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
The plastic plate with a small hole was then inserted into the first groove from the top of the sensor box at a distance of 2 centimeters (20 millimeters) from the sensor. The readings of the Gieger counter were then taken after one minute. The same
Scientific research studies indicated that people who often drink tea in large amounts are susceptible to develop a painful bone disease called skeletal fluorosis. Its symptoms are joint pain similar to arthritis and bone loss similar to
In recent times, concrete has become a complex material, which has become difficult to understand. Throughout the years, it has been experimented in order to improve its strength. Materials such as flash, marble dust, and several cementitious materials have experimented with concrete in order to improve its strength and other properties.
The CuSO4 solution has the deepest blue color that absorbs more light than a solution of lower concentration, for example, Copper (II) acetate. Atomic Absorption Spectroscopy (AAS) technique is used to determine the absorbance of the solutions. Five standard
has had scientific backing with transform plate boundaries sliding past one another, resulting into land disturbances on areas around the transformed plates, an aspect considered as the greatest contributor towards the occurrence of earthquakes as contributed to by fracking. The
At this point there is an equal amount of both the acid and the base. As the titration proceeds, the point at which the colour of the solution that contains the indicator changes is called the end point (Levine, 2001).
The molar mass determination process requires complemented efforts of definite gas laws, especially Avogadro’s gas principles and Archimedes’ buoyancy laws. Archimedes laws facilitate determination of floating and sinking of an
Place 5 drops of the test reagent on the white spot plate then adds 2 drops of the unknown #703 sample. Stir the solution with a thin glass rod in order to mix the components and observe any color change.
Place 100 μl of the cold
Basically, the flame is used to atomize the sample so that radiation emitted is measured. Understanding the principle of atomic emission spectroscopy would require a brief description of the instrument used. This would offer us an insight on the principles involved in
Stir with a stirring rod slowly for some time. It is better to take the water at room temperature as cold water is inappropriate for dissolving salt. Cover the beaker.
9. Take the mixture of sand, salt and water, gently stir it again,
trations periods are greater than 0.5 gm/kW which translates to more than $3600 platinum per vehicle, less expensive methods like this one are perfectly welcome. Reducing the amount of platinum needed for anti-knock at the cathode is surely important to the economy.
Ionic bonding defines cohesive forces between atoms of different chemical elements because of ions of opposite charged that attract one another. The bonding forms between two elements such that atoms in one of the elements lose electrons from
The ideas on the regulation of protein synthesis in bacteria have mainly arisen from the studies of Perse Monod on the induced synthesis of B-galactosidase in E.coli. It resulted in the discovery of regulatory events to the transcription of DNA and the assemblage of functionally related genes into clusters called operons.
major target of the drug is to address the needs of the patients suffering from the cardiovascular diseases, who are always at a higher risk of stroke.2The drug was first approved in Japan in 2011, and has subsequently been approved in the USA by the Food and Drug
The common goal of scientific policies are to typically help the general public and protect them from any issues that arise in the sectors of health, environment and safety and though sometimes politics have a common interest
Acid rain can be prevented through a number of ways in future. According to Casper, acid rain can be prevented in future is by switching to sources of energy that emit low levels of carbon.3 Combustion of
According to Chemical Board Safety (2002), 167 serious cases of accidents had occurred between 1980 and 2001. In connection to this, the main aim of this paper is to analyse what should have been done to prevent the chemical explosion that occurred in T2
methods of crime suspect’s identification using DNA analysis and comparison of existing data from the integrated automated fingerprint identification system are not exhaustive because such information depends on their authenticity from the time of collection from the crime
The major component in anise oil has the chemical formula C10H12O. It is a hydrogen deficient component having less hydrogen atoms than would be required for every carbon atom to have the maximum amount of attached hydrogen
This lab report covers on the laboratory preparation of Cs [ICl2]; a polyhalogen complex containing cesium as the central atom, and iodine and two chlorine ions as the attached halogens. The main purpose of this experiment involved evaluation of a polyhalogen
Developing cost-effective and viable technology to prepare food color and how it is applied in foods has become a challenge as well as a daily need. In this experiment, the dye for the new drink will be developed simply by copying the color profile a beverage that has been colored artificially. The principle of absorption spectroscopy.
es) which are found in plants are classified under secondary compounds because their chemical synthesis has evolved more hence making such plants better adapted to local ecological niche. The plants that produce terpenes are mainly aromatic herbs that have pleasant smell and
The Red Curve shows the first half of the scan 0.00V to 0.80V and back to 0.50V.
The process is irreversible because the oxidation of ascorbic acid produces Dehydroascorbic Acid which is very unstable and it decomposes quickly before the reduction
It was established that the ethanol concentration of the unknown was 13.805 ± 1.31% w/v.
High concentrations of ethanol (ranging between 0.3 and 0.4%) in the blood often lead to fatal consequences that include death.
This was shown when a green flame appeared using the Belstein test, indicating the presence of unreacted alkyl halide. The presence of the C-Cl stretch in the FTIR spectrum of the product also indicated the presence of
Part three will illustrate the relationship between pressure and temperature. The results of these measurements will be used to derive the Ideal Gas Law.
From figure 1, we deduct that volume of a gas increases
The first edition of United States Pharmacopeial convention featured the preparations and drugs that were the best and also defined terminologies that facilitated communication among the physicians. These physicians were responsible for medication administration and prescription and the pharmacists who were preparing them.
ly leads to the chelate effect because reactions involving the formation of 1,2-diaminoethane increases the entropy of the system by escalating the disorder of the system. Changes that increase the entropy of a system increase the likelihood of a reaction taking place. Compounds
The chemical shift targeting each nucleus can be correlated to the chemical environment with the scalar coupling showing an indirect interaction between the individual nuclear that are mediated by the electrons found in the chemical bond and appropriate
Metal carbonates decompose on heating, liberating carbon dioxide from the long-term carbon cycle and leaving the oxide of the metal.
