Science

A Chemical Reaction is a process where reactants chemically combine to form new compounds, by rearranging atoms, which are known as products. The Law of Conservation of Matter states that atoms cannot be created nor destroyed.
A Decomposition reaction is a chemical reaction. It is used in airbags located in cars which within inflates less than a second due to an initial decomposition reaction producing nitrogen gas. It is important as there are decomposition reactions to occur because it provides immediate cushioning after car crashes hence saving many lives. It is also important since airbags are required to use few reactants it is needed to also give an effective protection at the same time and therefore sodium azide is used to produce 60L of nitrogen gas and moreover is able to fit inside of the steering wheel at the same time thus it is more effective. The use of sodium azide not only protects humans but it also does not produce any toxic chemicals to harm humans.
Decomposition works in airbags by the sodium azide powder placed inside the airbag chamber. When the car or vehicle undergoes a collision, three chemical reactions takes place, where sodium azide rapidly decomposes to form nitrogen gas and sodium metal, by a small spark which would heat the molecules of Sodium Azide which then makes it fall apart and produce a less toxic compound called nitrogen gas.
In this the Word Equation for this Chemical Reaction is: Sodium Azide(s) Nitrogen (g) + Sodium(s)
The chemical equation is:
2 NaN3 2 Na + 3 N2
In this reaction the reactant Sodium Azide is a chemical which is reactant to heat which is then therefore an endothermic reaction which gives off heat and so gets colder. It is also hence a non-spontaneous reaction because it does not occur naturally and energy is needed. The product in this decomposition reaction is Nitrogen gas, it forms…...

Chemical Conversion Processes

...CHEMICAL CONVERSIONS Acylation Acylation (rarely, but more formally: alkanoylation) is the process of adding an acyl group to a compound. The compound providing the acyl group is called the acylating agent. These are used to form aryl ketones. Because they form a strong electrophile when treated with some metal catalysts, acyl halides are commonly used as acylating agents. For example, Friedel-Crafts acylation uses acetyl chloride (ethanoyl chloride), CH3COCl, as the agent and aluminum chloride (AlCl 3) as a catalyst to add an ethanoyl(acetyl) group to benzene: The mechanism of this reaction is electrophilic substitution. Hydrolysis While solvolysis often refers to an organic chemistry context, hydrolysis is very common in inorganic chemistry, where aqua complexes of metal ions react with solvent molecules due to the Lewis acidity of the metal center. For example, aqueous solutions of aluminium chloride are acidic due to the aqua-aluminium complex losing protons to water molecules, giving hydronium ions which lowers the pH. In organic chemistry, hydrolysis reactions often give two fragments from an initial substrate. For example, the hydrolysis of amides give carboxylic acids and amines; the hydrolysis of esters give alcohols and carboxylic acids. Alcoholysis An example of a solvolysis reaction is the reaction of a triglyceride with a simple alcohol such as methanol or ethanol to give the methyl or ethyl esters of the fatty acid, as well as glycerol. This reaction is...

Chemical Kinetics

...biochemical reactions. The enzymatic reactions were looked at by the use of two comparable reactions of enzyme invertase and a acidic form of the reaction. The order of the nonacidic enzymatic reaction was zero order due to substrate concentration and due to the fact that the reaction was time dependent. It is also due to having large R2 value at 0.9932 for D run and a smaller R2 value at 0.9902 for C run. The acidic runs had a first order reaction, which had a lower R2 values at 0.9028 for run D and 0.9028 for run C. Also, the percent error in run C at 33.31% was found to be much lower than the percent error in run D at 55.77%, which mean the concentration of run C is more effective than run D. I. Introduction In this experiment the chemical kinetics of the enzyme catalyzed inversion of sucrose was studied. The reaction that we will study in this experiment is the inversion of sucrose, catalyzed by the enzyme invertase that is derived from yeast: The rate of reaction of this reaction was compared to the same reaction that is to be catalyzed by hydrogen ions. Enzymes make up an important class of proteins that are used to catalyze a wide array of biochemical reactions. The enzyme that was used to catalyze the reactions in this lab experiment was the enzyme invertase (β-fructofuranidase). The first to propose the basic mechanism for enzyme-catalyzed reactions was......

