sorry i dont know answer of second box

but i tried my best

n it was simple to write chemical eqautions

n second u have to write tempearature of reaction

hope u understand

Answer 2

An isotropic material of relative permittivity is placed normal to a uniform external electric field with an electric displacement vector of magnitude 6 * 10-4 C/m2 . If the volume of the slab is 0.7 m3 and magnitude of polarization is 5 *10-4 C/m2 . Find the value of PERMITTIVITY and total dipole moment of the slab.
