Chemical Change Definition in Chemistry
A chemical change, also known as a chemical reaction, is a process where one or more substances are altered into one or more new and different substances. In other words, a chemical change is a chemical reaction involving the rearrangement of atoms. While a physical change can often be reversed, a chemically change typically cannot be, except through more chemical reactions. When a chemical change occurs, there is also a change in the energy of the system. A chemical change that gives off heat is called an exothermic reaction. One that absorbs heat is called an endothermic reaction. Key Takeaways: Chemical Change A chemical change occurs when one substance is transformed into one or more new products via a chemical reaction.In a chemical change, the number and type of atoms remains constant, but their arrangement is altered.Most chemical changes are not reversible, except via another chemical reaction. Examples of Chemical Changes Any chemical reaction is an example of a chemical change. Examples include: Combining baking soda and vinegar (which bubbles off carbon dioxide gas)Combining any acid with any baseCooking an eggBurning a candleRusting ironAdding heat to hydrogen and oxygen (produces water)Digesting foodPouring peroxide on a wound In comparison, any change that does not form new products is a physical change rather than a chemical change. Examples include breaking a glass, cracking open an egg, and mixing sand and water. How to Recognize a Chemical Change Chemical changes may be identified by: Temperature Change - Because there is an energy change in a chemical reaction, there is often a measurable temperature change.Light - Some chemical reactions produce light.Bubbles - Some chemical changes produce gases, which can be seen as bubbles in a liquid solution.Precipitate Formation - Some chemical reactions produce solid particles that may remain suspended in a solution or fall out as a precipitate.Color Change - A color change is a good indicator that a chemical reaction has occurred. Reactions involving transition metals are particularly likely to produce colors.Odor Change - A reaction may release a volatile chemical that produces a characteristic scent.Irreversible - Chemical changes are often difficult or impossible to reverse.Change in Composition - When combustion occurs, for example, ash may be produced. When food rots, its appearance visible changes. Note a chemical change may occur without any of these indicators being observed. For example, the rusting of iron produces heat and a color change, but it takes a long time for the change to be evident, even though the process is ongoing. Types of Chemical Changes Chemists recognize three categories of chemical changes: inorganic chemical changes, organic chemical changes, and biochemical change. Inorganic chemical changes are chemical reactions that dont generally involve the element carbon. Examples of inorganic changes including mixing acids and bases, oxidation (including combustion), and redox reactions. Organic chemical changes are those the involve organic compounds (containing carbon and hydrogen). Examples include crude oil cracking, polymerization, methylation, and halogenation. Biochemical changes are organic chemical changes that occur in living organisms. These reactions are controlled by enzymes and hormones. Examples of biochemical changes include fermentation, the Krebs cycle, nitrogen fixation, photosynthesis, and digestion.

The Effects of Roosevelts Worst Mistake - 890 Words
One of Rooseveltââ¬â¢s [most fatal] mistakes occurred before he was even inaugurated into office. His mistake was the fact that he didnââ¬â¢t listen to Herbert Hooverââ¬â¢s advice. Between Rooseveltââ¬â¢s election in 1932 and his inauguration on March 4, 1933, Hoover sent Roosevelt letters and scheduled meetings to tell him what he thought about Rooseveltââ¬â¢s New Deal plan. Herbert Hoover believed that the origins of the Depression were international, while Roosevelt believed they were local. For this reason the New Deal focused primarily on domestic reforms. Hoover believed that international affairs should take precedence, and he didnââ¬â¢t hesitate to tell FDR this. He suggested a return to gold-based currency and to balance the budget. Franklin D. Roosevelt ignored all of Hooverââ¬â¢s suggestions and started implementing his New Deal policies as soon as he entered office. Roosevelt was not blind to the effects the international crisis had on the Unites States, but he didnââ¬â¢t want to restrict his freedom as president by committing himself to othersââ¬â¢ ideas to fix it either. His first priority was to address the problems in the United States, and as a result his first term in office resulted in very few successes in fixing the problems abroad. [] Rooseveltââ¬â¢s New Deal had many flaws. One of these was the Silver Purchase Act of 1934.

