The purpose of our investigation is to find the most efficient way to recycle cans( make them self- implode) to help the Oakland Recycling Center find the best process for them to recycle aluminum. This problem is important because it is important for us to start recycling cans in order for global warming to decrease in the world. Not recycling cans means that new aluminum cans will have to be made, and to make new aluminum cans people have to dig into the earth’s crust which wastes a lot of…

According to the average density and the boiling point of the experiment, the probable identify liquid of M4C is Propanol (Isopropyl alcohol), with the density value is (0.788 g/mL) and boiling point is (82.67 *C) compare with the literature value of density (0.785 g/mL) and the boiling point (82.4 *C), which Propanol (Isopropyl alcohol) should be the liquid of M4C. The Propanol (Isopropyl alcohol) has no color. The key of identify the unknown is the boiling point and the density, because if…

6°C. The boiling point range for the third fraction was 65.8°C to 67.7°C. The boiling point range for the fourth fraction was 78.8°C to 80.1°C. A gas chromatograph is a device that measures the content and the percentage of the tested sample. For the Gas Chromatography part of the experiment I injected a 2 microliter sample of each fraction into the Gas Chromatography to find the percentage of hexane, heptane, or octane is present in each solution.…

Last week in science class we worked on a lab called the Big Freeze. The objection of the project was to make a cooler and try to keep a block of ice frozen for 24 hours. For my cooler, I used a cardboard box, and put my ice container right in the middle of it and taped it down. Then I put bubble wrap on top of the ice container. After that I put a layer of aluminum foil on the bubble wrap and then put cotton balls and extra styrofoam on top of the foil. The last thing I did was put duct tape on…

For the controlled dH2O, it was hypothesized that no disks would float. The reason is because there is not enough CO2 for sample organism to absorb to allow it to do so. Looking at Figure 5.1, the slope of the line is y=0. This supports the hypothesis because there are no floating disks. For the 0.2% bicarbonate solution, it was hypothesized that if the leaf disks in this solution were placed under a lamp, then the disks would float. Figure 5.1 supports this claim, as there is an almost linear…

Carlissa Jones Mrs. Moscona Science Fair Abstract 2 February 2018 Particles in the Mist In this project, there was a cloud chamber built to see radioactive decay particles with a radioactive source. In this project an ionizing smoke detector is being used as the radioactive source. The difference between an ionizing smoke detector and one that is not is that they tend to respond 30-90secs faster to fast flame fires than photoelectric fire alarms. . A cloud chamber is a sealed environment…

Thu Doan Chem 2211-02 Fractional Distillation of a Binary Mixture 1. Explain why a packed fractional distillation column is more efficient than an unpacked column for separating two closely boiling liquids. Packing in the columns create more theoretical plates, which means better efficiency for distillation. The packed fractional distillation column provides a large surface area for heat exchange between the vapor and liquid. This allows for better separation between the liquids. 11. a) A…

HFOV and Gas Mixtures RES 262 Julia Fussell Sarah Bandy HFOV and Gas Mixtures The type of ventilation I will be discussing is High Frequency Oscillating ventilation. I chose this type of ventilation because of how different it is compared to traditional ventilation. “HFOV uses a constant distending pressure where an oscillatory flow along with clearly defined inspiratory and expiratory phases are generated in the lung”( adhb.govt.). Because the pressure is constant, it is easy to…

The melting point is the temperature at which a solid precipitate changes into its liquid form upon heating. It also helps when determine which isomers predominate. The experimental melting point of the E-stilbene was 242 degrees Celsius. The actual melting point of the E-stilbene was 241 degrees Celsius. This verifies that the predominating isomer is meso indicating that the cyclic intermediate remained. Therefore, almost no error occurred within the reaction since the two melting points are…
