Preparing materials In the original experiment, hydrochloric acid and sodium hydroxide solutions have been used as acidic and basic solution, respectively. However, year 9 students might know that hydrochloric acid…
Determining the Chemical Formula of Hydrated Copper (Ⅱ) Sulfate Using the Empirical Formula Introduction In this experiment, the molecular formula of hydrated Copper (Ⅱ) Sulfate will be determined. In order to determine the molecular formula, the empirical formula is needed which is the ratio of moles of one substance to another. In this experiment, it is the ratio of Copper (Ⅱ) Sulfate to water. CuSO₄・XH₂O The empirical formula can be determined if the moles of the compared substances…
ACID-BASE PROPERTIES OF SODIUM CHLORIDE, SODIUM FORMATE AND AMMONIUM CHLORIDE INTRODUCTION The objective of this experiment is to examine the definitive characteristics of acids and bases by investigating the characteristics of strong versus weak acids; more specifically, why these differences are important in the process of titrations. In this experiment, there are two titrations performed and measured the pH of one salt solution. This experiment includes a strong acid and strong base…
quantity taken for amino acid analysis. Diluted hydrochloric acid was used for Free amino extraction. Nitrogenous macromolecules that were co-extracted were precipitated using sulfosalicylic acid and removed by filtration. A mixture of performic acid and phenol was used for Oxidation at 0°C. Hydrolysates of the sample were then adjusted to pH 2.2 using 7.5M sodium hydroxide sol. Amino acid analyzer based on ion exchange chromatography was used to separate amino acids. Amino acids were…
