...Chemistry and Society Chemistry is in everything from a single element to complex compounds. It affects most every aspect of life in a person life and in society. Chemistry is involve with the medicine that a person take, the gas that they put in the tank of their car, the clothes that they put on for work, and to the food that they put in for nutrition. However, how does all that work to the betterment for them is due to the accuracy and precision of the measurement that chemist have come to find. The definition per the dictionary.com for accuracy is “the condition or quality of being true, correct, or exact: freedom from error or defect” (Dictionary.com, 2011). In addition the word precision can be interchangeable with the word accuracy so when a chemist is formulating a new compound they use measurement that is precise and accurate. However the difference between the two words is that accuracy is that getting close to the actual answer whereas precision is getting the same result every time and that it is reproducible and getting the same answer each time (Rutledge, 2010). Chemist use measurement everyday when they are working to find new stuff but even the everyday person uses these same measurements to do everyday work. Three types of measurement that a person might use are length, weight, and volume. In today society a carpenter might use all three from cutting the material, weighing out load limits, and the volume of a pool that they are installing. Most people would...

...Chemistry and Society CHM/110 Chemistry Is Everywhere Humans are surrounded by chemistry. Every product one uses on a daily basis is linked in some way shape or form to chemistry. Food, clothes, electronics, vehicles and medicines are all made up of molecules of elements. Through chemistry these elements were combined to form alloys, plastics, fabrics, liquids and gases that make up these products. Chemistry, like other sciences, relies on accuracy and precision in order to remain a reliable source of knowledge and a means for advancement of various aspects of human life. This paper will discuss the importance of accuracy, precision and the scientific method in chemistry and how these affect the lives of the average humans. Accuracy and Precision Accuracy and precision are paramount in the realm of chemistry but it is important to note that even though these two things are related they are different. According to Merriam-Webster (2012), accuracy is the degree of conformity of measure to a standard or true value. For example, if one is taking a drive that is known to be 5 miles and their GPS reflects a distance 4.9 miles travel the GPS is accurate to within one tenth of a mile. While accuracy and precision reflect how close a measurement is to a standard or true value, precision differs in that it is a reflection on how reproducible these measurements are. For example, if the same GPS from above measures 4.9 miles each time for 5 separate time then it is a reflection...

...Chemistry and Society (Name) CHM/110 Due Date Instructor Chemistry and Society Chemistry is an important part of our society. It is used for manufacturing the products we use, medicine, and just about every other aspect of our lives. This document will discuss how society depends on the accuracy and precision of measurements, the difference between accuracy and precision, and compare and contrast accuracy and precision of different types of measurements used in our daily lives. Accuracy and Precision Since the bulk of this discussion is about measurements, we will start off by discussing the difference between accuracy and precision in that context. When making any kind of a measurement, we need to be able to get as close as we can to any certain number. The question often asked is, how close to the actual number can we get? If we can get close that number that would be considered accuracy. When we think about precision, it is a different concept. Once we have been as accurate as we can be with our measurement, precision would be how many times we can achieve that measurement. Can it be duplicated? Society Dependence on Accuracy and Precision When we think about all of products available in the open market, we, as consumers, expect consistency in the products we buy on a regular basis. For example, Diet Coke is product a lot of us love to consume on a regular basis. We expect that soft drink to have a certain taste and not be flat. If we were to buy it...

...Chemistry and Society Accuracy and precision are used for measurements. The term accuracy means to have the exact value. The term precision means to be comprehensive and exact. The accuracy of a value is the measure of how closely the results agree with a true or accepted value. Precision of a value is the measurement of the reliability of the experiment. The differences are within the definitions, it all depends on what you are looking for within the results of a test for the proper use of these two units of measurements. Society depends on the accuracy and precision of measurements for products sold by the retail industry, such as a gallon of gasoline, a bushel of corn, or a liter of bottled water. These measurements have to be precise and accurate when it this relates to how farmers sell their products such as wheat, corn, milk, peanuts, and cotton, by weight and or in a bulk sale. Like food products gasoline, water, oil, and several other liquid goods are sold in quantity and if the measurements are not accurately sold per gallon then the United States government will not retain a profit from the barrel of gasoline, water, oil, and several other liquid goods that are purchased from other countries. I would have to say that this really is about supply and demand and the ability to generate a profit from the accuracy and precision of the weight and how much to sell an item for in most situations. Other ways society depends on the accuracy and precision of measurements...

