Bottle A Lab Report

433 Words2 Pages

To start, the first hypothesis was supported. The first hypothesis stated that when the level of water increases, there will be a higher pitched sound when blown over. Bottle C; the bottle with the most water; fifteen and a half centimeters; produced the highest pitched sound. The waves in the bottle reflected between the top of the bottle and the surface of the water which had a seven-centimeter difference, to create a shorter wavelength and higher frequency. Bottle A was filled five and a half centimeters of water which caused the lowest pitched sound. Contrarily to bottle C, Bottle A had the longest wavelength and smallest frequency because there was a seventeen-centimeter air column for the waves to reflect back and forth.
Secondly, the

    The absorbance and the maximum wavelength of all eight standard solutions were determined using the same spectrophotometer in this section. First, approximately 3 mL of each solution was added into a cuvette using a plastic pipette. The solution was added until the level reached the frosty part of the cuvette and any bubbles were dislodged by gently tapping the cuvette against a hard surface. Then, a Kimwipe was used to clean the exterior of the cuvette. Once cleaned, the cuvette was transported by only holding the top edges.

    We are doing a gummy bear lab. Gummy bears come in different sizes, shapes, and colors. Gummy bears are squishy, chewy, and sticky, they are made of sugar which are glucose and glucose are carbohydrate. We predict that during this stage of lab the solute and solvent will go through the stages of hypertonic, hypotonic and isotonic. We get 4 gummy bears and 4 cups filled half way with different types of liquid, such as Salt-Water, Coffee-Creamer, Vinegar, and Soda.

    The lab started off by measuring critical materials for the lab: the mass of an an empty 100 mL beaker, mass of beaker and copper chloride together(52.30 g), and the mass of three iron nails(2.73 g). The goal of this experiment is to determine the number of moles of copper and iron that would be produced in the reaction of iron and copper(II) chloride, the ratio of moles of iron to moles of copper, and the percent yield of copper produced. 2.00 grams of copper(II) chloride was added in the beaker to mix with 15 mL of distilled water. Then, three dry nails are placed in the copper(II) chloride solution for approximately 25 minutes. The three nails have to be scraped clean by sandpaper to make the surface of the nail shiny; if the nails are not clean, then some unknown substances might accidentally mix into the reaction and cause variations of the result.

    Group 1: All the elements that were tested from group 1 had a pH level of 12. This meant that all the tested elements produce an alkaline solution. Group one elements readily lose their valence electron as they wish to form a full valence shell this gives them all a low electron affinity. The group one elements have different electronegativity going down the group. Electronegativity of the elements decreases with the increasing the atomic radii.

    ST Report In the experiment, the problem was the contaminants that were affecting the quality of the water samples. To fix this issue, three scientists had to determine the contaminants that were present in the samples. One sample was from the school sink and the second sample was from an unknown source. The scientists conducted many tests to figure out what pollutants were present in the water.

    Our objective was to pick the best chemical to be used in a hand warm. This chemical had to be cheap, relatively safe, and must raise the temperature by 20oC and no more. We add 6 different chemicals to water we record the inshell temperature and then add one a the 6 chemicals to the water and record the temperature change of the water. We also add cold water hot water together to find how much heat would escape the calorimeter. We found that the calorimeter absorbed 71.1J/oC. Then this information to calculate the energy that was released by all of the chemical reaction.

    The solution with pH 3 has a higher H+ concentration than the one with pH 12. The numbers 12 and 3 signify whether a solution is acidic, neutral, or basic (alkaline) based on the concentration of hydrogen ions contained within the solution. If an anthocyanin molecule is added to a solution and releases a proton once being added into the solution, the anthocyanin molecule is behaving like an acid. A proton (or a hydrogen ion), is being lost, which is a characteristic of an acid. When anthocyanin molecule is being added into a solution, the double bonds shift and its color changes depending on whether the solution is acidic or basic.

Then we were to classify each type of solid as either ionic, metallic, non-polar molecular, polar molecular, or network. Paraffin wax classified as a non-polar molecular, Silicon dioxide was classifies as a network, Sodium chloride was classified as ionic, Sucrose was classified as polar molecular and Tin was classified as metallic. (2)The intermolecular forces that are present in Paraffin wax are dispersion forces, because it is non-polar and carries a negative charge. Followed by Sucrose that has

    The purpose of this lab was to observe the phenomenon of resonance in an open ended cylindrical tube and use resonance to determine the velocity of sound in air at regular temperatures. A hypothesis for this lab was that if the frequency of the tuning fork increased, then the length of the tube to achieve resonance will increase because of the high amplitude of the vibration. The resonance of the open-closed tube was found through these steps. First, the tube was filled with water with an inner tube inside the outer tube. The water temperature was measured.

Sugars are converted to ethyl alcohol when fermentation happens. In this experiment we determined if yeast cells undergo fermentation when placed in a closed flask with no oxygen. Glucose and yeast are mixed together in a closed flask and allowed to incubate for about one hour.
