Calculate the reduced mass of a nitrogen molecule in which both nitrogen atoms have an atomic mass of 14.00. Do the same for a hydrogen chloride molecule in which the chlorine atom has an atomic mass of34.97. Hydrogen has an atomic mass of 1.008.

Explanation:

To calculate the reduced mass of nitrogen molecule = Mn x Mn/ Mn + Mn

Mn = atomic mass of Nitrogen =  14.00

reduced mass = 14 x 14 /14 + 14 = 7

Similarly for HCl; reduced mass for a hydrogen chloride molecule = Mh x Mcl/Mh + Mcl

where Mh = atomic mass of hydrogen = 1.008

Mcl = atomic mass of chrorine = 34.97

reduced mass for HCl = 1.008 x 34.97 /1.008 + 34.97

= 0.97

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
