The glow sticks can operate by causing two chemicals to mix. A common reaction used for these devices is hydrogen peroxide and phenol oxalate ester. The hydrogen peroxide is kept in a thin‚ small glass vial in the middle of the stick‚ and the second chemical phenol oxalate ester is in the main body of the light stick. Bending the light stick in the middle causes the small glass vial of hydrogen

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

Lab 3: Hydrogen Spectrum Abstract When white light is viewed through a diffraction grating‚ we can see each component that makes up the light. However‚ when in an excited state‚ a gaseous element produces bright light of specific wavelengths rather than a continuous spectrum of colors. This phenomenon ultimately lead to the Neils Bohr model of the atom in 1913. Introduction In the middle of the 19th century‚ Robert Bunsen and Gustav Kichoff observed that gases emit spectral lines specific

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

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
