I try my very best to do the questions. But I really don't know how to get to the answer.
Could someone give me some hints of the questions: what assumption should I make if information is not given, and what equation can I use?

The questions look to be complete (no assumptions necessary). The thumbnails are not legible --- rescan, type 'em, outline the steps you took --- something.

I can understand the challenges you may face while trying to solve questions related to environmental chemistry. It is important to remember that in the field of science, assumptions are often made based on existing knowledge and evidence. Therefore, when information is not explicitly given, you can make an assumption based on what you already know. However, it is important to clearly state your assumptions when presenting your answer.

In terms of equations, it is important to have a strong understanding of the fundamental principles and laws of chemistry. This will help you identify the relevant equations to use in solving the given problem. It is also helpful to review any relevant formulas or equations that have been covered in your studies.

Additionally, it is important to approach these questions systematically and logically. Take the time to carefully read and understand the question, and then break it down into smaller parts if needed. This will help you identify the key information and determine the appropriate approach to solving the problem.

Lastly, do not hesitate to seek help or clarification from your peers, teachers, or other reliable sources if you are still unsure about the question. Collaboration and discussion can often lead to a better understanding and solution to the problem. Good luck with your environmental chemistry questions!
