What Is a Chemical Reaction

You encounter chemical reactions all the time. Fire, respiration, and cooking all involve chemical reactions. Yet, do you know what exactly a chemical reaction is? Heres the answer to the question. Chemical Reaction Definition Simply put, a chemical reaction is any transformation from one set of chemicals into another set. If the starting and ending substances are the same, a change may have occurred, but not a chemical reaction. A reaction involves a rearrangement of molecules or ions into a different structure. Contrast this with a physical change, where the appearance is altered, but the molecular structure is unchanged, or a nuclear reaction, in which the composition of the atomic nucleus changes. In a chemical reaction, the atomic nucleus is untouched, but electrons may be transferred or shared to break and form chemical bonds. In both physical changes and chemical changes (reactions), the number of atoms of each element are the same both before and after a process occurs. However, in a physical change, the atoms maintain their same arrangement into molecules and compounds. In a chemical reaction, the atoms form new products, molecules, and compounds. Signs a Chemical Reaction Has Occurred Since you cant look at chemicals at a molecular level with the naked eye, its helpful to know signs that indicate a reaction has occurred. A chemical reaction is often accompanied by a temperature change, bubbles, color change, and/or precipitate formation. Chemical Reactions and Chemical Equations The atoms and molecules that interact are called the reactants. The atoms and molecules produced by the reaction are called products. Chemists use a shorthand notation called a chemical equation to indicate the reactants and the products. In this notation, the reactants are listed on the left side, the products are listed on the right side, and the reactants and products are separated by an arrow showing which direction the reaction proceeds. While many chemical equations show reactants forming products, in reality, the chemical reaction often proceeds in the other direction, too. In a chemical reaction and a chemical equation, no new atoms are created or lost (conservation of mass), but chemical bonds may be broken and formed between different atoms. Chemical equations may be either unbalanced or balanced. An unbalanced chemical equation doesnt account for conservation of mass, but its often a good starting point because it lists the products and reactants and the direction of the chemical reaction. As an example, consider rust formation. When rust forms, the metal iron reacts with oxygen in the air to form a new compound, iron oxide (rust). This chemical reaction may be expressed by the following unbalanced chemical equation, which may be written either using words or using the chemical symbols for the elements: iron plus oxygen yields iron oxide Fe O → FeO A more accurate description of a chemical reaction is given by writing a balanced chemical equation. A balanced chemical equation is written so the number of atoms of each type of element are the same for both the products and reactants. Coefficients in front of chemical species indicate quantities of reactants, while subscripts within a compound indicate the number of atoms of each element. Balanced chemical equations typically list the state of matter of each reactant (s for solid, l for liquid, g for gas). So, the balanced equation for the chemical reaction of rust formation becomes: 2 Fe(s) O2(g) → 2 FeO(s) Examples of Chemical Reactions There are millions of chemical reactions! Here are some examples: Fire (combustion)Baking a cakeCooking an eggMixing baking soda and vinegar to produce salt and carbon dioxide gas Chemical reactions may also be categorized according to general types of reactions. Theres more than one name for each type of reaction, so that may be confusing, but the form of the equation should be easy to recognize: Synthesis reaction or direct combination: A B → ABAnalysis reaction or decomposition: AB → A BSingle displacement or substitution:Â  A BC → AC BMetathesis or double displacement:Â  AB CD → AD CB Other types of reactions are redox reactions, acid-base reactions, combustion, isomerization, and hydrolysis. Chemical reactions are everywhere. Learn More What Is the Difference Between a Chemical Reaction and a Chemical Equation?Exothermic and Endothermic Reactions

Ever Wondered What It Would Be Like To Live During The

Ever wondered what it would be like to live during the Renaissance? A lot of people wonder the same thing. The term renaissance is derived from the French word meaning â€Å"rebirth. It is used to describe this phase of European history because many of the changes experienced between the 14th and 16th centuries were inspired by a revival of the classical art and intellect of Ancient Greece and Rome. The Renaissance time period is very different from modern day life in the United States. Although the way of life now is very different than it was back then, the Renaissance period had a very big influence on the modern society and the way people live today. Technology, marriage, warfare, jobs, and transportation are among the major things†¦show more content†¦Yet there are some similarities, marriages were also very different than they are these days. Marriages back then were arranged, which meant the woman didn t have a choice who she was going to marry because her family d ecided this for her. â€Å"Marriage in renaissance times was viewed completely different than marriage in today’s day and age. One difference is that marriage in the renaissance was often not built on love but would be arranged by the families. Many times as in the case of nobility, marriages were arranged as a way to reach social and political gain (Anderson).† People in the renaissance also believed that women were created by God with the sole purpose of serving and obeying men. After marriage, a woman’s body and possessions became the property of her husband. A man was supposed to consummating the marriage and transform his wife from a virgin to a woman, ideally with a pregnancy. Once a woman lost her virginity to her husband, the consummated marriage was permanent. This is very different from today because women have a choice of who they want to marry and marriage is hardly permanent. Also, widowers aren t as common now as they were then. This was because then, husbands were on average fourteen years older than the women. Warfare back in the Renaissance was very different than it is now but it has had a huge impact on the way people see warfare today. â€Å"In the Medieval period besieging armiesShow MoreRelatedCultural Observation Project Essay examples1473 Words   |  6 Pages Cultural Observation Project 2 Name: Location of Observation: Coastal Grand Mall, Myrtle Beach, SC Date: September 28, 2013 Youth 201-Section #B01 What I Have Learned?

