Alkali

(6) This process involves water and potassium hydroxide to decompose the body where all that remains is bone ash. (6) The corpse is placed in a pressurized stainless steel chamber where water and alkali solution are added and the temperature is kept at 350 degrees Fahrenheit. (6) Between the water, alkali, heat, and pressure working together circulating the corpse the reaction begins and completes the cremation…

In 1985-1990 we see that various scientists such as Kalle (1985), Vikar and Panesar (1987), and Hecker et al. (1990) had begun endeavors to develop more efficient alkali and sulfite processes. This was done by attempted by sparging with CO2 (the bubbling of inert gases in the liquid to remove dissolved gases) or installing a vacuum in the fermenter to control aeration. This method resulted in a 40% glycerol yield efficiency at concentrations of 230 g/L. (Kalle, 1985; Vikar and Panesar, 1987). A…

The process can take place in three parts. • Filtration – This process happens in the entire nephron system. When blood goes through and into the capillary at the beginning of the nephron, small molecules, such as glucose, urea, ions and water are cleaned out and passed through the nephron tubule. The larger molecules such as blood proteins, cannot fit through the capillary wall as they are too big, therefore they stay in the bloodstream. • Reabsorption – When the small molecules are cleaned…

INTRODUCTION Background The macrocyclic organic molecules Phthalocyanines (1) which are comparable to the naturally occurring porphyrin (2) ring systems shown in (Figure 1). The porphyrin molecule consists up of four pyrrole subunits which are associated in n-conjugation by methine carbons. 1 2 Figure 1: structures of phthalocyanine and porphyrins molcule The compound…

The Omnivore's Dilemma is a book which modified the way people looked at their food and also what they ate. In Chapter 8 “The Omnivore's Dilemma”, Michael Pollan explains that omnivores like the modern day American can eat just about anything, but the problem is that they are uncertain of what should be eaten. Americans obtain a variety of choices when in a supermarket, but do they recognize what is good for them? Michael Pollan also argues that the reason we experience so many diet fads is that…

which are vertical columns. They are organized by either Roman numerals but are now more commonly organized by numbers from one to eighteen which is referred to as the IUPAC system. The different elements falling under one similar group name are: Alkali metals (Group 1), Alkaline earth metals (Group 2), Rare earth metals (Group 3), Transition metals (Groups 4-7), other metals and metalloids (Groups 13-16), Halogens (Group 17), Noble gasses (Group 18). Lanthanides and actinides are not numbered…

solution lead to protonation or deprotonation of the ionizable groups. The first part of this lab was to identify the unknown AA #3 which contains an ionizable side chain by constructing its titration curve using standard acid solution and standard alkali solution. Titration curve of the AA around its buffering regions would expect to have regions of small slope. A blank water titration curve was also determined by measuring the amount of acid or base consumed in titrating water and for finding…

It is interpreted to extend southwards into the United States below the Williston basin and extends northeast into Nunavut and northern Quebec wrapping around the Archean Superior craton (Ansdell, 2005). The THO is the end result of the closure of the Manikewan Ocean (Stauffer, 1984) which resulted in the formation juvenile crust which was eventually accreted onto the Archean Superior and Hearne cratons as well as a number of smaller cratons including the Sask Craton (Lewry et al.,1994). The…

Basicity of Pyridine vs Pyrrole The lower the pKb value of a compound, the stronger a base it is. Since pyridine has a lower pKb value, it is a stronger base than pyrrole. In this example, we cannot use either the steric factor or inductive factor to explain their basicity. Instead, we have to look at the hybridization state of the respective nitrogen atoms. The nitrogen atoms in pyrrole and pyridine are sp2 hybridized because they satisfy the following two conditions: 1) the atom has at least…

Background Research Enzymes are biological catalysts, they have optimum pH values and temperatures, their activity is greatest while in optimum. Enzymes are also proteins, if the shape of an enzyme changes, it would no longer work. Enzymes are substances that fasten the chemical reactions in the human body. Enzymes are proteins that make up shapes in order to allow smaller molecules to fit into them to increase the chemical reaction rate. Although enzymes are made by living thing, enzymes are…
