In the ammonia (NH_3) molecule, the three hydrogen (H) atoms form an equilateral triangle; the center of the triangle is 9.40*10^-11 m from each hydrogen atom. The nitrogen (N) atom is the apex of a pyramid, with the three hydrogen atoms forming a base. The nitrogen-to-hydrogen atomic mass ratio is 13.9, and the nitrogen-to-hydrogen distance is 10.14*10^-11 m. Locate the center of mass of the molecule relative to the nitrogen atom, and explain how you got your answer.

Do you really think scientistS found a way to make things invisible??? I mean, why spend billions of dollars to make things invisible when you can use that money to do something actually useful!!! I mean, give starving children food, or BETTER YET, HOW ABOUT REBUILDING NEW ORLEANS AND FLORIDA?!?!?!?!? THE SCHOOL SYSTEM IN NEW LONDON, CT??!?!?!??

OR MAYBE, BUILD HOMES FOR ALL THOSE PEOPLE WHO LIVE IN TENTS AND JOB OPPURTUNITIES FOR PEOPLE WHO ARE STUCK GOING TO 'LABOR READY' FOR THE REST OF THEIR LIVES?!?!?!??

The only two elements in the periodic table which can form long polymer chains are carbon and silicon, both of which have valency 4. Why can't you have, say a long chain of oxygen atoms, or a chain of nitrogen atoms with a hydrogen hanging to each nitrogen ? And tin is in the same column as C and Si, so why doesn't it form long chains with other atoms and functional groups attached to each tin atom in the chain?
