The purpose of the lab was to find which of the three balanced chemical equations was correct using decomposition & stoichiometry. After getting the necessary supplies for the lab, get the crucible and weigh it on the scale. After that, reset the scale so that it shows all zeros. Then put a certain amount (10,00 g), set up the ring stand and bunsen burner, so you can heat the crucible and baking soda effectively. The lab procedure and data supports the hypothesis, that if baking soda is heated, then it will decompose into 2NaCO3 → Na2CO3 + CO2 + H2O. Doing the experiment, our experimental value was 6.18, which was closest to reaction 3, at 6.18, the expected value. Several errors could have of occurred during the experiment. One common error…
why certain things decompose faster than others? I was interest in doing this project because I’ve always wondered why certain things decompose faster than others, and why they decompose. For my science fair project I want to find out why what types of decomposition there are, and how the process of decomposition works. I like to observe the tiny things in life, and why it works, or why it happens, and I feel like I could gain some knowledge on biodegradable, compostable, and decomposable…
Crematorium Embalmer: The lady at the crematorium showed us the crematory machine and went through what happened to the bodies inside them. She also went in depth into the world of embalming and how that was done. She showed us the two chemicals added to the bodies in preparation for their funerals, that were preservatives called arterials and formalin. The funeral director also informed us all that when someone loses their teeth to drug addiction, she has a plastic insert that is placed between…
September, 10 there were a total of 10 piglets placed outside. Nine piglets were placed inside of a cage, and one was buried in the ground while in a box around 4.00’pm. All of the piglets were dead before birth, and have not had a single breath of oxygen air. Piglet one was lying in the grass naked without clothes. Piglet two was naked with first and second and degree burns all around its body. Piglet three had a stab wound; it didn’t penetrate the other side. Piglet four was naked and had a…
Americans are misrepresented in the history of mortuary practices. Native American embalming consisted of four ritualistic steps. First incisions are made length wise along only the back of the deceased body. The flesh is then removed from the body in one large piece. I have a unique insight into this process because I have been a part of it. A body came into the funeral home with a fatal shot from a small caliber round to the head. The interesting thing about small caliber injuries is that…
A Step-by-Step Guide to Mummification Introduction The guide will be most useful to anyone wanting to invest their time into a career as an Anubis priest or an embalmer. It will also have a specific relevance to novice embalmers. This manual will goes through the guidelines and process that is involved with mummification. By familiarizing workers with this manual it allows for a higher level of precision and understanding when preparing our figures for dead. Uniform As a priest you are expected…
Insects are the reason our bodies actually decompose. They are drawn to the stench of cadaverine and putrescine once your body starts producing it. As stated before, when an individual dies, their body starts to decay about 4 minutes after their heart stops beating and their cells are deprived of oxygen. Insects, such as blowflies, seek out damp orifices to lay their eggs in. After the bloat stage of decomposition the body becomes open to its surroundings and insect activity tends to increase…
involves the transfer of electrons between two reactants. These reactions were identified as a redox reaction because of how they turned into a different color, signifying there was a transfer of electrons which changed the physical appearance of the solution. In order for the reaction to be redox, a chemical substance has to be used up in the process and it has to create a new chemical substance. It also had to have a transfer of electrons between each other, if there is no transfer, then the…
Feb). The more advanced methods overcoming drawbacks of the PP method when the modes are spaced closely are frequency domain decomposition method (FDD) (Brincker R, Zhang L, Andersen P (2001) Modal identification of output-only systems using frequency domain decomposition. Smart Mat Struct 10:441–445) or complex mode indication function method (CMIF) (Shih CY, Tsuei YG, Allemang RJ, Brown DL (1988) Complex mode indication function and its applications to spatial domain parameter estimation.…
Chemical Reactions I Purpose The purpose of this experiment was to test and see how four different chemical reaction worked. The four different chemical reactions are formation, decomposition, single-replacement, and double-replacement. The hypothesis of this experiment was that in each of the different reactions something would happen to the reactant whether it be color, mass, temperature, or pressure. II Equipment For this experiment Late Nite lab was used. In Late Nite Lab the equipment…
