Introduction Titration (volumetric analysis) is a method of quantitative chemical analysis to determine the concentration of an analyte (a substance to be analyzed). The titrant (a standard solution of known concentration and volume) reacts with a solution to determine the analyte’s concentration. The volume of...

What is Respiration? Respiration is the chemical process by which organic compounds release energy. The compounds change into different ones by exergonic reactions. There are two types of respiration: Aerobic, needs oxygen and releases a lot of energy; Anaerobic, which does not require oxygen but...

Introduction The p-block of the Periodic table consists of groups 13, 14, 15, 16,17 and 18. The elements in the p-block have their outermost electrons in the p-orbital of their shells, hence they are called p-block elements. The p-block consists of solids and gases, and...

The periodic table is the blueprint of everything, a chart that sorts every known element and catalogues ever fundamental unit of the universe according to it weight, creating the basis for chemistry, physics and other scientific field. Knowing if the periodic table is completed or...

Introduction We can clearly see the Periodic Table everywhere. It is one of the most important and successful chemistry discoveries to date. To make the completed and latest periodic table, there are a lot of scientists and chemists who have been involved. One of the...

Introduction The element copper is a necessity for humans, people need to have a small amount of copper in their diet. “On average, most people will eat and drink about 1,000 micrograms (μg) of copper per day” (Winter M. 2009). Copper is essential for a...

Heavy metals are very hazardous and have become a big concern for health practitioners over the previous years. Population growth, Industrialization, and urbanization have brought about the emergence of manufacturing industries to feed the growing population. Smoke and fumes from chimneys of industries have resulted...

Cultural diffusion is found heavily throughout the modern world, people in foreign nations have similar experiences as people in the United States despite being thousands of miles apart. Television and social media unite people in so many ways enabling cultural diffusion to occur yet in...

Introduction Denture plaque may be the cause of denture stomatitis or aspiration pneumonia in elderly people. A large number elderly population wore removable dental prosthesis and number of denture wearers increases with age. Polymethyl methacrylate is commonly used denture base resin because Polymethyl methacrylate has...

This lab involves the synthesis of an acrylic polymer. The reagents of hydroxyethyl acrylate, styrene, and butyl acrylate were reacted in a semi-batch process The product was then stored for one week before being crosslinked with a melamine-formaldehyde resin and a catalyst. The resulting coating...

Abstract The existence ofsecond-order structural phase transition in the SnSe at a pressure of10GPa has been proved theoretically. The calculation is performed using the plane-wave pseudopotential approach to density-functional theory within the local-density approximation (LDA) withthe help ofthe ABINIT software package. Theabrupt change inbulk module...

Discussion and Explanations Over the duration of this lab our group successfully learned how to use and analyze samples using the Spec 20. These instruments are intuitive to use, however there are also some common errors that can easily be overlooked. Once the Spec 20...

This case study is about the explosion of container containing nitric acid. On 2nd December, 2011, a graduate scholar was going to perform an experiment trial requiring the utilization of nitric acid. The students were working with nitric acid for the first time and no...

ALUMINIUM HYDROXIDEOCCURRENCE Aluminum hydroxide is a hydroxide salt type of aluminum. It is usually utilized as a medication, and can be found in acid neutralizers for the treatment of indigestion, gastritis, and peptic ulcers. It might likewise be utilized to lessen the retention of phosphorus...

Acrylamide (AA) has a toxic effect on both animals and human. The present study investigated the potential protective effect of silymarin (SIL), as an antioxidant against the toxicity of the AA in cardiac tissue. Rats were divided into four groups as follows: The control, AA,...

Introduction Electric propulsion has taken over the chemical propulsion system in space travel due to its high efficiency with less amount of propellent. We are all aware that Xenon is used as a propellent for the plasma thrusters. This article mainly deals with discussing an...

Enhancing executaion has gone up against another desperation as of late as governments confront mounting requests on open consumption, combined with calls for higher-quality administrations and an open progressively unwilling to make good on higher regulatory expenses. This has driven governments to center around the...

Nanoporous gold is basically made by selective decomposition of silver from silver-gold alloys. Due to its excellent conductivity, high surface area to volume ratio, chemical inaction, physical stability, easily tunable pores, and plasmonic properties which has taken place a huge field in the field of...

Introduction Nowadays, there are various chemicals being exposed to human naturally or synthetically. It can be present in pharmaceutical products, cosmetics, pesticides and even foods. Few of the chemicals present in typical daily product may be cancer inducing chemicals that can be dangerous for human...
