Percentage yield lab answers purpose the purpose of this investigation is to explore the percent yield of the precipitate in the reaction introduction for known amounts of reactants, theoretical amounts of products can be calculated in a chemical reaction or process. Thermite background: thermite is a powder made from aluminum powder and a metal oxide [usually iron oxide (fe2o3, known as rust)] the thermite reaction is a redox reaction, where aluminum reduces the oxide of another metal. Flinn scientific is the #1 source for science supplies and equipment both in and outside the classroom for more than 40 years, flinn has been the “safer source for science.
Thermite lab writeup thermite background: thermite is a powder made from aluminum powder and a metal oxide [usually iron oxide (fe2o3, known as rust)] the thermite reaction is a redox reaction, where aluminum reduces the oxide of another metal. Anyone who has seen any of the series of terminator movies knows that these resilient robots are terribly difficult to eliminate even in my dreams, it takes sheer luck and a nonexistent gun to survive a terminator programmed to kill me this writeup is intended to aid those whose lives have been or will be plagued by these tenacious cybernetic-organisms. Commenter mmarvin calmly explains that the whole point of using dcs on these chips is to show that the material is self-oxidizing thermite if you supply it with oxygen, any piece of carbon-contaminated crap will react and produce heat. Usually, though, we must finish the lab sometime in class we keep our lab writeup s in journals we copy down objectives , procedures, and all that good stuff, and put our data in the book the book has carbon-copy paper , so we can keep a journal and also turn in a copy of stuff to the instructor.
Termite lab report the effect of ink on termite behavior abstract termites produce special chemicals within their bodies called pheromones because termites are usually found inside dark areas, pheromones help them communicate in these places. Endothermic and exothermic reactions are chemical reactions that absorb and release heat, respectively a good example of an endothermic reaction is photosynthesis combustion is an example of an exothermic reaction. The second (partial) debunking of the full-length thrive movie this is part ii of the first debunking done on the full-length thrive movie there will be additional debunking material that is more detailed, both on the full movie and on various individual aspects of it, posted later. Calendar notes and hand-outs chemistry weekly agenda week august 16-18 wednesday : demos - methane bubbles and thermite circle reaction types in packet week 6 september 25 monday: double titration lab - write up intro and plan deadly chemistry lab. Now, jeff farrer, who did a good deal of the lab work, including figures 2-11 and fig 19 (the dsc test data) has also done unpublished tem work (a different, better kind of electron microscope), and he found traces of additional elements not reported in the paper on some of the chips: strontium and chromate.

Termite antennae have a number of functions such as the sensing of touch, taste, odours (including pheromones), heat and vibration the three basic segments of a termite antenna include a scape, a pedicel (typically shorter than the scape), and the flagellum (all segments beyond the scape and pedicel. Lab equipment guidelines formal lab report write up instructions lab equipment laboratory apparatus - 28 images - laboratory apparatus, image gallery lab apparatus, common lab apparatus by teaching, basic laboratory apparatus 171 caizer scientific, 25 best ideas about lab equipment on. I was hoping that those people at jref would challenge harrit et al empirically, ie to first agree on the empirical criteria for a positive identification of nano-thermite (or paint) and then join together in the lab to settle the issue. The evidence for the presence of thermite at the world trade center (wtc) on 9/11 is extensive and compelling this evidence has accumulated to the point at which we can say that wtc thermite is no longer a hypothesis, it is a tested and proven theory.

Years ago we covered using thermite to destroy a hard drive the idea is that if you melt through the platters, the data is completely unrecoverable there are tons of videos of people doing this. Context teenage mutant ninja turtles (“tmnt”) was an indie comic book launched in 1984 it was an underground parody of popular comics of that time, such as daredevil oddly enough it became a marketing phenomenon a few years later, with a massive media and merchandising presence during the late 1980s and early 1990s. In this home-science how-to from household hacker, we learn how to create an exothermic reaction by combining sulfur with iron, producing iron sulfide in the process for all of the details, including step-by-step instructions, as well as to see what happens when these two elements meet, watch this video guide.
