I'd like to welcome you,
helpme2: to the chemical forums, but I'd like to remind you to read the
Forum Rules{click}. You agreed to read and follow them when you signed up, and they apply to everyone, regardless of their circumstance or personal opinion.
For everyone's convenience, I've attached four of the images to your post, and the fifth one is here, because our rules don't allow five images per post. Which is part of the point, dumping five disparate questions, and saying "Urgent" is no way to learn anything. If you truly tried to find these answers, in your text book or class notes, and failed completely, then you likely have many other gaps that you'll have to fill before exam time.
Spend some time trying to learn what you missed and why, and then try to come back with a difficult question, or two, and show how you began to try to solve it.
