Hydrogen cyanide is a tri-atomic linear molecule. In
units of atomic mass units u, the masses of the atoms are: H = lu,
C = 12u, N = 14u. In units of angstroms A, the bond lengths are:
H-C = 1.06A, C-N = 1.16A. How far from the hydrogen atom is the
molecule’s center-of-mass?
180°
Americium-240 has a half-life of 2.12 days. (Can you see why americium-241 is used in smoke detectors rather than americium-240? See exercise 4.) How many hours does it take for 34.5% of a sample of americium-240 to decay? answer should be 31.1 hr

Americium-244 is a rare isotope of Americium. What is the mass defect of Americium-244? Use the following values for atomic and neutron masses when calculating your answer: Am: 244.064279 u H: 1.007825 u n: 1.008665 u
A hydrogen chloride molecule consists of a hydrogen atom whose mass mH is 1.01 u (atomic mass units) and a chlorine atom whose mass is mCl is 35.0 u. The centers of the two atoms are a distance d = 1.27 × 10−10 m = 127 pm apart. We want the rotational inertia Icom of the molecule about an axis perpendicular to the line joining the two atoms and passing through the center of mass of the molecule. We will...
