Hi guys, I am in a really tough spot right now, I recently moved to a senior high school and I have obviously been adjusting really terribly cause my grades have absolutely plummeted.

Hi, I recently received a depth study for Chemistry, in which we are tasked with creating a in depth question about the application of catalysts in the industry. After this, we will have some sort of in class assessment, for this. I am not sure what question I should do, and what they might ask...
