Information regarding Curie temperature is given. Paper clips made of nickel are held near permanent magnet and these are given to get attracted. One of the clips is observed to fall down when the one of the paper clips is heated. The reason corresponding to this phenomenon is to be stated. Concept introduction: When spin of the unpaired electrons of ions or atoms of the solid align themselves in the direction that is same as the direction of the neighboring atoms or ions, then the substance behaves as a permanent magnet and the magnetism shown by such a substance is called ferromagnetism. The paramagnetic substances are the substances in which the spins of the electrons of the ions or atoms are randomly oriented. To determine: The reason for the falling down of the nickel clip when one of the clips is heated.

Using reaction free energy to predict equilibrium composition Consider the following equilibrium: 2NO2 (g) = N2O4(g) AGº = -5.4 kJ Now suppose a reaction vessel is filled with 4.53 atm of dinitrogen tetroxide (N2O4) at 279. °C. Answer the following questions about this system: Under these conditions, will the pressure of N2O4 tend to rise or fall? Is it possible to reverse this tendency by adding NO2? In other words, if you said the pressure of N2O4 will tend to rise, can that be changed to a tendency to fall by adding NO2? Similarly, if you said the pressure of N2O4 will tend to fall, can that be changed to a tendency to '2' rise by adding NO2? If you said the tendency can be reversed in the second question, calculate the minimum pressure of NO 2 needed to reverse it. Round your answer to 2 significant digits. 00 rise ☐ x10 fall yes no ☐ atm G Ar 1
