How can a mathematics teacher can teach chemistry for 12th student and the parents also expecting only...

Upto class 10th it's possible but after that the kids need specialist of each subject to teach them properly. It has nothing to do with your intelligence because here in India most people have only majored in one subject and they haven't learn other subjects in depth to make the subject easier for students.

If you want to speak in a particular language then first you need to listen to it. Start from the beginning. Like when we were born. We heard others speak and we tried to repeat the same without actually knowing what we are saying. It is similar but easier because you probably know how to read and write which we didn't for a long time when we first learnt our language (Hindi for me ). Now what you need to do. 1.Read not just newspapers and magazines but novels because newspaper doesn't contain any dialogues that we use in our daily lives. I would suggest books by American or British author and contemporary genre. 2. Watch English movies and TV series at least an hour a day. So that you will know how natives pronounce those words you might have difficulty with. Look at the way to form their mouth to make your pronunciation better. 3. Install an English language learning app not the vocab building apps but language guide one these apps teach these languages from the beginning which is very helpful. 4. Try writing journal in English. Just note down your thoughts and stuff. Whatever is happening in your life. What you did that day and where you went. 5.Try to think in English instead of your native language. Like if you daydream do that in English. It might sound stupid but trust me it helps. That's all. Hope it helps.
