Retrieved January 31, 2017. The basic concept that is being explored are about enzymes. Enzymes are proteins that are known for being sparkplugs in a chemical reaction. Enzymes have a shape and for them to ‘spark’ they must have the proper substrate for it to work U. This does not change the enzyme’s…

The CEO of a large perfume factory needs to know the best way of safely transporting n-hexanol, which is used in manufacturing perfumes, to his factories. Therefore, the purpose of this experiment was to find the most beneficial way to transport an alcohol. Specifically, if transporting n-hexanol in hot or cold temperatures works best or if another alcohol should be used. A volatile liquid is a liquid that evaporates readily at room temperature or a liquid that has a measurable vapor pressure…

In this lab experiment, we will be using an unknown volatile liquid in order to understand the direct relationship between the molecular weight of a gas and its vapor density, which will help us determine the molecular weight of the unknown. The necessary tools that are essential in this experiment include: a balance, watch glass, two pieces of foil (2.5x2.5 inches & 3x3 inches), boiling chips, a ring stand, a thermometer, a bunsen burner, and an 800mL beaker. During this experiment, we have to…

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.…

(e) Dalton’s Law Challenge Question: Ordinary air contains about 78% nitrogen, 21% oxygen, and small amounts of several other gases. As a diver descends, the pressure of the air he is breathing increases by about one atm for every 10 m of depth. Oxygen may become toxic and cause convulsions if it is breathed at a pressure above 1.4 atmospheres. According to Dalton’s Law, at what depth should a SCUBA diver be concerned about oxygen toxicity if he is breathing ordinary air? Discussion Points: •…

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…
