Determination of the heat of Combustion of Biodiesel Using Bomb Calorimetry
Abstract:
In this experiment, biodiesel fuel was synthesized from vegetable oil. Biodiesel is considered “green” and better for the environment because it is biodegradable. The heat of combustion was then determined using a bomb calorimeter.
Introduction:
Petroleum is the largest single source of energy consumed by the world’s population, exceeding coal, natural gas, nuclear, hydro, and renewables (3). It is predicted that global demand for petroleum will increase to 40% by 2025 (3). Biodiesel fuel is a renewable energy source made from vegetable oils and is viewed as an alternative for diesel engines. It is biodegradable and non-toxic, thus making it completely safe.

A few errors occurred when using the bomb calorimeter as well. The thread was not weighed in a few trials and one of the trials had the standardization on when it shouldn’t have been. When doing the titrations, many of the samples were overshot by a drop and some were way overshot as well.
A discussion section is where you interpret your results and discuss if your objectives were met. State the conclusions in terms of chemical concepts at the molecular level and rationalize the values of your results in terms of the chemistry behind the results. Tell me if your results make sense, discuss the accuracy of your results, and explain any important sources of error. You should answer any additional assigned questions at the end of this section.
Post Lab Questions:
1. Some advantages of biodiesel fuels compared to petroleum diesel are that biodegradable and non-toxic. It is also less polluting to the environment and heats homes. A major disadvantage is that it is more costly than petroleum and requires energy to produce biodiesel fuel from soy crops. It can also harm rubber hoses in some engines.
2. Affect viscosity and fluidity. Density will change with temperature change.
a) This would affect use in the winter months because it gels in cold

    1.0 IntroductionBiodiesel is defined as mono-alky esters of long -chain fatty acid. It is a fuel that derived from the vegetable oils, animal fats, which is similar to the diesel fuel except that it is made from the crops. It is produced from domestically grown, renewable sources, such as crop oils or animal fats which are then chemically converted into biodiesel (Habmigren, 2003). Unlike diesel, biodiesel contains no petroleum products and free of sulfur compounds and aromatics (Habmigren, 2003). Until today, it is still the only alternative fuel for motor vehicle. The biodiesel blends have ranged from 2/98% (B2), 20/80% (B20), to 100% (B100) (Hafman, 2003). The reasons biodiesel is a viable alternative to diesel from fossil fuels for trucks and buses are it can reduce the pollution, it can enhance the country's economy, and it is renewable sources and can produce almost same energy as diesel fuels.…

    The primary objective of this lab is to be able to determine the specific heat of a reaction by using a calorimeter. A calorimeter is a device used to determine the specific heat of chemical reaction or a physical change. The specific heat a reactions is used to refer to the amount of heat that is lost or gained when one gram of a particular substance increases or decreases by one degree Celsius. When a chemical reaction occurs in an open container most of the energy gained or lost is in the form of heat. Almost no work is done (i.e. nothing is being moved). Heat flows between the system and surroundings until the two are at the same temperature, when a chemical reaction occurs in which the system absorbs heat, the process is endothermic (it feels cold). When a chemical reaction occurs in which the system produces heat it is exothermic (it feels hot)…

    The experiment results fell a little out of range of the class average. The reliability of the experiment was high as most groups in the class results were consistent. The accuracy could have been improved by using digital thermometers and more accurate measuring cylinders and scales. Some or very little heat was lost from the metal cup due to surrounding environment. Also the position of the fuels source under the metal cup can affect the accuracy. As the condition of the experiments was kept the same for the groups, the experiment had a high…

    The resonance stabilization energy of benzene is investigated by the combustion of cyclododecatriene. The heat of combustion for cyclododecatriene was determined using bomb calorimetry and used to solve for the stabilization energy of benzene. The bond stabilization energy of benzene is found to be 167.6 ± 388.3 kJ/mol. This evidence that benzene has a resonance stabilization energy is possibly necessary for determining the structure.…

    For all 3 weeks, the calorimeter oval bucket (#13) was filled up with roughly 2.000 kg of DI water. The temperature of the water was roughly around room temperature (depending how long it was sitting in the room). The bucket was then placed in the calorimeter in a certain way. At the bottom of the bucket, there were 3 “dents” which were aligned with the dents at the bottom of the calorimeter jacket (#14). The oxygen combustion bomb (#15) was then opened and roughly 10 cm of the wire (metal wire provided by the instructor) was cut and attached to the arms of the cup so the pellet of choosing (which was either the Naphthalene or the Benzoic Acid) would ignite with the wire and thus causing the temperature to increase.…

    There are several reasons for these vast discrepancies. Firstly, the scientifically accepted results were calculated in a bomb calorimeter, a completely closed system. With the equipment available in the school laboratory, this kind of accuracy was impossible. There was no way of ensuring that the heat from the spirit burner only heated the copper beaker, instead of the surrounding environment. This dispersion of heat was the largest source of error in the experiment, and the reason for obtaining values significantly lower than those of other trials.…

    In order to use equation 13 it is also assumed that the temperature change of the water is the temperature change in the bomb calorimeter. The heat capacity of the bomb calorimeter (CVcal) was found to be 10.9kJ/K for the first trial of benzoic acid and 10.4kJ/K for the second trial. This gives a mean of…

    Background: Calorimetry is the science of measuring the heat of chemical reactions or physical changes. Calorimetry is performed with a calorimeter. A calorimeter can be any container from a cup to a Calorimeters need to be well insulated as calorimetry relies on the fact that temperature change only occurs within the solution and that no heat escapes to the surroundings. That is why it is important that calorimeters are well insulated. However, heat loss cannot be avoided so scientists, when conducting experiments, need to choose the calorimeter that allows least heat energy to escape, therefore, retaining as much heat within the solution…

    Materials: To complete all steps and smoothly complete the lab we first needed an almond, which what will be burned to find the energy and calories. Next we needed a paper clip to straighten out and put the almond on as a safe and efficient way to burn the almond. A scale and small aluminum-weighing dish were needed as well to weigh out the almond and paperclip. The lab also required a graduated cylinder, test tube, distilled water, thermometer, a Bunsen burner, a sparker, a calorimeter and safety glasses. All those were used for measuring, holding, heating and measuring the temperature of the water as well as measuring the energy content and the safety glasses were for protection when burning the almond.…
