Chemical Reactions Essay Examples
A chemical reaction is a popular term in the sciences. This refers to the processes that result in a transformation in which one or more substances called reactants, become one or more different substances, the products. Elements and compounds are the substances that undergo a chemical change to produce an end product. Most elements and compounds can be corrosive or explosive when mixed together. Therefore, you must mix the right amount of compatible elements or compounds to achieve the desired result.
You may need to read an essay on chemical reactions to know elements you can mix. An atomic or molecular transformation rearranges the constituent atoms of the reactants to create different substances as the products. Reading the right essay about chemical reactions will prevent any mishaps in your chemistry practical classes. This phenomenon is different from a physical change, which involves only a change of state or appearance, such as ice melting into water and water evaporating to vapor. During a physical change, the substance will remain the same irrespective of the changes involved. Knowing the basics through a chemical reaction essay will guide you on the effects of certain components.
Title: The Factors Affecting Enzyme Activity Speeds Problem: How do the factors of temperature, pH level, substrate concentration and enzyme concentration specifically and significantly alter the rate of enzymatic reactions? Background Information: Enzymes are critical to the function of human life. They are the controllers of all the chemical reactions within our bodies – they […]
Introduction: The purpose of this experiment is to measure the effects of changes in temperatures and pH on enzyme activity in skeletal muscle, particularly the activity of lactate dehydrogenase (LDH). LDH is a glycolytic enzyme which converts pyruvate to lactate in the following equation: LDH Pyruvate+ NADH ? ————? Lactate + NADThe reaction above can […]
Number Objective Rates of Reaction Define the term rate of reaction. Describe suitable experimental procedures for measuring rates of reactions. Analyze data from rate experiments. Students should be familiar with graphs of changes in concentration, volume and mass against time. Collision Theory Describe the kinetic theory in terms of the movement of particles whose average […]
Various chemical tests Identifying ketones and aldehydes are used In this experiment in order to Identify an unknown carbonyl compound. The tests used are: 2,4- dinitrophenylhydrazone test, Tollen’s Test, Benedict’s Test, Chromic Acid Test, aka Bordwell-Wellman Test, Schiffs Test, and Iodoform Test. These classification tests provide results based on color change or formation of precipitation, […]
Friedel-Crafts acylation of anisole with acetic anhydride was used in this experiement to synthesize 4-methoxyacetophenone with the use of a reflux apparatus. Friedel-Crafts reactions can be done by alkylation, which involves mixing an alkyl or acyl halide with a Lewis acid, or acylation, which is done with acid chlorides or anhydrides(Lefevre). Acylation was used because […]
I did this lab to find out the differences between chemical and physical changes. I also did this lab to learn the signs that would indicate the chemical reactions and physical changes. I needed to learn the odor change, color change, bubbles or gas, irreversible, temperature changes and finger prints. By the end of the […]
Metabolism comprises of a vital set of biochemical reactions that all Miming organisms require to sustain life. For a marathon runner, their physiological response to strenuous exercise depletes both their fats and carbohydrate storage in order to supply energy in the form of Adenosine Troposphere (TAP). TAP is the energy form that the human body […]
Introduction The high cost of bio-diesel, compared to petroleum-based diesel, is a major barrier to its commercialization. It has been reported that 60-90% of bio-diesel cost arises from the cost of the feedstock oil (C. C. Lai et al. , 2005). Studies showed the potential of waste-cooking oil (WCO) as a material for biodiesel production […]
