C1 Formation of bubbles, formation of a gas 12 D1 Formation of bubbles, formation of gas/smoke 3, 6, 7, 9 E1 Change in pH and temperature increase 1, 3, 12 F2 Physical change: formation of new substance 3, 12 Calculations: There were no mathematical calculations in this lab. Discussion/ Conclusion The qualitative analysis of the chemical reactions is displayed in tabular format above, listing the reason the experiment was selected, how I knew a reaction took place, type of chemical reaction, balanced molecular formula and balanced net ionic formula. In addition to my observations and the change in pH levels. To further explain why I selected the 6 chemical reactions I have listed the 12 principles of green chemistry below. 1. Prevention It is better to prevent waste than to treat or clean up afterwards 2. Atom Economy Design synthetic methods to maximize the incorporation of all materials used in the process into the final product. 3. Less Hazardous Chemical Syntheses Design synthetic methods to use and generate substances that minimize toxicity to human health and the environment 4. Designing Safer Chemicals Design chemical products to affect their desired function while minimizing their toxicity. 5. Safer Solvents and Auxiliaries Minimize the use of auxiliary substances wherever possible make them innocuous when used. 6. Design for Energy Efficiency Minimize the energy requirements of chemical processes and conduct synthetic methods at ambient temperature and pressure if possible. 7. Use of Renewable Feedstocks Use renewable raw material or feedstock rather, whenever practical 8. Reduce Derivatives Minimize or avoid unnecessary derivatization if possible, which requires additional reagents and generates waste 9. Catalysis Catalytic reagents are superior to stoichiometric reagents. 10. Design for Degradation Design chemical products so they break down into innocuous products that do not persist in the environment 11. Real-time analysis for Pollution Prevention Develop analytical methodologies needed to allow for real-time, in-process monitoring and control prior to the formation of hazardous substances 12. Inherently Safer Chemistry for Accident Prevention Choose substances and the form of substance used in chemical process to minimize the potential for chemical accidents, including releases, explosions and fires.

    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.
