and oil. It best known for the brilliant reds that its salts give to fireworks and flares. It used for producing ferrite magnets and refining zinc. It can be also used for the production or manufacture of color television picture tubes. Strontium chloride hexahydrate is an ingredient in a toothpaste for sensitive teeth. Strontium was discovered in 1790 by Adair Crawford, an Irish chemist. Strontium is named after Strontian, a village in Scotland. It was identified as an element the next year…

In the production process, the polymer plastic will has Polyvinyl chloride toxic can cause serious pollution of air, water and land. Cycle can affect the natural environment.

Lake Huron as a “cost saving measure.” The river is polluted with lead from older, now defunct industrial factories which specialized in products that contain harmful byproducts. One of the water-purifying agents used in the Flint River is ferric chloride which has an effect on naturally occurring bio-matter in water, increased corrosiveness. This allows metals, such as lead, to be easily dissolved thus increasing…

Neutrinos are one of the most abundant particles in the universe second only to photons, yet they are one of the most elusive particles known to man. The neutrino is essentially a near massless subatomic particle possessing a neutral charge. Neutrinos scarcely interact with normal matter as a consequence of having a neutral charge and a mass of almost zero. There are three flavors of neutrinos: electron, tau, and muon; many neutrinos oscillate between these flavors. Neutrinos can be produced in…

There are five common ways to predict the product of chemical changes. They are synthesis (composition), decomposition, single replacement, double replacement, and combustion. Each can be used for different types of problems based on the equation of experiment presented to you. They can also be found using observations throughout the experiment. You use these base guidelines to write a well balanced equation with physical states and all of the reactants and products that are produced. Our…

heating process , we could see the colour of the solution was changing from blue to black slowly. Not only that , but black precipitate settling at the bottom of the beaker.

Silver nanoparticles have unique antimicrobial properties. They have a variety of applications: diagnostics, wound healing, pharmaceuticals, etc. These nanoparticles destroy bacterial cells walls and interrupt membrane integrity by their electrostatic attraction to the negatively charged bacterial cell walls [10]. Metal nanoparticles are usually synthesized by chemical techniques which is costly and highly toxic. Currently, there is a growing demand for alternative methods that would limit the…

it is C 5 ppm (7 mg/m³) and in OSHA PEL it is C 5 ppm (7 mg/m³). These measurements show that the limit to which a person can safely remain exposed to hydrochloric acid is 5 parts of hydrogen chloride per million parts of air which is measured in ppm or it can also be said as 7 milligrams of hydrogen chloride in every cubic meter of air (mg/m³). NIOSH REL is a term that comes from the National Institute for Occupational Safety and Health where recommended exposure limits also known as RELS are…

Purpose: We already knew that the chemical properties of each pure substance are not are not changed after separation in a mixture. The key to find a physical property that one part of the mixture does have but the parts of the mixture doesn’t. In magnetism a magnetically susceptible material is extracted from a mixture depending on a magnetic force. Filtration is separation of an insoluble solid and a liquid. Filtration depends on solubility, the filtrate is the one want to keep (liquid) and…

(b) State and explain if a chiral tertiary halogenoalkane would produce an optically active alcohol upon hydrolysis? Solution (a) benzyl chloride:  Comment: There are two types of nucleophilic substitution reactions. Students need to identify the correct type first before describing the mechanism. A benzylic carbocation is a very stable carbocation, more stable than a tertiary…
