Primarily, as one might expect the available literature for ionic liquids in multicomponent reactions are highly functional in nature. The essential objective being to catalog the before, and after stages of the reaction, and the variety of chemical species that can be derived from such solutions.
Epstein Barr Virus, commonly referred to as ‘EBV’ belongs to the herpes virus family. It is one of the most commonly found human viruses. This study used the samples of tonsils from patients suffering with the chronic tonsillitis. So, a total of fifteen tonsillar tissues were obtained from eight donors.

des calculation of the radiance balance (heat fluxes, heat conduction) and mass balance (freezing, snow accumulation, melt, evaporation) for the three chosen glaciers in Nepal. It was found that the glaciers in the humid areas show the increased mass wastage comparing
Basically, PVC is classified into broad categories which are thermoplastic and thermosetting resins.
PVC is linear in structure which comes about through head to tail addition of molecules to a polymer chain. These monomer
Reportedly, there is a significant overlap between therapeutic and toxic drug concentration ranges such as fungal-derived immunosuppressive drugs, Cyclosporin A also known as Prograf® and FK506 known as Tacrolimus ® commonly used after soft organ transplantation and in the treatment of autoimmune disease.
According to Hansen (15), the information provided by these groups link the origin of Ag to some stars. For instance, Crawford et al. (1998) claim to have identified Ag in seven stars. In relation to their assertion,
Organic chemist’s ability to predict the importance of new compounds before they are synthesized is still rudimentary (Wyatt and Warren 661). The possible medicinal uses of natural products with their diverse molecular structure have been and still are the subject of
The author states that the formula of Magnesium can be predicted with the use of atomic theory, which leads to the electron structure of Magnesium and Oxygen atoms. The aim of the experiment is to compare the empirical formula of Magnesium Oxide developed after the experiment with the formula developed during the experiment.
There is no recommended dietary intake (RDI) for fibre as such in Australia. However, the Australian Department of Health has among its dietary goals for Australians an increased intake of fruit, vegetables, bread and cereals, all of which are sources of dietary fibre. The greatest amount of dietary fibre in wheat is in the outer layer or bran.
r, energy could shift between forms or undergo inevitable conversion from electricity to heat such as the kind of energy transformation taking place in a calorimeter. Following the law of conservation of energy which states that energy is given neither to generation nor
Grignard reagents are carbanions with counterions of Mg2+ and Br-. This reaction was discovered by Victor Grignard and follows the following basic scheme (Clayden, Geeves and Warren):
Grignard reagents undergo several reactions, the most common being the
Further, there was also need to understand the change of color occurring at the preparation transition. Considering that there are various steps involved during synthesis, the knowledge about the color changes serves significantly in
Generally, the addition of co-solvent is capable of increasing the solubility of hydrophobic substances such as the paracetamol drug according to recent studies. Organic solvents like alcohols are completely miscible with
A micro-emulsion may also be formed.
As seen in the results, C1 has the highest value of droplet size before and after dispersing. Furthermore, it also has the highest creaming percentage, and by extension a high chance of coalescence. Addition of a second emulgent,
Many toxic, flammable, hazardous and explosive substances are used in the processing of manufacture and operation at the petrochemical plant. Therefore, it is vital that the management recognizes the risks and hazards and possibly come up with ways through which to minimize the risks.
This will raise the milliliters or the volume of the titrant added, decreasing the molarity or making it too low. That is the reason why one want it a very light color and not a dark rich color.
The other source of error is the use of impure
The hepatic ducts, the cystic duct and common bile ducts, are all involved in this process. Bile salts trapped in the leads to inflammation within the gallbladder, ducts, or rarely the liver. Attacks from gallstones mostly result from
Molecules at S0, S1, and S2 have distinguishing characteristics. It can also be studied in an ESP spectroscopy. It involves electronically exciting and quenching a molecule.
Polarization helps in identification of
Positional isomers of xylene were scanned and concentration of the unknown was linearly determined through the obtained peak responses.
Fourier Transform Infrared (FTIR) is an analytical technique used primarily to identify compounds based on the
Effective diagnosis and subsequent treatment glucose level borne diseases such as diabetes is dependent on proper monitoring and maintenance. The paper will explicitly discuss amperometric glucose sensors ad a biomedical device that integrates electrochemical
(b)Yes. The reaction between Barium hydroxide and Nitric (V) acid will complete because the Nitric acid in the reaction reacts and completely dissociates to form Hydroxyl ions in solution. Hence due to its complete dissociation; the reaction is termed
In the paper, researcher presents the graph which shows the number of collisions with a particular energy for two different temperatures. The study would aim at answering these research questions: Which is greater temperature, T1 or T2? What does this graph tell you about the temperature dependence of the rate of a chemical reaction?
Most of the biopolymers (but not all) and some polymers obtained from the fossil fuels are biodegradable. Some biopolymers and most of polymers from fossil fuels are not biodegradable (Babu, OConnor, and Seeram 1).

The Stabilization wedge Game aims at reducing the projected carbon output by roughly 8 billion tonnes per year by the year 2055. This will entail using energy wedges to accomplish the stabilization triangle. Each wedge will represent a reduction of one billion tonnes
structures in about all biological processes indicates the need for understanding the factors that oligomerization and coiled coil folding in details. Some studies have addressed the unresolved and important questions related to the why presence of specific
The major observation obtained upon this comparison is that the fresher the egg, the more the salt needed to make it float and conversely, the older the egg, the less the salt needed. A fresher egg requires a higher density solution for it to
PVA is both degradable and soluble thus making it possible to be chemically decomposed to form intermediate products that are easier to dispose (Gnanou & Fontanille 23).
Polyvinyl Alcohol is used in making other polymers such as Polyvinyl Butyral. These polymers can be used
Moreover in this experiment the role for internal standard is negated because the standard shows linear response with increase in concentration. Further internal standards are used in case there is a possibility of losses during extraction of samples etc. In this case there is

The Projects in this course require special materials. Some of these materials are found in the Chemistry 1 Lab Kit and some will need to be provided by you, the student. Before doing a project, gather all the items you will need for that specific project
Hypothesis is usually explained as something which a person infers before actually/practically performing an experiment or doing something while on the other hand, observations is what a person observes/sees or experiences after live experience or watching
Ceramic Raschig ring has high surface area and moderate surface area as a result of its structure that is cylindrical hollow, therefore it is applicable as microorganism’s solid support, in which greater rate of mass transfer is attainable. In this report, the characteristics of hydrodynamic which include: material density, bulk density, etc.
The experiment has various application both in the laboratory and industrial applications. Drug manufacturing firms, for instance, use the procedure to test for the presence of anti-acid in drugs. The titration involves complex reactions where molecules or ions are formed when metals ions react with ligands or complexing agents which represent either one or more molecules.
The cuvettes are then placed into a spectrophotometer. They are oriented in such a way that their smooth sides lining face the light source to enable easy penetration of light through them. Multiple trials were then performed
