Thermal decomposition

Investigation of the Thermal Decomposition of Copper Carbonate Aim: Copper has two oxides, Cu2O, and CuO. Copper carbonate, CuCO3 decomposes on heating to form one of these oxides and an equation can be written for each possible reaction Equation 1: 2CuCO3 (s) Cu2O (s) + 2CO2 (g) + O2 (g) Equation 2: CuCO3 (s) CuO (s) + CO2 (g) The aim of this experiment is to prove which equation is correct. This can be done by volumetric analysis i.e. calculating the volume of gas produced. This is then

2.3 Ingredients Decomposition Oxidizer and binder decomposition play very significant role during the combustion of composite propellants. Inorganic oxidant and polymeric binder are the major components of their formulations and AP is the practical (still in use) oxidizer in the composite propellant formulations [26]. Available information on decomposition of binder in general and AP in particular have been collected and reviewed from the viewpoint of their application in the composite propellant

Beach Burial Beach Burial says only that men die and are buried. Is this a fair evaluation of the poem? Beach Burial is a poem which deals with many issues, not only about men dying and being buried. This is by no means a fair evaluation of the poem. The poem in actual fact deals with the problems in war, and it encases a hidden meaning, which is equality. This poem dwells heavily on the problems in war. It describes how high the death toll is for both sides. Slessor uses “convoys of

     It is stated by John Locke that in the state of nature no man may take more then he can consume. “…make use of any advantage of life before it spoils…whatever is beyond this is more than his share and belongs to others. Nothing was made by God for man to spoil or destroy. (Locke 14)” Locke then goes on to say, “God gave the world to man … for their benefit and the greatest conveniences of life they were capable to draw from it, it cannot be supposed he meant it should

Gabby more specifically thought the piglet on the concrete would decompose first because it is left in the sun. She thought the sun combined with the bugs would increase the rate of decomposition. If a piglet was left suspended it could be placed in the shade and less bugs would reach it. Laney thought, “Yes, it might decompose slower because everything goes to the head instead of staying in the original areas, or since everything goes

“The Three Ravens” is an english folk ballad, which was first printed in a song book Melismata compiled by Thomas Ravenscroft. It was published in the year 1611. It is a ballad about three ravens who take up a scavenger bird conversation about where and what they should eat for breakfast that morning. In the ballad “The Three Ravens” Thomas Ravenscroft uses personification and colourful imagery to discuss the ballad, and in the ballad the reader is led to expect something, but we discover a whole

Tollund Man is a 2400-year-old naturally mummified body that was discovered by two men who were digging peat for burning, in a danish bog in May 1950. Tollund Man was most likely a low- class slave from the Iron Age, who was killed as a result of being hung by a rope noose, because he believed in another god than his community, which suggested he was rebelling against his own community. According to the Danish police report, Tollund Man wore an iron neck ring, which was typically what slaves wore

As the search continued in the car, there was a smell of decomposition in the car. When Cindy Anthony first called the police she claimed “There’s something wrong. I found my daughter’s car today. It smells like there’s been a dead body in the damn car.” (Tru TV) later on when the car was taken by the police she said

it has grown from then to sub disciplines of forensic entomology with the medicolegal sub discipline being the most employed in criminal cases. The science behind forensic entomology is the integration of other areas of science, which are the decomposition timeline of bodies, the life cycle of insects and the types of insects that will invade that body and the knowledge of how to collect and rear them will help estimate the time between death and discovery, called the Post Mortem Interval, and with

skin or flesh left on the bones due to maggots and other insects. Piglet 1 still had maggots on its legs on day 9 and was decomposed on day 11 with only bones left. The piglet 10 still has not been completely decomposed on day 15. The speed of decomposition is different when the piglet is naked on the black top (piglet6) or a clothed piglet on black top (piglet 7). My initial thought was that piglet 6 would decompose faster because there would be one less layer to get through than on piglet 7. I was
