Consider the cubic perovskite LaFeO3, in which the iron center is high-spin a. Do you expect a Jahn-Teller distortion? Why or why not?
b. Do you expect the interactions between iron centers to be ferromagnetic or
antiferromagnetic? Explain why, and show the orbital pathways involved in the
magnetic interactions.
c. Sketch qualitatively what the magnetic susceptibility (χ) of this compound would
look like as a function of temperature.

increased stability in the completion of fluorine's outer shell.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
