You watch water falling from the top of a waterfall to the bottom. How would you characterize this physical phenomenon in terms of spontaneity? What if you wanted to move the water from the bottom of the falls to the top—how would you characterize that reaction?Consider the following reaction occurring in a closed chemical system. Assume that this reaction is at equilibrium and that in general the reaction to the right is favored.CH3CH2OH + 3O2 ⇄ 2CO2 + 3H2O ∆H = –1,235 kJ/mol What type of chemical reaction is this? If more CH3CH2OH is added to the system, how will the reactions shift to reach equilibrium again? If water is extracted from the system, how will the reactions shift to reach equilibrium again? If heat is removed from the system, how will the reactions shift to reach equilibrium again? What is the name of the principle that helps you predict each of these shifts in equilibriumThis graph shows the energy involved in a reaction involving two molecules. Describe what is happening or what the state of the reaction is at A, B, C, and D. Then tell if this is an exothermic or an endothermic reaction.**Graph is located in the PDFChalcocite is an ore from which copper can be extracted for commercial use. The formula for this important ore is Cu2S. In the laboratory it is formed by the following reaction:2Cu + S → Cu2SThe reaction takes place in laboratory conditions that allow the reactant atoms to move freely about in the reaction vessel. Explain this reaction in terms of collision theory.

The Discussions are not simply statements of opinion. They are intended to allow you to expand upon and apply the principles discussed in your textbook, the lectures, and/or other research you conduct. Each week a question will be posed for your consideration. Before answering, you should review the chapters covered during this week and the lectures.Many of the farm-grown/farm-raised foods available today have been treated with pesticides. Meats, which we eat like beef and chicken, have been irritated. Why are radioactive substances like Cesium 137, Cobalt 60 and Plutonium 238 used to irradiate our food? Some benefits are radiation kills bacteria, the nutrtitional value of the food is preserved and food spoilage is reduced and food shelf life is extended. However there are negative side effects of this technology that everyone must be aware of and understand. For the Week 2’s Discussion we will be talking about Irradiated and Genetically Modified (GM) foods. When discussing this topic in your initial post the following points must be addressed:Irradiated foods1. Discuss a farming practice or treatment practice used to treat crops, crop products, raise animals or treat meats.2. What are some of the reported effects of the treatments on people? [Sources of information must be reliable and credible scientific resources.]3. How are these practices being monitored by the U.S. Federal Government?4. How can the general public research how their food is grown?Your initial post to the discussion is required to be completed and posted by 11:59 p.m. ET Thursday of Week 2. Your initial post is required to be on a specific radiation or genetically modified process that has NOT been posted on by another student AND at least 250 words. This MUST be in your own words. You are required to include at least one credible and reliable scientific resource of information ONLY and research carefully. Do NOT use ANY open blog or ANY open source where anyone can post responses and the information is not verified. Please do not plagiarize. Properly cite information used from outside resources per APA with in-text citations immediately following the information and a full reference citation at the end of discussion post. Review the “Credible References/APA format” folder in the ‘Start Here’ area of the classroom for additional information on Researching Information and properly citing resources used.You are then required to make at least two additional posts to two other students [or one student and the professor] on two separate days and not posted on the same day as your initial post. The response posts should be at least 100 words and be substantive in nature. If a reference is used in writing a response post, it must be an appropriate and reliable academic resource as it is with references used for the initial discussion board response. While pleasantries such as "I agree" or "great job" are nice, they will not count as one of your required posts. A complimentary, philosophical, or off-topic comment does not count as one of the three required entries. For example, it does not help us to tell us that you did not know something before you read an entry. All entries should help everyone understand one or more of the concepts presented.
