Spontaneous reactions occur without outside intervention. In an isolated system‚ natural processes are spontaneous when they lead to an increase in disorder‚ or entropy. They may occur quickly‚ like the combustion of hydrogen‚ or slowly‚ like when graphite turns to diamond. Ex: Ammonium nitrate dissolves spontaneously in water‚ even though energy is absorbed when this reaction takes place. H2O NH4NO3(s) NH4+(aq) + NO3-(aq) Ho = 28.05

THE HAMMER PFC GREEN‚ ALEX J. B CO 1/325th AIR 2 AUGUST 2013 The Hammer A hammer is a tool meant to deliver an impact to an object. The most common uses for hammers are to drive nails‚ fit parts‚ forge metal and break apart objects. Hammers are often designed for a specific purpose‚ and vary in their shape and structure. The term hammer is also used for some devices that are designed to deliver blows like the cap lock mechanism of firearms. The hammer is a basic tool of many professions

interpretations within one artwork though its subject matter and materials‚ my first artwork was also a problem solver. Mysterious Island (2010) by Istvan Orosz‚ (see Image 1) consists of a cylindrical mirror on top of a drawing‚ so that the flat and distorted graphite drawing is transformed into a three dimensional reflection in the mirror. The drawing done on the paper is distorted and its subject matter looks different

Chemistry 1225 Lab Write-Up #13 Abstract Electrolysis is a method of using a direct electric current to drive an otherwise non-spontaneous chemical reaction. During electrolysis‚ hydrogen atoms (H2) are reduced at the cathode whereas the oxygen atoms (O2) are oxidized at the anode. There were three different solutions used in the experiment in order to have a better understanding of electrolysis reactions. From each solution‚ reaction equations were produced. The reactions could be observed from

The purpose of this lab was to find out the reaction of iron nails and CuSO4‚ copper sulfate solution. Before starting the experiment‚ there were two possible outcomes of the reactions. CuSO4 + Fe → FeSO4 + Cu or 3CuSo4 + 2Fe → Fe2(SO4)3 + 3Cu. The ion chart showed that iron can only make two charges‚ +2 and +3. As the liquid evaporated‚ the weight changed because the liquid added to the nail’s weight. In a real world situation‚ scientists can use ratios to determine how much of a substance that

The Chernobyl Nuclear Power Plant Disaster It is a silent enemy‚ it has no odor‚ no smell‚ no shape‚ yet it is one of man’s deadliest foes. Radiation is not something most people face on a daily basis‚ but for the town of Prypiat in the Ukraine it is a barren wasteland because of it. The Chernobyl Nuclear Power Plant disaster was the worst nuclear catastrophe to have ever occurred and‚ is a perfect example of what can happen when the blind and unmasked furry of atomic power is left unharnessed

As technology continues to develop in sport‚ new composite materials are replacing the old traditional materials. Tennis rackets are no longer made of wood and sheep intestines but instead have been replaced with graphite and the strings are now made of nylon. This essay intends to discuss how old materials have been replaced by new composite materials‚ the manufacturing process and the benefits to the designer and consumer. Due to new technology‚ the tennis racket has changed materials. Throughout
