Hf2- is linear and
symmetrical, f-h-f- and has one of the strongest systems
of hydrogenbonding
a) draw atomic overlap representations for each of the sigma and
piorbitals of hf2-

b) draw oa mo energy level scheme for the molecule. place h atom 1s
orbital on left, fluorine 2s and 2p orbital (or the
appropriatesalcs) on right, and orbitals of hf2- in center.

c) given evergy level scheme derived in part b, would you
expecthf2- to be diamagnetic or paramagnetic

d) what is the h-f bond order in hf2-?

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant. 

What’s the solution?
