sir i didn't understand the first i made it more detailed for u though ty
Although DrWLS has taken care of your questions, and hasn't complained about the format, I want to suggest that you do the following:
1. improve your typing skills. It isn't easy reading a question with so many typos.
2. start each sentence with a capital letter and end each sentence with a period. It's tough to read a question and know when a new sentence begins and when it ends without proper punctuation.
3. write without all the texting characters. Most of us can figure it out, if we spend long enough to do it, but wen for when, wich for which, hav for have, u for you and ur for your, no for number as well as for know is very confusing, etc,, just adds to the time it takes us to formulate exactly what you are asking. Chemistry is tough enough without going through contortions to read it.
Thank you for your consideration.