...introduction of contaminants into the natural environment that causes adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollution also has different components call Pollutants. (Wikipedia 2012) A pollutant is substance or energy introduced into the environment that has undesired effects, or adversely affects the usefulness of a resource. A pollutant may cause long- or short-term damage by changing the growth rate of plant or animal species, or by interfering with human amenities, comfort, health, or property values. (Wikipedia 2012) There are also different kinds of pollutants like greenhouse gases, pesticides, endocrine disruptors, petroleum and heavy metals. Carbon dioxide and methane are two of the most important of these gases, called greenhouse gases because they trap heat in the earth's atmosphere. This is already causing severe problems around the world and the situation will only get worse. The rising temperatures will likely lead to more severe weather events, which cause shifts in natural communities, and probably lead to greater species extinction rates, among numerous other effects. Pesticides are a broad group of chemicals that enable us to live more comfortable lives by and large, but whose main purpose underlies the central problem with pesticide pollution. They are all poisons. A lot of these chemicals will wash into our rivers and streams and cause direct toxicity to fishes, and may work their way up......

Chemical Reaction

...Chemical Reactions Types of Chemical reactions Lots of reactions take place around us in everyday life. Reactions are quit important in chemistry and in science generally. Chemical reaction is the changing of substances to other substances by the breaking of bonds in reactants and the formation of new bonds in products. There are different types of chemical reaction: 1. Combination reaction 2. Decomposition reaction 3. Single-replacement reaction 4. Double-replacement reaction 5. Combustion reaction Combination reaction is a chemical change in which two or more substances to form a new single substance. The reactants of most common combination reactions are either two elements or two compounds. The product a combination reaction is always a compound. Decomposition reaction is a chemical change in which one substance is broken down into two or more products. These products can be any combination of elements and compounds. It is usually very difficult to predict the products of decomposition reactions. Single-replacement reaction is a chemical change in which the atoms of less active element are replaced with atoms of elements which are more active. Usually the reactants are substance and element. Whenever one metal will replace another metal from a compound can be determined by the relative activities of the two metals. For predicting the products of this type of reaction we have the metal activity table, which is expressed above. Li K Ca Na Mg Al ...

Investigating an Enzyme Catalyzed Reaction

...Running head: LAB 5: INVESTIGATING AN ENZYME-CATALYZED REACTION Lab 5: Investigating an Enzyme-Catalyzed Reaction September 24, 2014 Principles of Biology 120.601 Mrs. Annemarie Duncan Abstract: (Burmania) This experiment was performed in order to examine ways in which a potato catalase enzyme reacts to various assays with differing variables. To do so a baseline assay (undiluted extract and room temperature H2O2) was used within the experiment with only one other variable changed in the other assays. These variables included a boiled, frozen and then thawed, and frozen potato extract and dH2O instead of the potato extract. It was noted that the temperature and or way the potato extract was prepared effects how the enzyme with the potato will react. Therefore the results of each assay varied, suggesting there is more than one way that a catalyzed reaction can occur. Introduction: (Burmania) The main purpose for this experiment was to explore how an enzyme catalase caused a reaction to catalyze through doing various assays using potato extracts. Enzymes are catalysts that are crucial in helping to speed up reactions, and catalase is a common enzyme found in almost every living organism that is exposed to oxygen. For this experiment, potatoes were used because they were previously known to have significant catalase activity. The potato catalase was mixed with hydrogen peroxide because the catalase helps to breakdown the hydrogen peroxide which helps......

