Ontario Curriculum 2008: Grade 11 Gas Laws and Atmospheric Chemistry OVERVIEW This course enables students to deepen their understanding of chemistry through the study of the properties of chemicals and chemical bonds; chemical reactions and quantitative relationships in those reactions; solutions and solubility; and atmospheric chemistry and the behaviour of gases. Students will further develop their analytical skills and investigate the qualitative and quantitative properties of matter, as well as the impact of some common chemical reactions on society and the environment. Fundamental Concepts Big Ideas Matter Energy Structure and Function Sustainability and Stewardship Properties of gases can be described qualitatively and quantitatively, and can be predicted. Air quality can be affected by human activities and technology. People have a responsibility to protect the integrity of Earth’s atmosphere. Overall Expectations By the end of Grade 11, students will: 1. analyze the cumulative effects of human activities and technologies on air quality, and describe some Canadian initiatives to reduce air pollution, including ways to reduce their own carbon footprint; 2. investigate gas laws that explain the behavior of gases, and solve related problems; 3. demonstrate an understanding of the laws that explain the behavior of gases. Specific Expectations By the end of this course, students will: F1.1 analyse the effects on air quality of some technologies and human activities (e.g., smelting; driving gas-powered vehicles), including their own activities, and propose actions to reduce their personal carbon footprint [AI, C] Sample issue: Gas-powered lawnmowers cut grass quickly and efficiently, but they emit greenhouse gases. However, there are several alternatives, including electric or push mowers or replacing lawn with a naturalized garden. Sample questions: In what ways does our consumption of products imported from distant countries affect our carbon footprint? How might “eat local–buy local” initiatives help to reduce our carbon footprint? How effectively does the use of digital communications for business reduce our carbon footprint? F1.2 assess air quality conditions for a given Canadian location, using Environment Canada’s Air Quality Health Index, and report on some Canadian initiatives to improve air quality and reduce greenhouse gases (e.g., Ontario's Drive clean program to control vehicle emissions) F2.1 use appropriate terminology related to gases and atmospheric chemistry, including, but not limited to: standard temperature, standard pressure, molar volume, and ideal gas [C] F2.2 determine, through inquiry, the quantitative and graphical relationships between the pressure, volume, and

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
