Water exists in all three physical states only on planet earth, the only planet where life exists in the whole of universe. Water supports life on earth due its unique physical properties such as density, temperature variation, reflectivity, surface tension, specific heat, boiling and freezing points, as well as its chemical properties including its polar nature, dissolving ability and capacity to act both as an acid or base. The exceptional physical properties are all attributed to water’s…

of sulfur-rich geothermal hot acid springs, geysers, and deep ocean vents. While primarily an aquatic organism, S. acidocaldarius can also be found in hot acidic soils. Optimal conditions for S. acidocaldarius included a temperature of 80°C and a hydronium ion concentration, pH, of 2; making them acidophiles (acid loving) and thermophiles (heat loving). (Wikipedia #2). As a member of the Archaea Domain, S. acidocaldarius, has no peptidoglycan within its membrane. As such it cannot be classified…

The human body is built up with multiple organs. Each of these organs has a specific function or sometimes two. For example, the pancreas has two functions the endocrine and the exocrine. Also, each of these organs has to be balanced in order for us to be maintaining a good health. If these organs are not in the homeostasis state which means to regulate the internal environment and to maintain a stabilization, diseases can occur at any time. One of the disorders that can be seen if the…

precipitate. A precipitation reaction of Iron occurs upon mixing aqueous solutions of potassium hydroxide and iron chloride. When these two compounds are mixed the product is a salt, KCl and a precipitate of Iron hydroxide. When Iron is reacted with hydronium ion, it oxidizes by giving off two…

STAGE 2 Chemistry Assessment Type 1: investigation Folio Student Response: Issues Investigation INTRODUCTION Chlorine is considered to be the single largest contributor to safe drinking water in the history of public health. In 1902 the first chlorine disinfection system was installed in Belgium. By the 1920’s nearly the whole world started using the process. Due to this disinfection process many disease-causing microorganisms were abolished. According to Life Magazine (1997) “The…

Purpose: As derivatives of carboxylic acids, esters are abundant compounds that often contribute to the fragrances in flowers, fruits, and coffee. Esters are synthesized from either organic or inorganic acids through a process called esterification. In this reaction, a carboxylic acid (RCOOH) and an alcohol (R’OH) mix in the presence of a strong acid catalyst to form a neutral, water-insoluble ester (RCOO’R) that gives off a pleasant smell. The following is an example of this reaction: The…

we had to convert the pH level into exponential notation. From this, we were able to write the equation for the ionization of the 0.1 M acetic acid (CH3COOH). Then, we had to solve the equation by inserting the exponential notations of the hydronium ions, the acetate ions and the acetic acid into the equation. Throughout our experiments, our data was either recorded in our tables or on the packet given to us during these labs. In our first lab, our data was recorded on both our data…

In this experiment, the Law of Conservation of Mass was illustrated by performing a series of 5 reactions, including a precipitation reaction, a decomposition reaction, two redox reactions, and an acid base reaction on a copper wire, called the Copper Cycle. The initial and final mass of the copper were measured and percent recovery was calculated to demonstrate that mass wasn’t created or destroyed. The balanced equations, balanced formula-unit equations, total ionic equations, net ionic…

1. Which one of the following would make the most suitable catalyst in the decomposition of hydrogen peroxide (H2O2)? A. Carbon dioxide (CO2) B. Sodium chloride (NaCl) C. Magnesium oxide (MgO) D. Manganese dioxide (MnO2) 2. If the temperature of a reaction is decreased, what effect will this have on the rate of reaction? A. It will have no effect. B. The reaction will stop. C. The rate of reaction will increase. D. The rate of reaction will decrease. 3. Given the equilibrium reaction in a closed…

In this part of the lab, we pour 20 mL of Hydrogen Peroxide and 1 mL of yeast catalase in the reaction chamber and then submerge it in the water bath. After it was done, it can be concluded that the gas levels increased because when we first started timing it, the gas levels were at 76, but as time went by, the gas levels started to increase and in the end of the last interval, the gas level increased all the way up to 100. This result occurred because there were many active sites that were…