Chemical Reactions

...Chemistry “Chemical Reaction and the PH Scale” Chemical reactions are the heart of chemistry. People have always known that they exist. The Ancient Greeks were the firsts to speculate on the composition of matter. They thought that it was possible that individual particles made up matter. As you might imagine, it's useful to be able to measure the acidity of solutions. Scientists have come up with the pH scale for determining the concentration of acid in a solution so we can distinguish between solutions with varying acidity. A Chemical reaction is the outcome of two or more elements together results in the formation of a chemical bond between atoms and compound. Chemicals react together due to participating atoms. The reason why atoms react with each other is to reach a state in which their valence shell is filled. Reactions occur at different speeds, they have different rates of reaction. There are some things that must be considered in a chemical reaction. There are a few things that decide the course and speed of the reaction. One thing about chemical reaction is that, there is now known that there are three types of chemical reactions. They are classified into three types: exoergic (exothermic), endoergic (endothermic), and aergic (athermic). In these cases, energy is supplied, but the different types of reactions initiate the energy differently. First of all, Exoergic, or exothermic, reactions release energy during the reaction. ...

Reactions Lab Report

...Purpose How do we determine the reaction type and write a balanced equation for chemical reactions? Background Discussion There are many kinds of chemical reactions and several ways of classifying them. One popular and useful method is to classify reactions into five major types. These are: (1) synthesis, (2) decomposition, (3) single replacement, (4) double replacement, and (5) combustion. Most reactions can be put into one of these categories. In a synthesis reaction, two or more substances (elements or compounds) combine to form a more complex substance. A decomposition reaction is exactly the opposite of a synthesis reaction. In a decomposition reaction, a compound breaks down into two or more simpler substances (elements or simpler compounds.) In a single replacement reaction, one element in a compound is replaced by a more active element. In a double replacement reaction, the positive ions of two different ionic compounds can be thought of as “replacing each other.” Most replacement reactions (both single and double) take place in aqueous solutions containing free ions. In a double replacement reaction, one of the products must be removed from the solution as a precipitate, water, or an insoluble gas. A precipitate is a solid that is produced as a result of a chemical reaction in solution. As the precipitate separates from the solution, the solution appears cloudy. In a combustion reaction a substance combines with oxygen, releasing a large......

...The Diels-Alder Reaction of Anthracene with Maleic Anhydride The Diels-Alder reaction is a member of a class of reactions called cycloadditions. The reaction involves three π bonds, two from the diene and one from the dienophile in a concerted reaction to form a six-membered ring. Since the reaction involves four π electrons in the diene and two π electrons from the dienophile, it is sometimes referred to as a 4 + 2 cycloaddition. Normal Diels-Alder reactions are favored by electron donating groups on the diene and electron withdrawing groups on the dienophile. The diene must be capable of achieving an s-cis conformation to generate the cis double bond in the cyclohexene product. Acyclic dienes may rotate around a single bond, but dienes locked in the s-trans conformation do not react. [pic] The purpose of this experiment is to form 9,10-dihydroanthracene-9,10-α,β-succinic anhydride by way of a Diels Alder reaction between anthracene and maleic anhydride, as shown in the reaction below. Anthracene acts as the diene and maleic anhydride functions as the dienophile. Xylene (dimethylbenzene) is used as a high boiling temperature solvent so that the reaction will proceed quickly. Melting temperature analysis will be used to characterize the product. Anthracene Maleic anhydride 9,10-dihydroanthracene- ...

Factors That Affect the Rate of Decomposition

...Factors the affect the rate of decomposition pH of soil The pH of the soil can affect the rate of decomposition as it directly affects the type and activity of the bacteria, fungi and other micro-organisms decomposing material. A highly acidic soil (0-7 pH) or highly alkaline soils (7-14 pH), it is not a ideal environment for the micro-organisms to grow in. It also affects the food the soil biota feeds on, as extreme pH can determine the availability of essential plan nutrients. Temperature of soil In general, reaction rates increase when a temperature is hotter. This is also applicable to the rate of decomposition. The explanation for this relates to enzymes; the microbes, fungi and bacteria which are often the decomposers contain many enzymes which help to effectively break down a living being rolling body. If there is a higher temperature, in the instance, in the soil, then the enzymes will make more successful collisions than they would at a lower temperature.This in turn causes them to decompose an object faster. However if a temperature is too high it will cause the enzymes to denature. Meaning the substrate will permanently change the shape and will not fit into the active site. Using the lock and key model we can see how denatured substances can cause less successful collision and a slower rate of decomposition. Moisture of Soil Decomposition is a process which needs oxygen - many micro-organisms are suppressed and cannot effectively decompose......

