Table 1: Water Observations (Smell, Color, Etc.) Beaker Observation 1 No smell and clear 2 No smell, oil and water don’t mix oil on top of water,look hazy 3 Little odor/can not determinethe clearnes 4 Slightly hazy/bubbles on top/no smell 5 The water is brown/no smell 6 Water is still brown/hazy no smell 7 Water brown/hazy/loud smell 8 Brown water/bubbles in soil Expriment 2- We compared and contrasted flitered water and comtaminated water. The contaminated water was brownish and had a loud…

For this catalase experiment it was decided that the group was to keep the concentration of catalase and hydrogen peroxide the same and only change the level of pH buffer throughout the experiments conducted. This was done to observe the effect different levels of pH buffers have on the breakdown of hydrogen peroxide and the volume of oxygen released. The results from the majority of experiments conducted reflect that though they are in consensus with the hypothesis that the volume of oxygen…

Chlorine is a chemical added to swimming pools to keep the water free of bacteria and algae. Chlorine levels in swimming pools vary based on how much chlorine has already been used to remove bacteria and how much sunlight has broken down the chlorine molecules. This means that pool owners spend a lot of time testing and adjusting the levels of chlorine in their pools. To reduce the amount of time spent on pool maintenance, pool chemical manufacturer's created chlorine tablets. These tablets are…

Merriam-Webster defines hypothermia as a condition in which the temperature of the body is very low. This condition is a medical emergency that occurs when the body loses more heat than what it is able to produce; hence, the body temperature decreases. The part of the brain called the hypothalamus is responsible for controlling body temperature; therefore, hypothermia is the result of the dysfunction of the hypothalamus. In order for a person to become hypothermic, their body temperature must be…

Conclusion: The the precipitation reactions lab eight out of the fourteen occurring reactions were precipitates. A precipitate means that a solid substance was formed or a substance that is not aqueous was formed. The reactions that did not form a precipitate were DNR, which means that they did not react. At station one barium chloride and potassium nitrate did not react but barium chloride and silver nitrate reacted to form barium nitrate and silver chloride. The precipitate at station one was…

A clean flame test wire was inserted into 0.2 M NaCl and also placed on the flame reputedly. A bright yellow persistent flame was a positive test of sodium being presented, then repeat the same instructions for the unknown ion. After the flame test wire was clean 0.2M KCl was dipped into the flame resulted a lavender color after several trials as well as the unknown solution. 10 drops of 0.1M Ca(NO3)2 in a test tube and 2-3 drops of 1M Na2C2O4, a white precipitate of calcium was present. The…

Purpose: To find the pH of different household items and to see what substances are acids or bases. To see how different substances neutralize each other. Hypothesis: I hypothesize that cleaning products will be bases and foods and substances we ingest will be acids. Materials: • Oil • Finesse Shampoo • Anti Freeze • Drain Opener • Hand Soap • Vinegar • Oxy clean • Pine-Sol • Hydrogen Peroxide • Apple Juice • Ammonia Procedure: 1. All materials were gathered, and safety goggles were put on.…

Both IR and UV spectroscopy are methods of measuring the wavelengths absorbed by a tested material. IR spectroscopy measures the absorbance of the tested material in the infrared spectrum, the section of the electromagnetic spectrum with a lower frequency than that observed in the visible light spectrum. Conversely, UV spectroscopy measures the absorbance of the tested material in the ultraviolet spectrum, the section of the electromagnetic spectrum with a higher frequency than that observed in…

In the results of the first trial, two lemons were used and the light bulb did not turn on. The voltage was 1.72v. When 4 lemons were used, the light bulb still did not turn on. The voltage was 2.89v. Then, with 6 lemons, the light bulb finally turned on. The voltage was 3.96v. The average voltage for trial one was 2.86v, and the range for trial one was 2.24v. In the first trial, the mode was not applicable. In the results of the second trial, two lemons were used and the light bulb did not turn…

Kale is such a powerful food to eat that more people should definitely be consuming. It's more prevalent in markets and in society, and still, a lot of people don't know much about it. Here are more fun facts about the plant that most people aren't aware of.
