H 2 N - (CH 2 ) 6 - NH 2 is the compound which is a raw material in the production of polymers. A number of N containing compounds which act as bases occur in nature These are known as alkaloids. In these compounds nitrogen may be present in the form of primary, secondary and tertiary amino grou..
Group 1 (IA) Element - Hydrogen
Hydrogen is the lightest substance known and the most abundant element in the universe. It has a mass of just 0.09 g per litre at normal temperature and pressure. Though it is present in abundance in celestial bodies, like the sun and stars, it is not present in a free state in our atmosphere..

Tutor has given me a lot of good advise for my study. They has the package to be the best and the best teachers! they are not just have the teaching skills and understanding the subject matters as well. Thank you.
Turtors are so good, and patient and most important knows their stuff. They really tutor in a very professional way. Their system is unique and they really knows how to explain and made sure you undertand. They even put stuff from a book into the white board, just to show me how the process of my question - Paul
