thermodynamic of CDRM represents as follow: CH_4+CO_2 □(→) 2CO+〖2H〗_2 ∆H_298=247 KJ⁄(mol ) (1) ∆G^o=61770-67.32 T This reaction above is highly endothermic which is favored by low pressure but, requires a higher temperature. A reverse water-gas shift reaction occurs as a side reaction as below CO_2+H_2 □(→) CO+H_2 O ∆H_298=41 KJ⁄(mol ) (2) ∆G^o=-8545+7.84 T Under conditions of…

Paragraph 1 The crystal chemical relationship between quartz (SiO2) and FePO4 can be studied by putting them under a temperature range of 294K to 1073K in an attempt to study the evolution of their structures. In doing so, we would able to examine the other quartz homeotypes that emerge during high temperatures and known to show a-b transitions. This study of quartz homeotypes were essential because the new information that was gathered would aid greatly in the creation of new products and more…

Experimental Conditions It is important to note that in our lab experiment we used galena, PbS, with 170 – 200 mesh (i.e. there were 170 to 200 wires per inch of sieve used to sort out the galena crystals). This means our diameter range of our particle size was 75-90 μm. Table 1:Experimental Conditions for PbS leaching FeCl3·6H2O (g) to be added is found by: The weight of FeCl3·6H2O (g) added in our experiment was slightly larger than the theoretical amount of FeCl3·6H2O needed, as can be seen…

Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. Chemical reactions vary greatly in the speed at which they occur. Some are essentially instantaneous, while others may take a very long time to reach equilibrium. The reaction is presented by The time in the reaction when the mixture remains colourless is the clock period. This will depend upon the initial concentrations of the sodium bisulphite ions (NaHSO3) and the potassium iodate ions…

Iodine clock reactions also known as Landolt Clock Reactions are one of many types of reactions in Chemistry. Clock reactions are an appealing way to show different type of chemicals having a reaction towards each other. This type of chemical reaction shows the demonstration of chemical kinetics. Iodine clock reactions were discovered by Swiss chemist Hans Heinrich Landolt in 1886. The procedure of conducting an iodine clock reaction consist of two colourless chemicals being mixed together.…

including misrepresentation of interbank borrowings as well as reporting incredulously low rates to allow the perception of financial health. Many banks were involved and colluding in these practices, therefore one can certainly conclude that the problem does not lie solely with the panel banks but the financial system and its governing regulators as well. LIBOR stands for London Interbank Offered Rate; it was intended to be a firm representation of the cost of funding for the largest…

model. The same participants will be studied at four different stages in the research to see not only the progress but also how effective the use of yoga and meditation is in the progress. The dependent variables are craving, depression, and Heart Rate Variability. The craving is the bio-behavioral phenomenon as it is related to physiological and psychological processes which happens inside and outside of conscious awareness (Eddie, Kim, Lehrer, Deneke, & Bates, 2014). Support of Method:…

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 the limiting reactant. A limiting reactant is the reactant that is used up and limits the amount of products formed. The other kind of reactant is the excess reactant, which is the reactant that is left over…

INTRODUCTION The trends in physical properties of organic compounds such as boiling points and melting points can be deducted from their structures, including size (molecular weight, surface area), shape and functional groups. These factors significantly influence the strength of the intermolecular forces of attraction present; and the nature and strength of intermolecular forces determine the variations in boilingpoints of organic compounds. The boiling point of a liquid is the temperature at…

Freezing and crystallization are linked in that both processes involve initial nucleation followed by crystallization. Sonication is thought to enhance both the nucleation rate and rate of crystal growth in a saturated or supercooled medium by producing a large number of nucleation sites in the medium throughout the ultrasonic exposure. Two main theories which explained the mechanism of nucleation are Hickling theory and molecular segregation theory. Among two theories Hickling is most commonly…