Anaerobic Decomposition

...perish along with it. If we consider any topic, we have to look at it from all the angles available. Though anaerobic digestion opens a whole new door to environmental preservation, it also closes others. There are drawbacks, but the benefits greatly outweigh them. Before I get into any detail about how wonderful anaerobic digestion is, I should explain how it works. It all starts with anaerobic bacterium. Eons ago, fossil fuels were created by the use of anaerobic microorganisms. They are one of the oldest life forms on Earth. They existed before plants started giving off large quantities of oxygen. This bacterium is also the same type of microorganism that creates natural gas today. Anaerobic decomposition differs greatly from aerobic decomposition in the fact that anaerobic decomposition happens without the need of great quantities of oxygen. Don’t forget that the planet is also running out of healthy, clean air for life forms to breathe. The anaerobic digestion process consists of three stages, each implementing the use of different bacterium. During this process, one must first define the ideal temperature; for mesophilic bacterium it is 98 degrees Fahrenheit or 36.7 degrees Celsius, but for thermoplilic bacteria, the ideal temperature is 130 degrees Fahrenheit or 54.4 degrees Celsius. At first, a group of microorganisms converts organic material to a form that a second group of organisms utilizes to create organic acids, but what happens to the solids left over? The......

Rates of Chemical Reaction

...Introduction It has been determined that the rates of chemical reactions are affected by temperature. This experiment is done to test the effect of five different temperatures on the rate of carbon dioxide production in yeast by measuring the fermentation rate. “The fermentation rate is measured in ml/min.” The purpose for performing this experiment is to understand the rate of fermentation of yeast cells which can be determined by measuring the amount of carbon dioxide produced at each temperature. Since there is no direct way to measure the carbon dioxide produced in the lab, an indirect method is used instead. The fermentation rate in this experiment is measured in ml/min which is the rate of carbon dioxide production that is measured over time spent in each water bath. Water will substitute for the carbon dioxide produced at the end of the experiment. The amount of water is measured in milliliters (by the graduated cylinder) will serve as an indirect method of fermentation rate because carbon dioxide is a gas which cannot be measured by means other than indirectly with this experiment. Carbon dioxide production was measured by measuring the volume of water at different temperature; 25°C, 35°C, 45°C, 55°C, and 65°C. The time was also recorded at which all the measurements were taken for the different temperatures. Materials and Method The materials used in this experiment was: Yeast culture (contains yeast and glucose in the form of molasses) Five fermentation......

...RFCC UNIT CHEMICAL USE AND PREPARATION 1. LIQUID PHOSPHATE (Water treatment) External treatment: Reduction and removal of impurities from water outside the boiler. In general, external treatment is used when the amount of one or more of the feedwater impurities is too high to be tolerated by the boiler system in question. (e.g. softening, deaeration, evaporation) Internal Treatment: Is the conditioning of impurities within the boiler system. Its purpose is to properly react with feed water hardness, condition sludge, scavenge oxygen and prevent boiler water foaming. Purpose of Internal Treatment: • React with any feed water hardness and prevent it from precipitating on the metal as scale. • Eliminate oxygen from the water and provide enough alkalinity to prevent boiler corrosion. Phosphate-dispersants / polyphate-dispersants (softening chemicals) - Reacting with the alkalinity of boiler water, these products neutralise the hardness of water by forming tricalcium phosphate and insoluble dispersant that can be disposed and blown down on a continuous basis or intermittently. - Phosphates react with Ca2+ and Mg2+ compounds in the feed water. Ca(CO3)2 (Calcium bicarbonate) entering the feed water reacts with NaOH to for CaCO3. Since CaCO3 is relatively insoluble, it tends to come out of the solution.