...Chemistry in Life and Society Chemistry in Life and Society Chemistry is an important aspect of life and everything involved in it. From the precise measurements used in baking cookies and cakes to the cleaning agents used to clean the windows your little one smudges their fingers all over! Precise measuring when baking is essential. If one puts too much of one chemical it can throw the whole dish off and make it inedible. Many foods are also flavored with artificial flavoring and those are also chemicals as well. Chemicals affect the daily lives of everyone although some do not even realize it. Society depends on the accuracy and precision of measurements in many different areas. From filling up at the gas station to buying a gallon of milk. In everyday life accuracy and precision are usually thought of as interchangeable, but these two terms have crucial differences. Precision is a group of measurements that are close to each other, but they are not necessarily accurate. Accuracy of a measurement is how close the measured value is to the accepted value. In science “scientific numbers are reported so that every digit is certain except the last, which is estimated” (Tro, 2009, pg.14). Accuracy and precision is presented daily in life. When people play darts depending on which game they are playing one wants to be precise. With each throw of a dart one gains points for the precision in where the dart lands. People often rely on the accuracy of measurements...

...CHEMISTRY IN LIFE Charles Barker CHM/110 7/6/2015 Subhashis Nandy Introduction When living in a world such as ours, chemistry plays a large role in how society interacts. Chemistry can be viewed from many different angles because of its dynamics when dealing with the nouns of life (People, places, and things). With people, chemistry is how he or she connects to their social conformity. With places, chemistry is the structure and atmosphere that brings about the culture to the arena. With things, chemistry is the accuracy and measurement that brings the degree of closeness to the true value of its quality. In this paper, one will cover chemistry in terms of accuracy and precision, the relation to scientific methods, and how these methods can be applied to present and future lifestyle. Accuracy and Precision Accuracy and precision are close in comparison. In the field of chemistry and science, the difference of the two is that accuracy is the closeness of one or more measurements are to the correct answer. Precision on the other hand is the closeness of measurement to one another. It can also be referred to as the ability to recreate the same or similar results many times over. The differences of the two are within their meanings. The dependency of the situation will lie within the results of the diagnostics ran for the proper use of the two units of measurements.

...The Revolution of Chemistry Over the last few centuries the field of chemistry has made great strides. Humans have been experimenting and reaping the benefits of this field for millenniums, yet never had a great understanding it’s fundamentals until the chemical revolution. By the 16th century there had been many advances in the field later to be known as chemistry; smelting and refining of metals, the production of glass ware, pottery and dyes, the development of explosives, artists’ materials, and medicines (Butterfield, 191). Despite the production of these materials, they are not enough to be attributed to a science. As Butterfield suggests, the results of early chemical experiments lacked “adequate intellectual framework which on the one hand embrace the observed data and on the other helps to decide at any moment the direction of the next inquiry” (191). There is no better example of unorganized study than that of alchemy. Although Jensen cites alchemy as being a pillar of modern chemistry, Butterfield suggests it took away from the progression of chemistry into a modern science (191). To understand modern chemistry, we must first examine the origins of it. One of the key terms in chemistry is “elements.” This term was first used by Plato to describe matter. Soon after, Aristotle summarized the theories of earlier philosophers and developed the view that all substances were made of a primary matter. Aristotle defined an element as “one of those bodies into which...

Chemistry, biology, materials science, and genetics to analyze clue found at the scene of the crime, on the victims or in the bodies of the bad guys. Forensic Chemists go into a case with many unknow pieces of the crime scene they need to analyze to determine the nature of each sample. Most Forensic Chemists work in a lab. It is rare for private labs to do this kind of work so most of the time these labs are associated with Local, State, or Federal law enforcement agencies. From local Medical Examiner’s labs to state of the art FBI labs, Forensics Chemists often provide the strongest evidence in court against the defendants. They have many different types of test and methods they use to figure out what the samples mean. Each crime scene brings new types of clues and samples so a Forensic Chemist must always be thinking of ways to analyze the evidence. Some of the more common test for optical testing, X-ray spectroscopy, UV, and infrared. For separations analyses, HPLC, gas chromatography and thin-layer chromatography.

...fourth most abundant element by mass. The other major elements are sulfur and nickel. While iron is ingrained in most minerals, the primary iron is haematite. Nonetheless, iron is found engrained in other minerals such as taconite (Royal Society of Chemistry). Iron is produced commercially by heating the iron ores with carbon and limestone. The initial process results in an intermediate known as pig iron. Pig iron contains approximately 3% of carbon and other contaminants. It is utilized in the production of steel. The annual production of crude steel approximately about 1.3 billion tons (Royal Society of Chemistry). Pure iron crystals have a very soft texture.
