The first problem is that you're using non-English words. Check the words "chimical" and "milliards" - they don't exist in English!

Also, you need to use capitals and punctuation properly.  After you make those corrections, I'll be happy to have another look at it.

Until then... www.youtube.com/watch?v=q-RVJyNpfDk