The Grapes of Wrath- Symbolism Essay Free Essays
Symbolism Symbols are often used to represent bigger ideas and concepts in a novel. In The Grapes of Wrath, there are many symbols to represent the lives of not only the Jode family but the migrants as a whole. Steinbeck uses the symbols of the dust and the turtle to show the struggles of the migrants and how they overcame all odds, revealing the only hope the migrants had to survive the harsh trek cross country was perseverance. We will write a custom essay sample on The Grapes of Wrath- Symbolism Essay or any similar topic only for you Order Now The dust is the first significant symbol Steinbeck uses to represent the migrants and their struggles. As the dust filled the air in Oklahoma, families watched their lives settle to nothing along with the dust, ââ¬Å"The men were silent and they did not move often. And the women came out of the houses to stand beside their menââ¬â to feel whether this time the men would breakâ⬠(3). The dust is symbolic of the migrantââ¬â¢s lives eroding to nothing. It represents not only mother natures roll in the horrible tragedy of the crumbling families, but also represents the banks and large plantations that took over the small and venerable families and farms just like the dust engulfed their homes. Though the migrants went through so much with losing their farms, homes, and lives, they still stood strong and found a way to keep moving forward, ââ¬Å"After a while the faces of the watching men lost their bemused perplexity and became hard and angry and resistantâ⬠(3). The migrant families overcame their struggles with the dust over taking their homes along with all of the other struggles they faced, and they moved west for a new life. On their journey west, the migrants faced many challenging obstacles that they had to persevere through. Steinbeck uses the symbolism of the turtle to represent the stubborn migrants fighting their way west, ââ¬Å"And over the grass at the roadside a land turtle crawled, turning aside for nothing, dragging his high-domed shell over the grassâ⬠(14). The turtle was set back by both nature and man on his journey across the road, just like the migrants were on their long trek westward. The turtle faced a red ant, barely escaped death by a car twice, and had to struggle with rough terrain along with flipping himself upright after being flipped over by the front wheel of a ruck. Like the migrants overcoming sickness, death, car problems, money shortage, unfair merchants, and lack of work, the turtle also overcame all of his challenges and setbacks and continued to persevere on his path, ââ¬Å"Its front foot caught a piece of quartz and little by little the shell pulled over and flopped uprightâ⬠¦ The turtle entered a dust road and jerked itself along, drawing a wavy shallow trench in the dust with its shell. The old humorous eyes looked aheadâ⬠¦Ã¢â¬ (15). Even though the turtle had several setbacks, he still held his head high and looked forward down the path he was traveling, never forgetting where he was going just like the migrants. The dust and the turtle symbolize the journey of the migrants starting from the moment they were kicked out of their homes. The turtle is a better representation of how hard the migrants fought to reach their final destination, just to find they had to fight to live one day at a time. The dust is the best symbol Steinbeck uses to represent the bigger farms and natures roll in the future of the migrants. However both symbols represent the bigger picture, the perseverance the migrants had to use to survive each day on their journey, and each hour once they reached their overpopulated destination of California.

Social Cognitive Model of Resistance â⬠Free Samples to Students
Question: Discuss about the Social Cognitive Model of Resistance. Answer: Introduction Organizations are established with a hope that they will grow in terms of expanding their operations to other geographical areas, increase their revenue and open up new ventures with different mission and vision (cummings, worley, 2014). To achieve this fete, the organization needs to set goals that the organization should strive to achieve and which will serve as the vision of the business. The organization will also have to establish a comprehensive plan that will help the organization to achieve the set goals. Organizational planning can be described as the process that helps the business to identify the goals of the firm and put in place the relevant strategies that will help to achieve the goals of the organization (Goetsch, davis, 2014). Organizational goal setting refers to clear statements of tasks that should be accomplished to achieve the goals of the organization. This report is written to analyze HID case study. At present, HDs mission is to be the leading organization that has medium priced hotels in all the small towns and cities in Australia. Their mission is to build hotels in Australia as it serves as their geographical area of operation. The primary target market of hid is the market segment that can afford the medium priced hotels as they are based in small towns. Moving to large cities will mean that they need to raise their prices to meet the operational costs and they will also face stiff competition from the established hotels in big cities. The HID mission will soon change because the organization has set other goals and the business is planning to expand their business to large cities and even move out of Australia. The companys core purpose was to operate in Australia, but that mission will change because of the new set goals. The organization's mission was also to operate medium priced hotels, but that mission will change because hid is planning to change the pricing strategy of the organization because moving to big cities will automatically mean that the organization will have to change the pricing strategy. The hotels operated in big cities will have to charge high prices to meet their operational obligations. Failure to change the pricing strategy will force the business to make losses (Wagner iii, hollenbeck, 2014). The mission also changes to adopt a national outlook as the organization is planning to operate hotels in all cities in Australia and not focus on small cities. The