Hydrogen Selenide is toxic. It is made up of selenium which is also toxic‚ and hydrogen which is nontoxic. This substance is also colorless like hydrogen‚ but not like selenium which is a deep red color. There are reports of mine workers being poisoned by hydrogen selenide and selenium. Increasing industrial applications of selenium and the fact that workers may be exposed to Hydrogen Selenide have led authors to make a further investigation of the toxicity of this substance. The purpose of this

Chemist from the University of Glasgow in Scotland have taken a step closer towards producing clean hydrogen fuel in a maintainable way. Hydrogen gas is able to be burned to generate electricity without producing lethal releases‚ unlike fossil fuels. It is produced from water releasing them as gas‚ through a process called electrolysis‚ which uses electricity to break the bonds between hydrogen and oxygen. This technique is 30 times faster than the current method‚ and can be powered by renewable

Kinetic Expressions (Kinetics) has been taking place at Berea College for 20 years. This year the team celebrated its 20th by revisiting a choreography that was performed at the first Kinetics and were very purposeful of who they allowed to choreograph in this production. This will be a critique of some of the dances performed; it will go into detail about each dance‚ analyze the movements and reveal the message. The opening act to Kinetics this year was the choreography that was performed at

Michigan entrepreneur Justin Eric Sutton brings us into the era of clean hydrogen energy and solar energy‚ by producing a remarkable high speed MAGLEV railway which is being sold throughout the USA for deployment on Elevated Superhighway Rails‚ it speeds travelers between metro areas at up to 250+ MPH‚ in this remarkable vision of the not so distant future! Not only would it revolutionize energy AND transportation‚ it is both feasible and deployable TODAY. All that remains is funding and agreements

The North Korean state media released an official statement in December declaring a new weapon of mass destruction has been added to their arsenal: the Hydrogen bomb. In a statement released by a North Korean news agency on Tuesday‚ it was made clear that “the regime’s scientists are in high spirits to detonate H-bombs‚ capable of wiping out the whole territory of the US at once” (Vale). The testing of their alleged H-bomb was said to have occurred last Wednesday. Does North Korea have the right

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

Chemical Kinetic Models Simplified Global Chemical Kinetic Model In order to compare the two reactors used in our experiment‚ a simplified global kinetic model was used to describe the DRM reaction behavior in different plasma reactor. This model was already used by authors in the field of pollutant removal by using a plasma reactor [15‚ 21–23]. It is generally accepted that free radical processes are the main mechanisms in non-equilibrium plasma reaction [21‚ 24-25]. The chemical kinetics model

CHEMICAL KINETICS RESULTS AND DISCUSSION The balanced equation of the reaction between sodium thiosulfate and Hydrochloric acid is: S2O32- (aq) + 2 H+ (aq) SO2 (g) + S (s) +H2O (l) Using beakers with the same diameter was very important in conducting the experiment. If different sizes were used‚ the visibility of the “x” on the paper beneath the beaker could disappear from view too early or too late than the hypothetical time depending on the depth of the solution. It was also significant

Chemical Kinetics‚ A Clock Reaction Abstract The purpose for the experiment Chemical Kinetics‚ a clock reaction is to figure out the reaction rate of a solution regarding its concentration‚ temperature‚ and also determine the effects of when a catalyst is present. The experiment resulted that the concentration‚ as well as its temperature can affect the rate constant inversely the outcome of the rate constant. By conducting the experiment‚ it is also discovered that the rate order of the reaction
