Hydrogen storage

Different technologies are available for the treatment of gaseous streams containing VOCs (Volatile Organic Compounds), namely catalytic or homogeneous combustion, absorption, adsorption, etc. The goal is either to recover the VOCs, or to destroy them, thus avoiding, in both cases, their emission into the atmosphere. The treatment of “lean” streams, where the concentration of the VOCs is particularly low (e.g. lower than 1% v/v), is a particularly challenging case study as the low concentration…

liters of liquid hydrogen could be used for? The Gargamelle Bubble Chamber is a large, cylinder shaped tank/chamber. It was full of pressurised liquid hydrogen. The camber was used to detect charged particles. The chamber needed many things to work, it detected bubble paths , and it took pictures to gather evidence of charges. The chamber worked by using neutrons, particles, charged plates, cameras, and liquid hydrogen. The chamber was first filled with hydrogen gas. The hydrogen gas was then…

In experiment 2, we observed that the reaction of halogenoalkanes with aqueous alkali and water which contains dissolved silver nitrate. Halogenoalkanes are alkanes which have one or more hydrogen atoms replaced by halogen atoms such as fluorine (F), chlorine (Cl), bromine (Br) and iodine (I) which are the elements in group 7 in periodic table. Halogenoalkanes have the general formula, RX, whereby R is an alkyl or substituted alkyl group and X is any of the halogen atom. Besides, halogenoalkanes…

In a chemical equation, there are the reactants, which is the part that is changed, and the products, which is what is left over. The reactant side and the product side must have the same quantity of each element. If they do not, the equation must be balanced by using coefficients. Mole ratios can be found by using these coefficients. Mole ratios are conversion factors and can be used to found the amounts of the reactants and the products in a chemical reaction. These can also be used to find…

ABSTRACT Within this experiment, the use of a bomb calorimeter was required in order to determine the heat capacity of the system through the combustion of three separate trials of benzoic acid. The resulting heat capacity values for each trial were averaged, with a standard deviation found as well. This was then used to work backwards, for a naphthalene trial, in order to calculate the change in energy (∆U) and the change of enthalpy (∆H). The accepted value for the change in enthalpy of…

of the compounds Germanium is in is Germanium hydride. Compounds don’t have symbols but they have formulas. Germanium hydride’s formula is GeH4. The 4 represents the subscript. A subscript is how many parts it is, so Germanium hydride is 4 parts hydrogen and 1 part Germanium. The uses for germanium are camera lenses, semiconductors, fluorescent lamps, and alloys. Germanium has a total of twenty five isotopes and only five are stable. Germanium’s compounds can cause pain and redness to eyes and…

reaction between silver and hydrogen sulfide, producing silver sulfide and hydrogen gas. The balanced chemical equation is 2Ag (s) + H2S (g) → Ag2S (s) + H2. This is a single replacement reaction. This reaction most commonly occurs through contact with hydrogen sulfide in the air - although direct contact with substances that contain sulfur can cause tarnishing. Silver tarnishes very quickly when it is exposed to air that contains high levels of ozone, sulfur, or hydrogen sulfide. Silver…

Buoy 21, Day Mark 1, Pelican Island Cut, and the Coast Guard Station. The main ingredient in saltwater is water. Water is composed of two hydrogen atoms and one oxygen atom that are covalently bonded and forms a polar molecule because the electrons are shared unequally. The unequal distribution causes the oxygen atom to have a negative pole and the two hydrogen atoms have a positive pole. The polarity of water makes it unique and allows it to perform as a solvent (Duke University, n.d.). Since…

different products: 1-heptene, Cis-2-heptene and Trans-2-heptene. However, the major product constituent was 1-heptene. Because Potassium TertButoxide is a bulky base, steric hindrance prevents it from attacking a hydrogen on a highly substituted carbon. Consequently, the base attacks a hydrogen on the least substituted carbon (primary carbon). In this case, steric hindrance is reduced and the elimination reaction is faster, so a less substituted alkene is more favored, and becomes the major…

Step (1a) include only dispersion forces, because each of the compounds are non-polar. In Step (1b), there are dispersion forces, hydrogen bonding, and dipole-dipole forces. Dispersion forces occur in all compounds, hydrogen bonding occurs between the oxygen and hydrogen atoms within each of the compounds, and there is also a dipole movement between the oxygen and hydrogen atoms. There is a correlation between IMFs and volatilities, as the stronger intermolecular forces tend to evaporate the…
