I need help finding reactions beneficial to society. Here's the assignment quoted.

"Your assignment is to research two different chemical reactions that are used to address social/environmental needs or problems. These reactions must clearly be attempting to improve our world. Ex. A scubber reaction is used to reduce or eliminate air pollution by removing or neutralizing exhaust gases. (This example cannot be used). The key is that you must be able to identify the chemical reaction and demonstrate that it has clear benefits to society/environment and addresses an existing problem or issue."

The scrubber reaction would have been a great one to use; however, that is out. So what about a different kind of scrubber (which isn't called a scrubber)? I think you could pick the reactions in the exhaust pipe of an automobile and how the catalyst removes NOx and SOx gases. That is an environmental problem. Look on the web and see if you can find enough information about the catalysts used and how they work.

Would the reactions going on in an air-bag inflation system on an auto be a society problem (it keeps people from dying in an accident which seems to me to be a part of society). You be the judge. Keep these two in mind while you whirl your brain cells around a little. You may be able to think of some, now that I have teased you into the right path, that are better.

To find chemical reactions that address social or environmental needs and have clear benefits to society, you can follow these steps:

1. Identify social and environmental issues: Think about problems or challenges in society and the environment that you believe require attention. Consider issues such as air or water pollution, renewable energy, waste management, climate change, or resource conservation.

2. Research existing solutions: Look for existing efforts or initiatives that deal with the identified social or environmental issues. Explore scientific research articles, reports, or reliable sources to understand the different approaches and technologies that are currently being used.

3. Analyze chemical reactions: Once you have identified a social or environmental issue and its existing solutions, examine the chemical reactions involved in addressing those problems. Determine how specific reactions can contribute to solving or mitigating the identified issues.

4. Evaluate benefits to society/environment: Assess the potential benefits provided by each chemical reaction. Consider how the reaction reduces pollution, conserves resources, improves energy efficiency, promotes sustainable practices, or addresses other social and environmental needs.

5. Choose two reactions: Select two chemical reactions that have clear benefits to society/environment and effectively address existing problems or issues. Make sure the reactions are distinct from each other to showcase a range of solutions.

Remember to support your findings with credible sources and scientific evidence when presenting your research.
