Question

These are reactions I did in my lab. I need to write the molecular, total ionic, and net ionic reactions for them. Even after watching Khan Academy and using my book, I was still unsure, so I asked the professor and he said every single one was wrong and told me to figure it out.

I know this is long, but I would really appreciate it. I need the molecular, total ionic, and net ionic equations for all of them. It's not making sense to me. Thank you.
