safe for kids to make. Difficulty: Easy Time Required: about 15 minutes Here’s How: 1. Basically‚ you make glowing slime by adding zinc sulfide or glowing paint to normal slime. I have a lot ofslime recipes listed. As written‚ these instructions make a clear slime that glows in the dark. However‚ you could add zinc sulfide to any of the recipes for slime with different characteristics. 2. The slime is made by preparing two separate solutions‚ which are then mixed. You can double

molecules be exposed to hydrogen peroxide. This will result in the rate of reaction increasing because it increases the chance of more successful collisions between the enzyme and the substrate. Catalase is an enzyme found in food such as‚ potato. It is used to break down a poisonous by-product of metabolism called hydrogen peroxide. Hydrogen peroxide is a compound that can kill cells therefore; it is essential that our body can break it up. Catalase breaks down hydrogen peroxide into oxygen and

Looking back at the research question‚ the actual amount of reactant did not match the theoretical stoichiometric amounts according to the balanced equation‚ but the amount of catalyst matched the original value when uncertainty is taken into account. The percent yields for the reactants in the equation are very far from 100% yield. In the case of water‚ the percent yield came out to be meaning there were at least 2 times to 4 times more water than there should be. The percent yield of oxygen came

Hydrogen has a high specific energy‚ high flame speed‚ wide range of flammability‚ and clean burning characteristics which suggest a possibility of high performance in internal combustion engines (ICE). These attributes have been realized for more than half a century since the onset of hydrogen engine development. In the early 1990s‚ FSEC conducted research on using hydrogen in an ICE. This work resulted in the development of a mixed fuel called HYTEST. Today‚ automobile manufacturers and DOE continue

dangers of sulfide mining. In Minnesota the conventional taconite and iron mining have not generally gone to arrange. In the 1960’s taconite was extremely mainstream in the economy‚ however in the following forty years a great deal of mining organizations shut down because of high rivalry. Nationals crosswise over Minnesota are not just terrified that a similar thing will happen‚ they are frightened of the dangers on sulfide mining and how it could influence them and their day by day lives.

Abstract: One is to determine the gap energy of cadmium sulfide semiconductor thin film using the equation: Eg = h.c/ is the signal of the long wavelength limit of the absorption peaks (measured in the lab). The reaction between cadmium sulfide and NH3‚ in the presents of thiourea yield a of 579(nm). The % error of the reaction is 1.24%. Introduction: There are 3 types of metals for electricity conducting: metallic conductor‚ semiconductor‚ and superconductor. Metallic conductors

San Francisco‚ January 23‚ 2014 - The global market volume for Polyphenylene Sulfide (PPS) is expected to be over 170 kilo tons by 2020‚ according to a new study by Grand View Research‚ Inc. Growth in global automotive industry; particularly in China is expected to drive the demand for PPS. In addition‚ the favorable regulatory scenario in China with regards to the automotive industry is expected to further augment the demand for PPS over the forecast period.

bombs and hydrogen bombs. The hydrogen bomb is the most powerful‚ destructive bomb of all. In this essay I’m going to give a brief history of the hydrogen bomb‚ the chemistry behind the bomb‚ and how much destruction the hydrogen bomb can do. After the Soviet Union’s atomic bomb success during the cold war‚ the U.S wanted something bigger and stronger. In 1950‚ President Harry S. Truman announced work on the hydrogen bomb. A group of scientists led by Edward Teller created the first hydrogen bomb in

<b>Thesis Statement</b><br>The hydrogen bomb is a nuclear weapon in which light atomic nuclei of hydrogen are joined together in an uncontrolled nuclear fusion reaction to release tremendous amounts of energy. The hydrogen bomb is about a thousand times as powerful as the atomic bomb‚ which produces a nuclear fission explosion about a million times more powerful than comparably sized bombs using conventional high explosives such as TNT.<br><br><b>The Hydrogen Bomb</b><br>The Atomic Bomb Was A Essential

As a noble gas helium is almost chemically inert‚ unreactive. After hydrogen‚ helium is the most abundant element in the universe. During an eclipse in 1868‚ French astronomer Pierre Janssen discovered helium. After Helium was proven to be an element it was named by a British chemist Sir Edward Frankland and British astronomer
