January 23rd‚ 2013 Generation of Hydrogen Gas Abstract Hydrogen gas was produced from a reaction in a eudiometer between a weighted amount of magnesium ribbon and 5ml of diluted 6M hydrochloric acid. The partial pressure of the hydrogen gas produced was calculated using Dalton’s Law of partial pressure. With this partial pressure value along with known values in the experiment the number of moles of hydrogen gas produced could be calculated using the ideal gas law equation and this experimental

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

Abstract Molar volume is the volume that one mole of gas occupies when temperature and pressure are kept constant. The molar volume of a gas can be determined through evaluating how much gas is given off when the number of moles of the substance is known. To find the volume of gas that will be used to calculate the molar volume‚ the process of water displacement can be used. Reference Citation Cesa‚ J. (2002).

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

First recognized as a chemical compound in 1818‚ hydrogen peroxide is a clear‚ colorless liquid most often used for cleaning or disinfecting(Britannica‚ 2013). Since pure hydrogen peroxide is unstable‚ it is found in stores as an aqueous solution. The chemical formula for hydrogen peroxide is H₂O₂ which means there are two hydrogen atoms and two oxygen atoms in the compound(Liebeskind‚ 2013). Seed germination is simply the process in which a seedling sprouts from a seed and begins it’s growth. The

Hydrogen is recognized as the simplest and lightest chemical element in the periodic table; even though it is identified as one of the top elements in abundance in the world (consisting of 0.9 percent of the total mass on earth)‚ it is considered to be the most abundant element in the entire universe. It is a gaseous element with the atomic symbol being H. It is usually categorized under the first group of the periodic table known as the alkali metals. It contains only one electron that revolves

However hydrogen peroxide it is a very dangerous substance when accumulated in large amounts. If that situation occurs this substance must be decomposed. But how can we decompose this reaction? Well it decomposes by itself
