Chemistry Essays

Chemistry essays are different from those who are more related to creative writing. They should be based on critical thinking, logic, and proper evaluation. Sometimes these essays are built on solving chemical equations and other problems. You need to have the solid theoretical background to prepare homework which deserves the highest grade. When students cannot cope with the tasks alone, they seek help at writing service. Our company is one of the best in this specialization. We do not only offer free samples on any topic but help with preparing the entire work within the quickest time.

You can find these chemistry samples only at this category of our website. We share the best papers prepared by our qualified experts to attract more customers.

MDMA: Biochemistry and Medical Indications

Introduction. MDMA (3,4-methylenedioxy-N-methylamphetamine), known by the street names Ecstasy, E, X, or XTC [1] is a semisynthetic entactogen of the phenethylamine family. MDMA is a ring substituted amphetamine derivative [2] structurally related to the hallucinogens and the stimulants, whose primary effect is the stimulation of secretion as well as inhibition …

Radioactive Decay

One basic reaction in nuclear chemistry is the process of radioactive decay. In radioactive decay, an atom of one element emits an alpha or beta particle to become an atom of a different element. In alpha decay, the atom emits an alpha particle composed of two protons and two neutrons …

School of Process, Environmental and Materials Engineering

Executive Summary: In the production stage of ethylene oxide, it is normally stored in special automated chemical process plants. Ethylene oxide has been produced since the early 1900s, originally by the reaction of ethylene chlorohydrin with base and in recent years more commonly by catalytic oxidation of ethylene. It has …

Environment Economics: Acid Rain

When an atmosphere witnesses the emissions of nitrogen oxides and sulfur dioxides, acid precipitation or acid rain occurs in the environment. Subsequently, water droplets absorb the abovementioned emission, which undergoes various chemical transformations in the clouds. Rain, mist, hail, dry dust, snow, etc. are some of the forms that are …

Extraction of Copper from Oxidised Copper Ore

Aim: To analyse how copper is obtained from oxidised copper ore using the processes of leaching, solid-liquid separation, displacing and electrowinning. Method: Refer to ‘Extraction of Copper from oxidised Copper Ore’ document pages 1-2 Results: Leaching: The blue particles in the copper ore which is copper was dissolved in the …

Tea Flavonoids (Phytochemistry)

Due to the high cost of health care services, many natural products have been discovered and undergone clinial trials. These are called phytochemicals. These chemicals were oftenly used and offered to those who prefer conventional and alternative medicine until potential health benefits were offered worldwide. Green tea has the highest …

The Effect of Exercise on Lactic Acid in Muscles

For decades it has been a common belief in sports training that lactic acid causes fatigue and that an athlete should train below the “lactic threshold.” Other beielfs about lactic acid in the past are, it builds up in your muscles and makes your muscles burn, lactic acid buildup …

Analysis of Soda Ash and Carbonate-Bicarbonate Mixture

Abstract A standard acid solution like HCl can be used as titrant for the analysis of both soda ash and a carbonate-bicarbonate mixture. In the analysis of soda ash, the volume needed to neutralize the soda ash is used to compute for its alkalinity, in this experiment we obtained a …

Chemical Equilibrium

A. Iron- Silver Equilibrium The first part of the experimentation focuses in the iron-silver system. Silver nitrate (AgNO3) was added to ferrous sulfate (FeSO4) shown in this equation: 2AgNO3(l) + FeSO4(l) Ag2SO4-(aq)+ Fe(NO3)2(aq) The additon of AgNO3to FeSO4 equilibrium had an effect on the equlibria. Though no precipitate was formed …
