Exit Fullscreen For this assignment, you are required to conduct research on one of the following energy sources within Canada: • Fossil fuels • Nuclear energy • Biofuels • Wind energy • Solar energy You will research how the energy is extracted or produced, and provide details about the chemical process (stating equations and reactions). Your work must also include a comment on the impact your chosen energy source has on the environment and society. This assignment is worth 15% of your course grade. Instructions Assignment components Ensure your assignment includes the following pieces of information relevant to your chosen energy source: • The name of your chosen energy source and a brief description of what types of compounds are used in the production process • Details about the chemical process, stating balanced equations and reactions • A calculation of bond dissociation energy for the reaction, accompanied by an explanation of what the value indicates • An analysis of the impact…

Dangerous Paint Stripper Jessica has a summer job working for the city parks program. She has been using a cleaner called “Graffiti Gone” to remove graffiti from the bathrooms. She has to take a lot of breaks, because the chemical makes her throat burn. It also makes her feel dizzy sometimes, especially when the bathrooms don’t have very many windows. On the label, she sees that the cleaner has methylene chloride in it. She feels like she’s managing to get the work done, but she is worried about feeling dizzy. She wants to find out more about this chemical, what harm it can cause, and whether there are safer ways to do this work. Questions for following story. 1. What went right in this situation? 2. What went wrong in this situation? 3. What steps should be taken in this workplace to make sure employees are better protected and prepared the next time?

Module 14 Discussion: Logarithmic Application A Radiative Forcing Radiative forcing, R, measures the influence of carbon dioxide in altering the additional solar ration trapped in Earth's atmosphere. The International Panel on Climate Change (IPCC) in 1990 estimated k to be 6.3 in the radiative forcing equation R = k In(), where Co is the preindustrial amount of carbon dioxide and C is the current level. (Data from Clime, W., The Economics of Global Warming, Institute for International Economics, Washington, D.C.) (a) Use the equation R = 6.3 In() to determine the radiative forcing R, in watts per square meter (W) to the nearest tenth, expected by the IPCC if the carbon dioxide level in the atmosphere doubles from its preindustrial level. (b) Determine the global temperature increase T, in degrees Fahrenheit to the nearest tenth, that the IPCC predicted would occur if atmospheric carbon dioxide levels were to double, given T(R) = 1.03R.

Paragraph 5: Discuss Fractional Distillation of petroleum oil to give the chemical feedstock to make synthetic polymers for commercial use of products in our daily lives and discuss your personal thoughts on incresing US drilling in the Gulf of Mexico or in the Artic. Think about it, every time you go to the grocery store and get a plastic bag which immediately gets discarded. Include your thoughts on mandatory recycling in the US especially for schools, government buildings, etc.

TRUE LIES: There are many misconceptions regarding fire. A person must equip himself with factualinformation to guarantee safety. Not all shared information is true. So, can you spot them?Direction: Below are statements about basic information on fire. On your answer sheet, write TRUE if thestatement expresses a correct idea, otherwise write LIE.4. Fire is a thing, not an event.5. Assuming stable fuel, heat, and oxygen levels, a typical house fire is constant in size every minute until the firedies down.6. Earth is the only known planet where fire can burn.7. Water can be produced by fire.8. Using concentrated sunlight, ancient Greeks were able to start fire. A parabolic mirror that focuses solar rays isstill used to ignite the Olympic torch.9. Among the stages of fire, the last stage which is the “decay stage” takes the longest time to finish.10.All fire extinguishers are multipurpose, meaning each one can put out all types of fire caused by any material.NOTE: JUST THE ANSWER ONLY NO…

Please answer the following question:

Go to the interactive. Use the Single Collision tab to represent how the collision between monatomic oxygen (O) and carbon monoxide (CO)results in the breaking of one bond and the formation of another. Pull back on the red plunger to release the atom and observe the results. Then, click on “Reload Launcher” and change to “Angled shot” to see the difference.(a) What happens when the angle of the collision is changed?(b) Explain how this is relevant to rate of reaction.

Read the questions carefully and answer them comprehensively.
