Welcome to the forum.
We welcome questions but this forum is more about self help, we expect members to read and research to find the answers themselves, if you find something you can’t understand then feel free to ask, no one here is paid so help is a luxury not a requirement from others.
Read and study until you understand the basic chemistry behind this hobby as that makes answering any questions you may have understandable to you.
Good luck and get reading 8)