Consumer Decision making Model Samples †MyAssignmenthelp.com

Question: Discuss about the Consumer Decision making Model. Answer: Introduction Consumer behaviour is the buying tendency of the people who agree to pay a certain sum of money in exchange of some product or service (Ashman, 2015). It is the study of how the consumers of a particular product or service seek, purchase, analyze and dispose of products and services. It is the psychology of marketing- the study is utilised to understand why consumers buy a product in the place of another similar product. Business organisations offer products or services so that they get money in return and grow the business even further. A business organisation operates in an industry or market of the specific product or service or business model that the company has adapted. In order to ensure that the product or service has a unique image in the company it has to device strategic plans, and understanding the trends or consumer behaviour is essential as it guides the company to develop, innovate, diversify etc in order to engage the customers they are targeting (Solomon et al., 2014 ). The strategies that the company formulates impact the customers of the company extensively. The strategies are a source of communication and regarding the products and services that the company is offering. It persuades the way the consumers imagine and perceive, the product and in turn influence the buying decisions (Sparks et al., 2013). The retailer that has been chosen is Amazon Australia; the company is a multinational organisation and is known for the customer centric approaches of business operation. The organisation is led by the visionary and transformational leader Jeff Bezos who has explained in several interviews that the focus of the company is to provide the customers with products and services which are at par with the needs and requirements of the company (Amazon.com, 2018). Consumer decision-making model A consumer avails a product or a service not always out of need or requirement as explained in the Maslows hierarchy of need theory. Apart from the necessities all other products that a consumer buys is based on various factors. Needs develop on the basis of the livelihood of a person and that influences the buying behaviour. Figure 1, shows the model of a simple process- there are input factors such as the efforts that the company makes and socio-cultural impact on the consumer initiates that process of buying behaviour among the people (Ashman, 2015). People get influenced by the marketing efforts of the company and also by the family and friends and other aspects of the society that the customer is in bound (Ashman, 2015). The Amazon website is known to be one of the most user friendly layouts where the customer exactly knows what to do in order to reach the desired product. There is also a list of promotional features in the home page that is cumulated by the website based on the previous purchases. The website tries to understand the preference of the account user and lists a number of items with promotional features. This is one of the ways of communication that the website has with the customers (Amazon.com, 2018). In order to buy a product from Amazons website it is mandatory to make an account with the website. Once you have provided your account details the company also communicates with the help of e-mail or sms. These are some of themarketing efforts of the firm that can influence the buying behaviour of the customer. For example, if a customer has previously bought cosmetic items from the website and the next time he or she logs in they are welcome with an offer on some of the items that the customer have in the wishlist, which may influence the customer in buying the commodity (Amazon.com, 2018). There is a feedback option of the products in the website where the previous customers can post about their experience with the product or the seller; this is also one of the ways in which the customers buying behaviour can be influenced. One of the disadvantages with online retailers have is that they lack credibility if the customer is not sure of the brand of product or the seller then they may be sceptical of buying the item right away. In that case, they will read the comments regarding the product and then make their decision. This is how the society influences the behaviour of buying from Amazon (Amazon.com, 2018). Needs and wants of consumers According to Maslows hierarchy of needs theory, a person has to be motivated to achieve something and these needs are to be attained in a sequence and some take precedence over another. The theory is explained in the form of a pyramid which sets the most basic needs right at the bottom taking a larger space, going upward is the psychological need and then comes the least important need for survival, which are the self-fulfillment needs (Kaur, 2013). The buying behavior of the consumers also can be categorized according to these divisions. Each of the categories is underlined by motivations such as necessity, urge of fulfillment, self-satisfaction as well as extrinsic motivational factors (Kaur, 2013). Recommendation The company should ensure that the product description is authentic and is a little descriptive so that there is little or no scope for miscommunication. Conclusion It can be concluded from the above discussion that consumer behaviour is dependent on marketing efforts of the company and psychological, social and cultural factors. These needs are categorised according to the nature of the product or service and are driven by several intrinsic and extrinsic motivations. References: Amazon.com. (2018).Home page.amazon.com.
