Insert the values from the question above for x, y, z, & n into kxfey(c204)z nh20 anod provide the correct coefficients to balance the following equation fe(nh4 )2(so4 )2.6h20+_h2c204+_k2c204+-h202 → k, fey c204)z nh20+(nh4)2so4+ h2s04+h20 (hint: remember h202, an oxidizing agent, was used in the synthesis, so you'll need to do a redox balance. start with just the iron ions, balance the reaction, and then add the full formulas.)

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