organization is also planning to change the target market. The mission of the organization will change as there is need to align the mission of the organization with the plans of the organization. Due to business environment dynamics, organizations are forced to change their missions to continue operating smoothly (Zarkovic, cetkovic, knezevic, 2015). Change in organizations in inevitable and failure to change will result to business not operating effectively. Business planning also leads to the identification of new business opportunities which forces the organization to change its mission to exploit the new opportunities. At the end of the planning session, HIDs mission will be to operate the best large hotels in urban cities in Australia and the world at large with competitive prices. The strategic goals of HID are to move to urban areas in Australia and even in foreign cities and operate more than fifty hotels in ten years' time. Organizations should set strategic goals that should be clear so that employees can understand them because if the subordinate does not understand the goals the organization will not have a sense of direction (Hartley, 2014). The strategic goals should also be realistic and achievable and this is ensured by realistically assessing the business environment to ensure that it can accommodate such goals. Strategic goals of HID are likely to be effective as it has considered all the required factors when setting strategic goals and this will benefit the firm. HID's goal is to operate fifty hotels in ten years. This seems impossible, but with the right strategic plan, the goal is achievable. A strategic goal should be feasible, achievable and difficult to achieve (Smith, 2014). If the dream is achieved, it will lead to the growth of the business. Hid has also set the time frame to achieve the goals and this is very important in setting strategic goals and this will enable the organization to work hard to ensure the goals are achieved within the given time frame. Achieving the goals outside the stipulated time frame will lead to increased costs and the company will put the needed efforts to avoid these costs. The strategic plan helps the company to achieve its strategic goals. HID's strategic plan is to change the target market, change the pricing strategy, increase the workforce and come up with a plan to counter the increased competition. The target market will be people living in urban areas. This will imply that the plan will include introducing the products that satisfy people the tastes and preferences of people living in big cities. The company will employ the 4p's marketing mix which comprises of the price, product, promotion, and place (Pfitzer, bockstette, stamp, 2013). The products will be of high qualities to help minimize the high competition in urban areas. The products should also be innovatively produced, branded and packaged so as adopting high pricing strategy will be justified as the product reflect the customers value for their money (Bak?c?, almirall, wareham, 2013). The strategic plan should also show how the company will change the pricing strategy. The pricing strategy will be influenced by the target market. In some target market. Hid will use high prices because the new target market associates high prices with high quality. This means that charging high prices for hotels will help to attract more customers and minimize competition (Songini, gnan, malmi, 2013). In some urban areas, HID plan will be to offer products and services that fully satisfy the needs and of the customers and charge competitive prices. The strategic plan should also select the best strategic areas to set up the hotels. The hotels should be strategically placed in areas with a high number of the target market to ensure the hotels have enough customers. The strategic plan will also involve hid increasing the number of employees to work in the newly established ventures. Negotiating behavior was used to help the managers reach an agreement (Lent, brown, 2013). This is because each manager had his/her opinion on different goals of the organization. There was the need for the consultant to allow the managers to discuss to reach an agreement. During the discussion, the managers are given an opportunity to express their concerns and critique the other managers opinions. This ensures that the agreed decision is well analyzed and all the challenges that may hinder the achievement of the goals are known and planned for. The consult refocuses the discussion to ensure that the managers agree where their company should be to achieve their mission and tells them to support a national outlook for their company. No. Managers do not typically disagree on the direction of their organization. Disagreements between managers on the direction of the organizations are caused by various factors which include; Managers in an organization have different levels of experience. Some managers have adequate experience while others have little experience when it comes to organizational goal setting and planning (Klofstad, sokhey, mcclurg, 2013). The managers will little experience will tend to see some goals as being unrealistic because they have never set such goals before. This lack of experience will result to disagreements. Conflict of interest when making organizational goals will also cause the managers to disagree (Bateh, castaneda, farah, 2013). In the case of HID, managers new the mission of the organization was to operate within Australia targeting medium priced hotels. The CEO's goals for the organization conflicted with the current mission and the managers thought the goals were unrealistic because the CEOs goals were to change the pricing strategy, expand to urban cities in Australia and other foreign cities. Conclusion Due to business environment dynamics, change in organizations is inevitable. This forces the organization to change its goals and plans. This will also cause the organization to change its mission so that it can align with the goals of the organization. Organizations need to set clear, realistic, challenging and achievable goals. The strategic plan should be comprehensive to cover all the strategies to achieve the set goals. References Bak?c?, t., almirall, e., wareham, j. (2013).
