Directions: Read each scenario describing chemical reactions related to acid rain pollution in the environment. As you read, answer the accompanying questions. You will need to reference your notes from Task 1 as you work. What is acid rain? Acid precipitation is rain, snow, fog, or dew that has a pH of less than 5.6. Click on this article to read about it. 1. According to the article, what causes acid precipitation? When Sulfur dioxide and nitrogen oxides are emitted into the atmosphere and transported by wind and air currents. Coal and oil contain sulfur and when burned in factories and power plants, the sulfur combines with oxygen in the air and is emitted into the atmosphere. The gas then undergoes chemical…

A community member living in a highly populated city has asthma, which increases sensitivity to certain air pollutants. The AQI value for a particular day is 45. Which statement describes the most appropriate reaction of this community member? Because the air quality value is considered unhealthy for all groups, the community member decides to stay indoors that day. Because the air quality value is considered unhealthy for all groups, the community member decides to go about a normal daily routine. Because the air quality value is considered unhealthy for sensitive groups, the commu- nity member decides to wear a mask outside for additional protection. Because the air quality value is considered satisfactory, the community member decides to go about a normal daily routine.

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…
